I participate in the PUPCWTS++ initiative as a mentor for volunteers undertaking their National Service Training Program, collaborating with a the San Juan campus of the Polytechnic University of the Philippines.
One of our program objectives is to provide the participants with a better appreciation for spatial data, and the same time, provide them with digital mapping skills, by contributing to other open data projects. We also would like to impart the value of volunteerism in them, and what it takes to become (digital) humanitarians.
Back in June, before we started, this is how the Philippines looked like with ImproveOSM:
And today, this is how the country looks, compared to the rest of southeast Asia:
Apart from missing roads, they also work on mapping communities in many parts of the Philippines, especially around Lake Sebu in Mindanao, as well as mapping their own neighborhoods in Metro Manila, where they live, using a variety of open tools: FieldPapers, JOSM, and capturing street-level imagery usng Mapillary or OpenStreetCam.
They also hone their skills by working on other tasks, like a number of road network improvement we have in Kaart, and contributed to recent disaster response tasks in Laos, India, Japan, and various projects in Africa.
It is a delight to tell you that our young volunteers work on most of these tasks using their own time, outside the classroom setting. Our classroom sessions are dedicated to learning new skills or techniques, and to discuss issues encountered, or to exchange feedback.
I thought of adding a group photo, but realized that we never had taken the time to pose for a good group picture. :D)
If you see a
#pupsjcwts hashtag in a changeset comment, it would be if you could leave them some constructive feedback.
It's been almost a week since I got back from Davao, but I've yet to write anything down about the OpenStreetMap activities we had there. So, here's a quick round-up:
"Open Source Mapping" with Tambayan Center
"Is the Bermuda Triangle for real?"
This is the most interesting question I got from this workshop!
This mapping project was in the pipeline since the middle of 2017 when Tambayan Center sent me a query over email, and it just happened that I was also in Davao at that time. I dropped-by (and, of course, mapped ) their office to get their feet wet about OSM, and maps in general, and listen to details of what they're trying to do. Tambayan Center is a long-standing NGO operating in Davao and working mostly with concerns and rights of young people, and their communities.

It was fun working along-side Jen, and engage a younger set of volunteers (ages: 11-18) with a fresh style. She's a passionate mother, and advocates for womens' rights in various ways, apart from working with geo-stuff.
Tambayan Center workshop activities: Editing, Field work, Community validation, Fun
Expect a more detailed write-up soon. Right, Jen? I'm looking forward to seeing that. I hope you do, too.
Mapping with OpenStreetMap x Ateneo de Davao University
Mr. Glenn Depra of Ateneo de Davao University organized a workshop for faculty members of the university, with their Social Research Training and Development Office hosting the affair. This was originally intended as a workshop that would be made open to the public, but due to last minute hitches, we decided to defer offering it for another time.
The workshop included a general coverage of available (Free software), editing tools, data collection , and how to make use of OSM data, including Q&A segments for specific concerns.
Some of the participants were also from a group people Maning Sambale met during a mapping party back in 2009. They are surprised to find out that many of major map features added on OSM stems back from that mapping party made almost 9 years ago.
The Ateneo community is enthusiastic about helping promote OpenStreetMap (and Open data) not just for their academic pursuits, but also to engage other communities and organizations in Davao.
Instant meet-up with a local mapper
With my luggage in tow, coming in late from another meeting, and off to another afterwards.
Whenever I'm tramping about, I try to connect with local mappers, and chat about maps, open data, and free software. Of course, this often leads to (hours of) talking about so many other things. It's good meeting you, Alex, and I hope we'd see you in another workshop soon.
Yesterday, a unit of the Social Welfare Department organized and hosted MapaBabae - an OpenStreetMap workshop for Women, with Women - in their central office in Quezon City, to mark Women's Month, and to introduce OSM as a tool for mapping, and to promote the value of diversity and inclusiveness in any community.
Kudos to the organizers for a refreshing take of mapa-thons, and the interesting discussion about language, empowerment, the potentials of open data in their work.
Jen, draws inspiration from the local Geo Ladies first (and only?) meet-up from 2014
As with other mapping activities, they also learned and edited maps of their communities. However, I found the discussions, and questions, more interesting.
A notable query was: "what's the tag for baby feeding rooms?" I did a quick search, and to my surprise (and dismay), there's no accepted convention. And yet, a proposal for baby_care was made in 2015.
I wish to see (and hope to support) more outreach activities to encourage diverse participation, and with more people organizing thematic mapping activities, to help map the communities they live in, work with, or simply because they love to map. The challenge of gender and language (and even the use of "mapa-thon") as a possible discouragement to mapping was eye-opening.
Helping change the ratio. 17:24
There are a few more photos here.
Happy to see folks from various communities coming together to celebrate ODD with us.
Last Saturday afternoon, we celebrated Open Data Day 2018 in PUP San Juan, with several volunteers from OpenStreetMap Philippines and the local FOSS4G chapter facilitating the parallel workshop sessions we ran.
We mark Women in History month with a beginners' workshop led by the P̶o̶w̶e̶r̶p̶u̶f̶f̶ ̶G̶i̶r̶l̶s̶ awesome ladies of the OpenStreetMap volunteer community 😹:

