Of being a part of the OSM-PH community

Posted by feyeandal on 27 June 2021 in English (English). Last updated on 28 June 2021.

Last September 2020, the OSM-Philippines community released the Call to Correct Narratives about Geospatial Work [in the Philippines]. We’re provided with an opportunity to share our own narratives and showcase the local community’s initiatives through a documentary-video produced by Amazon Web Services – Philippines.


I am especially thankful for the chance given to me by the local community to represent YouthMappers and to share my journey as a volunteer for OSM-Philippines in this documentary-video. My interest and passion for OSM and open mapping rose out of my deep admiration over my co-volunteers in OSM-PH, who have immeasurable passion for open mapping and for serving the local communities. My active engagement in this community has given me a lot of opportunities to meet other people and to learn something new every day. It has also helped me hone my technical knowledge and skills in mapping, gain my confidence and build my credibility to make a good impact to the community, and direct me towards the consciousness of building a quality data to OSM.

Years after initially being a part of the local community, I realized that the need for serving the communities through providing them with accurate and updated data still matters, but the joy of working with the people we meet help sustain us (volunteers) in continuing our volunteer efforts. I am glad that I am surrounded by people who care deeply about their work and service to the community and challenge me to be the best that I could be.

Through the OSM-PH community, I am humbly reminded of the importance of community and of coming together to serve the communities in any way possible. I know, for sure, that this is what binds the OSM-PH community together and stronger – something that cannot be taken away from us.

I hope that we are able to inspire other local OSM and geospatial communities to capture what is really happening on the ground and to share their own narratives through their lenses.

Cheers, Feye

Last 20 February, I hosted an OpenStreetMap workshop and Mapathon with the local YouthMappers chapters in the Philippines. It was attended by the members and volunteers from UP Resilience Institute Youth Mappers, FEU - Alabang ACM Chapter, and JPCS - National University. Together, we mapped San Ignacio, Tarlac. This was a great avenue for the students to meet and get together and help the local government of San Ignacio and support MapBeks’ initiative #UNMAPPED2021

Taken 20 February, PH YouthMappers unite to map San Ignacia, Tarlac

From this activity, we were able to add and validate a total of 2,146 buildings. We are hoping to add more and validate more data in the coming months!

I am also happy to share with you that University of Makati - Computer Society is the 5th local YouthMappers chapter in the Philippines! I am aiming to recruit more organizations to join the OSM community and YouthMappers network from Visayas and Mindanao islands in PH.


Cheers, Feye, YouthMappers Regional Ambassador

2020 is coming to an end and we are all taking a moment to appreciate on the past twelve months. The HOT-Philippines Mapping Team members are hard at work to provide the best quality of data in our field operations and our remote mapping and training activities. To help you look back, we prepared a year-end report that summarizes our accomplishment for the year.

PhilAWARE Project

HOT-Philippines started the PhilAWARE Project last July 2019 which is a local installation of DisasterAWARE, a disaster risk reduction and integrated early warning and decision support system that also incorporates many data layers form OpenStreetMap.

Part of the activities of the project included remote mapping in the province of Pampanga and municipalities of Quezon City and Marikina City. Remote mapping and validation activities for Pampanga and Quezon City have been completed with the help of volunteers, organizations, partners, and other stakeholders while Marikina City is still in progress.

Aside from the remote activities, we also began collecting the data from the ground in the municipalities of Pampanga last August. Our field operations was made possible through the support of the local government offices and volunteers in Pampanga despite the restrictions of COVID-19.


Alongside the PhilAWARE Project, we supported OSM Philippines’ OSMaPaaralan Project which is an initiative to collaboratively map public schools (paaralan) in the Philippines using OpenStreetMap. Our team is validating location of schools in Pampanga and updating information related to emergencies. If you want to contribute and learn more, head over to the MapRoulette task and help OSM-PH complete the project!

Mapping in a Pandemic

The pandemic has a large impact on our remote and field operations. Our team has encountered a lot of challenges such as postponing and slowing down of field mapping activities because of sudden lockdowns and surge of active COVID cases, resigning staff due to COVID-19 safety threat as well as self-isolation caused by experiencing COVID-19-like symptoms but we were still able to pull them through. [We were also able to make a documentary on how COVID-19 remapped the reality and presented them during the 2nd day of Pista Ng Mapa. Video available online soon.]