For intermediate users, we offered a session on Geopandas, and another for Adjusting Imagery Offsets and alignments:
RK (left) during the Geopandas session, and Rally on Imagery Offsets
Meanwhile, the unconference session included a couple of lightning talks, and several impromptu ones that made the discussions more lively and interesting:
Marx facilitating the open discussion on Open Data and DRR unconference. (P.S. Don't mind that object on the floor)
We had students, NGO workers and volunteers, academics, developers, and GIS specialists. We had a good mix of community enthusiasts, private sector representatives, and some civil servants.
We have a number of participants who traveled quite a ways to participate.
Aaron from the Peace Corps is working with the local government of Carigara in Leyte, and he's been supporting the municipal DRRM office in their effort to comprehensively map their town. He travelled a few days ahead of a scheduled trip to Manila, to join the activity.
Pierre showcases their activities in the YouthMappers chapter of the FEU Insititute of Technology.
Martin is flying out of the country that same evening but decided to "drop-by" and participate in the event. His work on LIDAR and his experience with open data, contributed a lot during the unconference discussions.
Ayoo did an impromptu demonstration of WebSafe, as a response to a question from an unconference participant. He used to work with Project NOAH, as a developer of Websafe.
There are many others who selflessly shared their time with us. We're grateful you came over. It wouldn't have been the same without you.
A special shout-out goes to the crew of volunteers from the university who provided general assistance throughout the event:
More photos from the event are now online.
The Free Software and Open Data advocates of Manila is going to celebrate international Open Data Day 2018 on March 3, Saturday with an afternoon of Open Mapping workshops in San Juan Campus of the Polytechnic University of the Philppines, in Metro Manila.
The event is open to everyone, with parallel activities available, depending on your experience and interest:
- [Workshop] Introduction to Open Mapping with OpenStreetMap
- [Workshop] Intermediate+ Mapping on JOSM
- [Unconference] Open (geo)Data for Disaster Preparedness and Resiliency.
In the beginner's workshop, a computer laboratory will be available for your use. Limited seats are available.
In the intermediate workshop, participants are required to bring their own laptops, with JOSM already installed. This workshop is intended for participants with some JOSM experience.
No computers are necessary for the unconference. Just bring some enthusiasm, and an open mind.
Refreshments and swags are to be given away, for registered participants.
The areas surrounding Mayon volcano is still in Alert Level 4, which means an imminent hazardous eruption is expected.
We'd like to share the progress of the hard-working humanitarian volunteers who has already mapped 91% of Mayon's Extended Danger Zone 0. Last week, volunteers also completely mapped Mayon's Permanent Danger Zone 1. We'd like to especially acknowledge the big mapping boost we got from the DevSeed data team from Peru.
The southern section of the EDZ, considered as high priority because of the settlements within, are now 100% complete, and validated.
For interested parties, the data from OpenStreetMap may be extracted immediately using the HOT Export Tool, and this export 2 in particular, which conveniently provides data in ESRI shape file, as routable maps for Garmin devices, and for offline use with smartphone apps (OsmAnd, and Maps.Me) This export may be re-run, to refresh the extract. It may also be cloned, and customized for your own needs.
Thank you for doing your best.
Very active mapping activity around Mayon, in the last several days.
We are grateful for the help extended by very dedicated mappers all around the globe, for helping map the Permanent Danger Zone around Mayon. This has been 100% validated today.
Mt. Mayon is still a looming threat for many towns and small settlements in its vicinity, and we have an on-going mapping project to map the Extended Danger Zone. And because of the positive response from the community, we're now halfway done, and would welcome extra helping us to make this complete as soon as possible.
Kudos to Maning Sambale for initiating this activity, to make available Free and Open geodata to local governments and humanitarian organizations for their disaster management planning, and response.