While being affected by the pandemic, we are part of the UP Resilience Institute’s initiative to end COVID-19 (#endcov). UP Resilience Institute collaborated with HOT-PH in mapping and validating the building footprints of Quezon City. The data were used by UPRI to develop a data-driven analysis and recommeendation to the local government unit of Quezon City for the city’s pandemic response. [We created a poster about this initiative and participated at the State of the Map 2020’s Poster Exhibit].

See photos below for the summary of our output for 2020:







We would like to thank everyone for the continued contribution and support in our project. We hope to see you again next year!


HOTPH Mapping Team

As of 21 September, the mapping and validation tasks for the campaign #PhilAWARE - #MAPampanga in the Tasking Manager have been officially completed. Quezon City and Pampanga are the two pilot areas for the #PhilAWARE project. Quezon City tasks were also completed on June 2020, as part of the #endcov initiative of HOT-PH and UP Resilience Institute.

OSM building footprints and roads in Pampanga from January to September 2020

Building footprint count and road length (in in Pampanga from January to September 2020

The #MAPampanga remote mapping activities started last February 2020, days before the #MAPampanga event held at Thinking Machines Data Science office in Taguig City. The completion of the projects in the Tasking Manager was made possible through the help of several organizations and individuals. We conducted series of in-person and online mapathons with various student organizations and corporate partners, government agencies, and the general public to engage with more volunteers and build quality mappers.

There has been an increase of ~933.41% in the building count while ~63.99% in the road length through the #MAPampanga mapping initiatives. A total number of 1,754 unique contributors has also been recorded.

Prior to the HOT Philippines activities in Pampanga, OSM Philippines and the local government units of Pampanga (Guagua, Lubao, and Candaba) have been contributing to improving their map in OpenStreetMap.

While the remote mapping and validation tasks have been concluded, we still have a long way to go. The HOT-PH Field Mapping Team based in Pampanga started the field mapping operations last August for the municipalities in Pampanga to collect critical lifeline infrastructures data. Aside from field mapping, the HOT-PH Training Team also started training and building the capacity of the local government units and volunteers on using OpenStreetMap.

We would like to thank everyone who contributed to #MAPampanga and #PhilAWARE!

If you have a bunch of geospatial data (e.g. buildings, banks, hospitals, schools, etc.) and you want to ensure that the tags/attributes on each of your data is “complete” before uploading it to OSM, you may want to check its data completeness first. To assess whether your data is “complete”, make sure you have a list of tags that you expect from your data.

Sample houses data opened in JOSM

I wrote a simple python script to check the data completeness of a specific dataset.

Generally, the script opens and reads a geojson file and uses a json schema that allows us to annotate and validate every feature of the geojson file. The defined json schema is the set of attributes you expect from your data. If all of these are met, then the object is tagged as valid (complete), otherwise it is tagged as invalid (incomplete). The output from the function is then saved to a new csv file.

Sample schema (groups of tags) I set to assess the completeness of the input file

In my defined schema, each of the key has a type requirement (string, number/value) and a defined set of expected values. I also added a required keyword to indicate the required fields for a specific feature to be tagged as valid/complete.

Sample output from the script: indicating which objects are valid or invalid

From the output file, you can now easily check which nodes need to be fixed! Now, let’s take a quick look at node #7 which turned out to be invalid. You may convert your geojson file to a csv format file so you can easily visualize the data (into a table form).

Node 7 tagged as invalid

As seen from the screenshot, there is a missing value for the key building. Since from the json schema in the script, I set all fields as required, no column must have null value. Thus, node #7 was tagged as invalid.

Node 8 tagged as invalid

Another example here is that the value for the building:levels is in string format. As I set the building:levels format to number/value in the json schema, this node was tagged as invalid.

So, there! I hope you find this script also useful for your validation.