Mayon, the Philippines most active volcano, with 48 historical eruptions is restive. Over the weekend, tremors, lava fountaining, and lava collapse events has been noted. Government volcanologists report that “relatively high level of unrest as magma is at the crater and hazardous eruption is possible within weeks or even days.”
The authorities has prohibited the public from entering the 6 kilometer-radius Permanent Danger Zone (PDZ), and the 7-km Extended Danger Zone (EDZ) on the southern flanks “due to the danger of rockfalls, landslides and sudden explosions or dome collapse that may generate hazardous volcanic flows.”
Yesterday morning, we appealed for help to map the 6-kilometer Permanent Danger Zone of Mayon, and the community responded quickly. Today, it's been 100% mapped, 57% validated (and still on-going). Thank you! The names of the generous mappers may be found in the project dashboard.
Mayon Permanent Danger Zone (PDZ): 100% mapped. 57% validated.
Today, a new project to map the 7-kilometer Extended Danger Zone (EDZ) around Mayon has been published: https://tasks.hotosm.org/project/4037 and we are again appealing for some of your precious time, and valued mapping skills, to map the EDZ. Most especially the priority tasks in the southern quadrant, where there are a number of villages and settlements.
Again, this is preemptive mapping activity to assist local government agencies and aid organizations to support future damage assessment. We call on the digital humanitarian community for their assistance for this project.
On-going humanitarian mapping around Mt. Mayon, Albay, Philippines
This morning, barely 12 hours ago, the OpenStreetMap volunteers from the Philippines set up a task to map an area threatened by the restive Mt. Mayon.
And the global community of digital humanitarians quickly responded:
48% mapped. 7% validated.
We're not done yet, but we wish to acknowledge everyone who quickly responded to our call. Thank you, folks. You're awesome - and you know it. ;)
If you have some minutes to spare, we still have a little over half to complete: https://tasks.hotosm.org/project/4027
Last week, we shared a a tasking project to update missing highways in Metro Manila 0 in the local mailing list. We've also published a few more tasks to cover adjacent provinces:
The data is not perfect, and you may even encounter false positives, but it's pretty good with pointing out a good number of missing roads in essential areas that local mappers have yet to digitize.
These are all part of the on-going initiatives by Kaart, to make awesome data for PH, and help grow local mapping communities.
If you're keen on improving the map of your home town or province, and they're not on this list yet, please let me know so I can put them up sooner rather than later, and we can work together in filling-in gaps in your favorite neighborhoods.
How about a mapa-thon soon? I'm planning to organize one, primarily to work on these tasks, and for the community to meet each other, and maybe welcome new ones. Would you folks have any suggestions, or is your org interested in collaborating? Let me know.
See all the Missing Highways tasks in PH. Do email me for any concern, or other questions, about these tasks.
Earlier today, we (belatedly) celebrated Geoweek 2017 with students from the University of San Carlos of Talamban, Cebu. Many thanks to Ms. Rose Lapad (Cebuano Studies Center) and Ms. Lalia Labajo (Chairperson, Department of Anthropology, Sociology and History) for accommodating the mini workshop to introduce OpenStreetMap to their students.
We were able to do basic editing with iD, work with the Tasking Manager, and capture a few Mapillary imagery of the campus, plus the usual Q&As for beginners.