In cooperation with the UP Resilience Institute (UPRI), the Humanitarian OpenStreetMap Team (HOT) – Philippines has completely mapped and validated building footprints in Quezon City, Metro Manila on OpenStreetMap as part of the response we are doing to end COVID-19 (#endcov). Quezon City is one of the most densely populated and hardest hit municipalities in the Philippines by COVID-19. The OSM building footprints were used by UPRI to develop a data-driven analysis and recommendation to the local government unit of Quezon City for the city’s pandemic response. This is also part of the PhilAWARE project to map the critical infrastructures across the Philippines.

The mapping initiative started on 20 April 2020 through the HOT’s Tasking Manager (#8385, #8386).

Changesets and contributions in Quezon City from 21 April to 11 May

Through the help of 644 contributors around the world, 317,325 building footprints were added and validated to OSM in 62 days.

In behalf of HOT-Philippines, I would like to take this opportunity to thank our amazing mappers, validators, and volunteers who tirelessly work on creating and maintaining the data quality in OSM that would surely help the local communities in our campaign to #endcov.

Check out all the posters at the SoTM website!

Lately, I’ve been sitting with emptiness, constantly battling with my depression and anxiety, yet fighting to exist in my everyday life. I feel like my pursuit for finding meaning and purpose in life that transcends change never ends. And as I live my life, I tend to look for something positive hoping to fill that void. Well, I guess this is what #existentialcrisis does to me.

Luckily, I got a partial support to attend SoTM and HOT Summit in Heidelberg, Germany. Of course, I do not want to miss this great opportunity. I haven’t attended a global SoTM conference before, and this news gives me another hope in life or at least something to look forward to. And maybe, just maybe, this is the ‘something’ I’ve been looking and waiting for. The ‘something’ that can numb the perpetual feeling of emptiness.

And since I only applied for partial support from SoTM (only the accommodation fees and conference tickets were covered), I need to ask my employer to cover the remaining travel expenses I have. Unfortunately, I was informed that there are no available international travel funds for non-contractuals like me. Sucks, right? The fact that UP couldn’t support me keeps me up at night and eats at my soul again. But I do not want to give this opportunity up. No, not yet. And so I took my chances and talked to some people in the OSM Philippines community about my dilemma. Although they also couldn’t provide financial assistance for me, I am still grateful as they have shown overflowing moral support to me, especially when they learned I got nominated for the OSM Awards 2019.

I don’t want to give this up, as I have been eyeing to attend global SoTM since 2015. I was left with nothing but to support myself financially in this journey. I realized that nothing really comes easy, and so I need to take risks, even if it costs me a lot.

Not a day goes by where I don’t get panic and anxiety attacks thinking about the SoTM conference. As scholars of State of the Map 2019, we were asked to give a lightning talk of any topic we’d want to talk about. Oh, this is the first time I’d be doing an oral presentation in an international conference abroad, so all the anxieties are building up inside me as the day of my presentation gets closer.

Amidst all the chaos going on inside my head, I reminded myself to stay calm and take it easy. I decided to present one of the works UP Resilience Institute’s been doing since 2016. I gave a lightning talk on “Using OpenStreetMap Building Footprints Data for Population Distribution Model: A Case Study in Cavite, Philippines”. It was a challenge for me to present all our work – from methodology to results, all in 5 minutes, so I tried my best to share the learnings and challenges we’ve encountered as concise as possible. Good thing my friends from OSM-Philippines were there during my presentation to support me.

The best favor I did for myself during the conference was to try being a social butterfly instead of staying as a wallflower. I began to come out of my introverted shell and engage with people – and it was the greatest part of my SoTM journey. It was really nice meeting the people from the OSM community all over the world – the people I only encounter online! It’s warming to engage with people with the same heart and passion for OSM.

I was also very delighted to meet Tim Sutton (!!!!), one of the developers of InaSAFE. As a heavy user of InaSAFE in the Philippines, I got goosebumps all over me when I met and talk with him! Too bad I wasn’t able to take a selfie with him!

Of course, meeting the Humanitarian OpenStreetMap Team (HOT) in person has been fun! Although I have already met a couple of them during State of the Map-Asia last 2016, it’s always thrilling to see them.