Thank you Carolinians! I hope to see more mapping activities in your neighborhoods soon.
I always enjoy reading many diary entries, and since this is a very global community, it's not a surprise to see many people writing in their native languages.
I'd love to see an translate link or button under each entry (and comments). It's not perfect, but for the most part, you get a gist of what the author is saying:
Our Zen Center hold a regular outreach progam for kids called Bodhi Star. Along with teaching basic mindfulness techniques, life-skill ideas and concepts are also taught or introduced.
Yesterday, it was my turn to teach skills class and I've always been keen on teaching something related to maps and geography.
The kids had great fun trying to identify objects from aerial imagery, "visiting" remote places, and wonder about the beauty of our vast, interconnected world.
Some of the places we visited had limited street-level imagery, which they were quite fond of, so I even got to discuss Mapillary with some of them - who wanted to capture images of their neighborhood. There are plenty of caveats, of course, and there are parents around to keep them grounded.
I should seriously plan for a Mapillary field-trip idea for kids.
As always, the local OSM community in the Philippines is keen in finding ways to engage, and expand the community of OpenStreetMap contributors in the country. Many mapa-thons and hacking events are fueled by passion, and pizza. You can help drive the passion, and we'll take care of the pizza.
We just launched a new program: the OSM PH-izza Challenge that offers to send free ph-izza for mapathon events in every possible part of the country - especially those outside Metro Manila. If the mapathon proposal is selected, the PH-izza is on us!
We're hoping to select at least one event every month - and we'd like to hear your proposal!
If your group or club would like to send your proposals, please fill-in this application form so we can evaluate your them: https://goo.gl/forms/si06mto1fOkeY3652
P.S. We would also be very happy to hear from pizza-hearted sponsors who would like to help us expand this program!
This post is a month overdue. I was in the Davao region last August (for business), but I thought I should touch bases with a few local organizations, including the local fire department, to chat about OpenStreetMap, since I'm there anyway. :smile:
My inquiries were enthusiastically received by the local fire officials as I introduced the goals of the HailHydra(nt)! initiative, and they decided they're willing to host a mapa-thon. We set it during the city's annual Kadayawan Festival.
Looking back, I should've pushed for another date. With many other departments busily attending to their own programs and tasks for the said activity, we ended up doing the mapping ourselves, instead of the expected participation of other orgs, we still managed to complete the goals we set for the day, with a little overtime :grin:
A Fire Hydrant Network base map
The main objective is to map the fire hydrants of the city, and complete the map of the fire stations and volunteer brigades operating in Davao.
From 18 to 673 hydrants
Their official data actually reported 870 hydrants, but because of this activity, I actually discovered that they are reporting 197 duplicate data! :eyes: We started with just 18 hydrants in the OSM database, and at the end of the day, with a lot of help using the OSMHydrant app as editor, we completed the 673 hydrants of the city.
The Fire Station and Hydrant map of Davao (and parts of Samal Island)
Working Offline, and Mobile using OsmAnd
Immediately after completing the map, they wanted a map (and an app) they can use in their Smartphones. OsmAnd is my go-to app - it's Open Source and Free, flexible, and can work with off-line. Perfect! I recommend the community-maintained version from F-Droid.
We demonstrated how they may use the HOT Export Tool to create an offline database for OsmAnd, instead of waiting for the monthly updates. In the course of the orientation, we discovered a bug, which has thankfully been fixed in the upcoming version 3 of the Tasking Manager.
They are keen to include the use of OsmAnd and OpenStreetMap in their operational readiness program, and would like to explore how to incorporate fire hazard mapping and participatory mapping with other agencies, especially after having demonstrated the use of the following proposed OpenStreetMap tags to identify potentially dangerous areas in their respective areas of responsibilities and use in standard GIS software:
hazard:authority = Bureau of Fire Protection hazard:type=fire hazard:risk= (high | very_high | extreme)
P.S. I will update this post when I get copies of the photos we can share. I, again, forgot to take my own pictures.
I am visiting General Santos City for some research but, unexpectedly, we completed our tasks much earlier. I had lots of time to kill, and reached to a local university (Notre Dame of Dadiangas) and offered to conduct a workshop on FOSS/Participatory Mapping for their community. Unfortunately, because of the short notice, and their other commitments they were unable to accommodate the request.
Diligent RAs made quick work of our tasks
Two blocks down from the university, is the headquarters of the city's Fire Department, and I decided to drop by, to say hello, hoping for some chit-chat, and maybe some data as well.
General Santos City's Fire Department https://osm.org/go/4sJFDJKXl?m=
Luckily, not only did were they willing to chat, they were even willing to work and map their assets - pronto!

That same afternoon, we got to complete the map of their fire hydrant network, including the location of auxiliary companies in General Santos City :
The General Santos City Fire-fighting Assets map. Left, before our map jam. Right, our output that afternoon.
After jamming with them, they invited me to join a planned field inspection for the following morning. I willingly accepted, and offered to demonstrate how Mapillary works, and how they may utilize them in their work flow.
Searching for ~~Nemo~~ hydrants. Their inventory report include a description of the location, but they're not what we saw on the ground - weed covered hydrants, missing markers, or buried in concrete! Also, we had problems finding street names, and other basic information, so we had to stop a few times, asking directions from local residents.
We collected imagery using Mapillary, and used them to tag the hydrants we found.
As for me, well, I got to ride a fire truck for the first time - and even got to don a firefighter's helmet. :grinning:
Six thumbs up for a productive morning with the local smoke-eaters. :fire_engine: :man_firefighter: :woman_firefighter:
Kudos to the friendly and enthusiastic crew of the General Santos City Fire Office.
reposted from MapAmore's Events repo
Thank you to all the participants who spent their Saturday afternoon with us, mapping the city of San Juan, over Independence day weekend. We're also thankful to San Juan City (and their DRRMO) for making the venue and facilities available.
And a shout out to Mapillary, for the refreshments.
This is the second city mapa-thon, and a follow-up activity to enhance the Free/Open data collection of the city of San Juan, and to complete the leftover tasks from the last mapa-thon, chiefly working in the second district of the city:
Shown here are the 21 barangays of the city, using the MapCraft tasking manager Data © OpenStreetMap contributors (ODbL); Image © MapCraft

Evacuation Shelters and
The designated evacuation shelters in the city are re-purposed facilities made for a different, primary purpose. Hence, we adopted a tagging convention initiated by the OSM-tw community, and now widely used in Taiwan, where the prefix tag
emergency: is added to the secondary tags related to emergency and DRR mapping.
For example, a sports centre that's been designated by the village council as an evacuation shelter for displaced persons, may then be tagged, as appropriate, as follows,:
name=Palakasan Covered Court
During non-emergencies, they function as originally intended - a sports center, but are re-purposed as shelters during emergencies. Would they have been dedicated shelters, the
emergency: prefix are dropped and the are simply tagged as:
name=Palakasan Evacuation Shelter
We've completely mapped the evacuation centers, barangay halls of the city, except for one barangay where no data was available. Click to view data and details on Overpass Turbo. © OpenStreetMap contributors.
The DRRMO was unable to provide the capacity data of the facilities, and that would've been useful to have.
Fire Stations and Hydrants
Participants from the Bureau of Fire Protection (their back to the camera): Inspector Antonio (right), and Officer Aquino, listen intently to Mr. Rally de Leon's (facing the camera) lightning talk, during the break.
The Bureau of Fire Protection (BFP) is the country's national agency (under the Department of Interior) responsible for implementing national policies related to fire fighting and prevention. Two personnel from their local office participated in the mapa-thon. They expressed their plans to pursue the validation and mapping of the city's fire-fighting resources.