And who would have thought that I will get close to my roommates @tshedy, and @Fanevajanahary, who are both champion mappers in Africa (Lesotho and Madagascar), and Ate @jenjereren, an advocate and mom mapper. They are easy to be with, and I also got inspired by the works they’ve been doing in their respective fields. Check out #MapLesotho!

Big thanks to OSM Foundation for the scholarship grant and the opportunity you have provided us. Special thanks to Dorothea Kazzazi for guiding the scholars from the beginning up until the conference concludes.

It has been a week since the conference. None of these would have happened if I did not take the risk. Maybe this was the ‘something’ I’ve been searching for to be able to fill that emptiness inside me, even for a moment. It was truly a risk but it’s a risk I’m glad I took. Thank you to everyone, especially OSM Foundation who made my SoTM journey worthwhile. :)


In celebration of the Geography Awareness Week, Grab, Map the Philippines and OpenStreetMap Philippines co-organized a mapping party to teach people how to map, and meet other mappers. It was held at Grab PH’s headquarters in Makati and was attended by volunteers, students, government employees, NGO workers, and Grab personnel.


Celina Agaton talked about the objectives of the mapping party and also introduced her organization, Map the Philippines.

It was followed by an introduction to OSM and Tasking Manager by David Garcia.


Lastly, I gave a brief introduction about UP NOAH and UP Resilience Institute. I also introduced the mapping tasks that will be used for the mapathon. See image below.



We used the hashtag #osmgeoweekPH to track the edits by the participants. Here are the statistics:


We also gave three major awards for the users who have contributed the most during the mapathon.

Huge thanks to Grab, MapPH, and OSMPH for organizing this activity!

My FOSS4G - Boston Experience

Posted by feyeandal on 25 September 2017 in English (English).

Last August 16-19, 2017, I attended the International Conference For FOSS4G held in Boston, Massachussets, USA. It is an annual recurring global event hosted by OSGeo. The FOSS4G (Free and Open-Source Software for Geospatial) conference is the largest global gathering focused on open source geospatial software. It brings together developers, users, decision-makers, and observers from a broad spectrum of organizations and fields of operation. FOSS4G I was one of the ten travel grant awardees under the OSGeo Travel Grant Programme (TGP). Through the financial support from OSGeo and UP NOAH have provided me, I was able to attend FOSS4G. It has given me the opportunity to gain knowledge on the on-going open-source projects around the world. My participation from the conference has provided me direct access to presentations from many organizations within the open-source community, allowing me to gain valuable information about what other projects are all about and where they are focusing their efforts. Attending this conference has provided me with opportunity to learn more about the latest free and open-source software for geospatial technologies and developments, but also increase visibility for the research organization I am working for, UP NOAH. FOSS4G

Favorite Sessions

  1. Breaking Up is Easy to Do: Leaving ESRI Behind for QGIS – A Case Study FOSS4G This, perhaps, was one of my favorite sessions. Alex Cohn discussed the reasons why their organization made a transition from using ArcGIS to QGIS and explained the impacts of this transition on their everyday operations for two years.

  2. It’s About People: Putting the ‘Community’ in ‘Open Data Community’ FOSS4G This session was basically focused on solutions and challenges to empowering collaboration within the community using the MapStory project. MapStory is a free and open-source platform for crowd-sourcing global spaciotemporal data. Since it is a participation-focused open data platform, it emphasizes and revolves around the contribution of the global community.

  3. Lastly, I enjoyed listening to the talk of Steven Feldman about Fake Maps. Obviously, it was telling us about the power of maps that may mislead people through the message of the map intentionally, or through a lack of understanding. It was a fun and chill talk by Steven and I am sure that everyone loved it.

The Keynote

There were 5 keynotes for this year’s conference and I must say that one really stood out – the keynote from THE Richard Stallman. Dr. Richard Stallman launched the free software movement in 1983 and started the development of the GNU operating system in 1984. It is a free software – everyone has the freedom to copy it and redistribute it, with or without changes. It was a pretty long keynote though, but surely leaves discussion within the community about what an open-source software really is.

Wrap Up

Attending FOSS4G was quite rewarding for me. It is an opportunity that should not be missed. It was also great to meet the geo-geeks and learn so much from them.