Blitz Decks & Pizza
To add some fun and variation to our mapa-thon, we introduced a longer break period coupled with Blitz Decks. The floor was made available to anyone who'd like to present about anything (hopefully, Free/Open Source or Geo-related, but any topics is welcome (except religion, and politics).
OSM and Project NOAH
Here's Dianne, getting ready for her talk about how Project NOAH uses OSM - fueled by pizza and soda, courtesy of our friends from Mapillary - yay!
Neighborhood Mapping and Addressing
Rally de Leon talks about his experience in neighborhood mapping and the importance of addressing.
Mapping Hydrants in OSM, and how we got our first hydrants, and how El Deposito figured in our history, by yours truly.
All these data sets are now available from OpenStreetMap. Thank you to everyone who made this possible. We're looking forward to our next mapa-thon!
I enjoyed hearing the different viewpoints coming from people who came to try out mapping for the first time:
Kids to remind us to have fun while we're working. :)
Again, we failed to take a proper group photo. :crying_cat_face: Everyone's too busy mapping, or helping out.
I just finished reading Side-by-side images expose a glitch in Google’s maps which highlights some shortcomings of Google Maps (GM), which the writer call as "glitches".
I find that amusing because I often hear the same assertions against OSM. Immediately, I wondered how the OSM community is faring in those same areas:
Morro dos Prazeres
Nomgon, Ömnögovi Province, Gobi
So, is OSM, at large - and in those specific areas, doing any better than GM, right now? No, not really. Not yet.
We all know that it's the local community that makes the real difference, and it's unlikely there's any active ones there, hence the very bare coverage.
In the long run, as soon as these areas do get better data, the Open nature of the data license provided by OSM makes it superior to what GM may offer.
While the article decries about the lack of data, and call these communities "invisible" from GM (and their end-users.) The writer may not have known why OSM is the platform of choice by many humanitarian organizations.
When communities recognize the need to become "visible" by being depicted in public maps, to have a voice in governance, they are very welcome to do so in OSM. The community mapping efforts of the Kibera project in Nairobi, Kenya, its empowerment of the community that's called the largest slum in Africa proves that. And that effort is happening in many nooks and corners all over the world. External actors could introduce OSM mapping, but it can only be sustained by an active community of contributors and end-users.

As a commercial enterprise, GM cannot be faulted for their underlying (commercial) reasons for doing things.
In OSM, I'd like to think we map simply because we can.
Keeping up-to-date, relevant maps, is a challenge for many organizations, especially if they don't have the in-house capacity, or the resources to systematically maintain geo-spatial datasets that are useful across multiple departments or end-users. This is not an uncommon scenario in many municipal governments in the Philippines.
Over the last several months, the MapAm❤re Initiative in San Juan, have been collaborating with local actors and promoting Free software, especially OpenStreetMap, to communities who are seeking to make the most of what's possible with Open data.
Last Monday, we've successfully concluded a City Mapa-thon for DRR to help the local government, in particular the City Disaster Risk Reduction Management Office in creating and updating the map features necessary for their risk reduction and resiliency programs.
87% of the people who registered for the mapa-thon made it to event. Thank you to everyone who chose to spend their Monday afternoon with us, helping out the city of San Juan.
Thank you, too to the City DRRMO, for hosting the event and making their facilities available for the volunteers.
A big thank you to our generous benefactors who sponsored the pizza and drinks. And a shout-out to Mapillary, for the swags we raffled after the mapa-thon. Maraming salamat!

The mapa-thon achieved partial completion of the update/identification of barangay-level DRR facilities (mostly in the first district, prioritized because of population density). The mapa-thon participants were mostly newcomers and beginners to OSM editing, and we invested a significant part of the activity to training them how to use the iD editor. Meanwhile, and apart from coaching the learners, the advance mappers also took part in fixing https://github.com/OSMPH/papercut_fix/issues/13.
We also made use of the photos we captured during our Mapillary run early last month. It was a useful reference for mappers during validation, and when trying to determine location or features.
Mapa-thon Part Deux?
We've proposed a possible follow-up mapa-thon on 10th June, hopefully with the same group (to recoup our training investment) before the new school term starts and finally finish working on the remaining barangays. See: https://github.com/mapamore/events/issues/7
Data © OpenStreetMap contributors (ODbL); Image © MapCraft
The training segment is often mentioned as the least enjoyable portion of the activity, but is a necessary :imp:. We can only strive to make it less boring, and more engaging. It's proper training that makes it possible to avoid things like the screen grab below from happening in the first place, but then there's Murphy's Law. So experienced mappers also play a very important role in validation to ensure quality edits, and in coaching, to show them the ropes.

With Open data, other applications can add value to the data that mappers contribute and with the OpenStreetMap database acting as the primary repository of the same data. Update once, and make the updates available for everyone else.
The map data may be used off-line, on mobile devices. This OsmAnd screen shot shows the same area, with fire hydrants shown. Useful for fire fighters and emergency responders.
This Umap shows city hydrants that is retrieved dynamically from the OpenStreetMap database. Orange dots represent high-pressure hdyrants.

Ala eh OSM - the Basic Mapping Workshop
Last week, a few OpenStreetMap advocates from Metro Manila made a trip to Batangas for a training engagement with the Bayanihan Mapping Workshop co-organized by MapPH and their partners. OSMph has had extensive engagements with some of MapPH efforts in the past years, and we continue to work with them in common spaces where we can collaborate.
The workshop was attended by over fifty enthusiastic participants, mostly from the respective Disaster Risk Reduction Management (DRRM) office, or the Planning and Development offices of the local government units within the Taal Volcano Protected Landscape (TVPL), about a third of the municipalities of Batangas province:
MapPH's principal partners - Pusod, Inc. (an NGO that supports sustainable tourism within communities they work in; they've established the Taal Lake Conservation Center in the town of Mataas na Kahoy ), the TVPL Superintendent's Office (under the national Department of Environment and Natural Resources ), and the activity's host, the Batangas State University - also sent their representatives to participate in the workshop.
As with our usual program for introductory courses, the iD editor was used, and the training put special emphasis on how to map and match features and geometries properly, tag them appropriately, and with practical mapping exercises, show how they can use them in their particular mapping efforts after they return to their communities.
The participants were trained in a number of practical field survey tools and techniques, including: Field Papers, SatNavs, and photo-mapping.
Field Papers has always been a long-time favorite for low-tech, low-cost approaches for mapping communities effectively. For collecting track logs, theoretical SatNav topics, practical examples, and alternatives were discussed, as SatNav devices are not commonly available to participants.
And with the ubiquity of SmartPhones, Mapillary was introduced as a photo-mapping tool for collecting fresh, street-level imagery, when aerial imagery is inadequate, out-dated, or non-existent.
Here's one of the teams during the field survey, using Field Papers.

The local Mapillary Ambassador is caught on camera; leading another survey team and photo-mapping with the app:
Check out these street-level photos captured using the Mapillary smartphone app by a Talisay DRRMO staffer from another team.
After the field survey, the participants uploaded the data they collected and used them to update the map of the area their team was assigned for the exercise:
The teams continued with arm-chair mapping, and we also discussed other topics on how to utilize OSM data further. Some participants got lucky with smartphone holders given away, which they can use in their cars and bicycles, courtesy of Mapillary, like this one here:

There are a number of diligent mappers in the Batangas area (@TagaSanPedroAko is a conscientious mapper that comes to mind), and also because of the previous mapping activities led by UP-NOAH (erst Project NOAH), substantial building footprints has been traced from current satellite imagery, as well.
I hope that we also succeeded in conveying the value of Free and Open data, and how such data, and platforms like OpenStreetMap, contribute towards other public projects (like UP Noah); and, that their efforts to produce better community maps, also shape and improve regional and national maps.
We'd like to see these awesome OSM contributors - new and old alike - continue their mapping efforts in the spirit of our bayanihan tradition, and enrich the local geodatabase in close cooperation, with inspiring details and relevant features that their communities find valuable and important.
Remote mapping is important for baseline data but relies solely on available imagery, and can only do so much -- local knowledge and local action trumps that. In the future, we'd prefer to see more mapping parties organized from, and led by the local community.
Did you participate in the workshop? We welcome your feedback, so we can do better next time.