I would want to take this chance to thank everyone involved in making this conference possible.

Next year, it will be held in Tanzania in August, and I hope to be there!

May the FOSS be with you!

Project NOAH has finished mapping the building footprints of ISAIAH’s 15 target provinces and an additional province for “good will”. The completion of its mapping initiative was made possible through the help of several organizations and individuals such as MAVC program, Aurora Provincial Disaster Risk Reduction and Management Office, UP Rockhounds, Geographic Society of the University of the Philippines (GSUP), Eastern Samar State University, Eastern Visayas State University, UP NSTP-CWTS program, and OSM-Philippines contributors. NOAH finished mapping the building exposure data of Abra, Aurora, Bataan, Batangas, Biliran, Camiguin, Cavite, Eastern Samar, Ilocos Norte, Ilocos Sur, Leyte, Misamis Oriental, Northern Samar, Samar, Southern Leyte, and Zambales. NOAH also mapped the building footprints of Pateros and Taguig City of Metro Manila.

Stats Report

The building exposure data is essential in calculating the disaster risk of the communities. Part of the ISAIAH’s objectives is the completion of risk profiles of the 15 target provinces. With this data, local government units can formulate their disaster risk reduction and management plans and make informed decisions when they are threatened by natural hazards.

The translated building footprint data mapped by NOAH through OSM is integrated into the WebSAFE application of Project NOAH. It is a web and mobile-based impact assessment tool used to identify the number of affected people and structures when a hazard scenario (e.g. flood, landslide, or storm surge) hits a certain area. WebSAFE can help us identify the buildings exposed in hazardous area that is useful in disaster preparedness activities, especially for preemptive evacuation.

Thank you for helping us in mapping the Philippines through OpenStreetMap!


As a part of Project NOAH’s mapping initiative, a team was sent to Region 1 for another installment of the OSM and Capacity Assessment Workshop. From 6-13 November 2016, planning and preparation for the workshop proper were done. Project NOAH sent a team with six personnel, who served as lecturers/speakers and proctors for the said activity.


The workshops’ goal is to engage Local Government Unit officials in helping Project NOAH build a disaster resilient Philippines. Since NOAH has long embraced public participation to improve emergency response and disaster mitigation throughout the country, it is but proper to take this crowdsourced and collaborative effort to the ground, thus, to the LGUs’ jurisdiction.

The schedule of the workshop was as follows:

November 8, 2016 in La Union with 57 participants (La Union Provincial Hall, San Fernando, La Union)

November 10, 2016 in Ilocos Sur with 57 participants (Baluarte Auditorium, Vigan, Ilocos Sur)

November 11, 2016 in Ilocos Norte 43 participants (Liga ng mga Barangay Office, Town Plaza, Bacarra, Ilocos Norte)

OpenStreetMap Workshop

The workshop is an introduction to the OpenStreetMap platform; it focuses on the critical facilities mapping on OSM using Java OpenStreetMap (JOSM). Many of the participants already have knowledge on the use of Geographic Information System softwares like QGIS since they come from DRR, planning, and engineering offices.


Participants were given time to digitize the critical facilities related to disaster risk reduction and management on OSM. They were introduced in the use of mobile mapping field data collection applications through the use of Smartphone applications such as OsmAnd for Android and Go Map!! for iOS. They were also taught on using Field Papers, and extracting data from OSM for use in GIS softwares.


Four months before the target workshop dates, the Project NOAH sent and forwarded emails inviting the DRRM Officers of Ilocos Norte, Ilocos Sur, and La Union through the provinces’ governors.

Indeed, DRRM Officers, and even officials from other local government agencies (PNP, BFP, DOH, DILG, DSWD, among others) were present in each workshop. All of which helped in identifying their communities’ critical facilities, presented their Comprehensive Landuse Plans (CLUP), and in turn pinpointed their areas’ imminent risks.

Through the activity, NOAH was able to help harness the geographical contributions of the volunteers/participants who were engaging enough that they helped Project NOAH in looking for solutions heavily involved damage assessment and analysis activities before, during, and after large-scale emergencies.

Problems Encountered

Most of the problems encountered were technical, just as:

  • Poor internet connection

  • Compatibility of participants’ laptop

  • Printer jammed during the Ilocos Sur workshop

However, NOAH staffs were able to address these issues efficiently and effectively and the workshops went well.

OpenStreetMap contributors, through the initiative of ISAIAH (Integrated Scenario-based Assessment of Impacts and Hazards) component under DOST - Project NOAH (Nationwide Operational Assessment of Hazards), have recently completed mapping the building footprints of Cavite.


One of the objectives of ISAIAH is to map the exposure elements such as buildings and critical facilities. Identifying the critical facilities such as schools, hospitals, and government offices, and other infrastructures will be essential in determining the areas vulnerable to disasters and can be used as a starting point in reducing disaster risk. All of these data will be used in improving community disaster management before, during and after emergencies. This initiative involves a collaborative partnership with the OpenStreetMap community.

Last March to April, Project NOAH conducted a series of OpenStreetMap training to its staff to digitize the building footprints in the selected provinces in the Philippines using the available imagery from Bing and MapBox. The provinces were selected according to the available imagery, land area and population of the provinces, and the available population data we have from the Philippine Statistics Authority as of 2010. Accordingly, Project NOAH created a mapping task on the HOT Tasking Manager for the province of Cavite. Since then, Project NOAH staff and OSM community started contributing to the mapping task.

Cavite Tasking Manager

As of June 28, the mapping task for Cavite is 100% complete and 18% validated. This mapping initiative helped increase the number of building footprints in Cavite from 110,506 to 631,825.

Below is the image of the downloaded building footprints in Cavite as of June 28.

Building footprints mapped in Cavite after NOAH initiative

You may view the map comparison of before-and-after edits here.

The translated building footprints data from OpenStreetMap are being utilized in one of Project NOAH tools, the WebSAFE application. It is used as an impact assessment tool for end-users to be able to readily identify the number of affected people and buildings in case a hazard scenario like flood affected a certain area. Using this tool, local government units can easily identify how many relief goods are needed to be allocated when a severe weather event happens.

OpenStreetMap Workshop in Bogo, Cebu

Posted by feyeandal on 23 February 2016 in English (English). Last updated on 3 March 2016.

Last February 9-11, the Philippine Red Cross (PRC) and the Croix-Rouge Francaise hosted a 3-day OpenStreetMap workshop in Bogo, Cebu, as part of their Northern Cebu Risk Mapping project. This participatory project aims to improve the base geogspatial data coverage of Northern Cebu for use in disaster response, climate adaptation, risk mitigation, and support other humanitarian initiatives. It was attended by local government staff from Bantayan, Daanbatayan Island, Bogo, and local PRC volunteers.

  • Day 1: Introduction and Basic Editing on OSM

Day 1 consisted of an introduction to the PRC project and a general overview of OSM and OSM-Philippines. A presentation of the objectives of the data collection and an introduction to the mapping components were also given. Before the discussion of the OSM website, we had an activity wherein participants were asked to draw their vicinity map and explain their maps afterwards.

One map caught our attention, though… it’s 3D!

  • Day 2: Field Data Collection Tools and Tasking Manager

On the second day of the workshop, participants were taught how to use some tools for field data collection like Field Papers, GPS handheld devices and OsmAnd for smart phones.

Luckily, we were given an access to Digital Globe’s WorldView-2 satellite images taken on February 15, 2015. These images were humbly provided by the MapGive Project, through Celina Agaton’s initiative Map the Philippines. The image is orthorectified for terrain corrected geographic precision. Furthermore, the image has been contrast stretched using a custom stretch and processed into a Tiled Map Service (TMS) for performance. It allows the participants to use the imagery and digitize features on the map.

Tasking Manager:

We set up a Tasking Manager for this workshop. You may access the task here.

Statistics of the Bogo Tasking Manager; As of February 19, 18% of the mapping tasks was done. Long way to go! Statistics of the Bogo Tasking Manager; As of Feb. 19, 18% was done. Long way to go!

  • Day 3: Fieldwork and Quality Editing

The last day of the training involved an actual field data collection in Barangay Libertad and data processing from the field.
