Posted by farhadGuli on 25 November 2017 in English (English)

I was Google map user, its been 5 years I work for it making new place names and lining roads and now im Local Guided user , but Google map has an old satellite version comes from 2004 especially in my town ! And recentrly stopped for making roads ! , Now I'm OSM user since 2014 but the things I noticed is the acceptable for my changes when you make new place and street OSM accept it quickly, not like Google map it takes 2 week for accepting or not. Im Glad to help with you OSM. And sorry if my English is bad :)

A user study to understand human cognition influence on data classification quality

Posted by grass_and_green on 25 November 2017 in English (English)

Dear participants,

Thank you for helping science and supporting voluntary geographic contents. The contents which have been exclusively collected by voluntary efforts. In these contents, public with local knowledge is the main source of information. Thus, we are (as a computer scientist) concerning with human cognition influence on data classification. Human perceives things differently.

For example, regarding landuse/landcover classification, we could agree on that a parcel of land is covered by grass or water which is an abstract level of classification. However, whether this parcel is a park, a garden, a cemetery, or even a golf court might be perceived differently. Whether this water body is a pond, a lake or a reservoir likely requires finer measures, geographic knowledge, and particular expertise.

Therefore, we developed a study to understand more about how people perceive geographic contents remotely. The study aims to:

  • find out human capabilities to provide landuse data.
  • understand the influence of classification mechanism and schema on data quality.
  • study human behaviors in providing voluntary data, and
  • emphasis challenges of data classification in voluntary contents.

The study takes about 25-30 min. We do not collect any personally identifiable information. Thank you again for your time and your contribution. To participate in the study press here

Don't hesitate to contact me for further comments and feedbacks.

Best regards,

OSMF Board election manifesto

Posted by pnorman on 25 November 2017 in English (English)

I'm Paul Norman, OSM user pnorman. I've been mapping since 2010, and involved in other facets of OpenStreetMap since 2011. For the last three years, I’ve been on the OSMF board, and am running for re-election. During my time I’ve seen the board grow in productivity, the finances become more stable, and us make good strides in transparency.

Outside the board, I’m also involved with the OSMF on the Data Working Group, License Working Group, and Membership Working Group. As a software developer, I’m a maintainer of OpenStreetMap Carto and osm2pgsql, as well as being involved in many parts of rendering toolchain.

In my work life I’m an independent software developer, working on map rendering, cartography, and PostGIS for clients. My main contract right now is with Wikimedia Foundation, as the developer on their maps team. In the past I’ve worked for CartoDB, Mapquest, and other companies.

Looking back at what I put in my 2014 manifesto, I’m moderately pleased with the progress we’ve made in both transparency and productive board meetings. Neither are perfect, but they’re a vast improvement over three years. Overall, I’m satisfied with my time on the board. I accomplished some of what I wanted to, and think my manifesto desires were realistic.

My concerns are now

Conflicts of interest

6/7 board members work with OSM somehow in their jobs. This includes four with employers who sell services based on OSM data and can easily run into conflicts of interest. We are not managing this, which might have worked in the past, but is not a good practice. There’s stuff we need to set up like having an email discussion out of sight of the people with conflicts. Right now it’s considered acceptable for a board member to take part in discussions where they have a conflict of interest. Clear rules would also protect board members from pressure from their employer.

On a working group whenever there’s occasionally been an intersection between my work and the WG. In these cases I’ve removed myself from the discussion. This is what we should all be doing on the board.

Unfortunately, as someone who is paid to work with OSM data, I run into conflicts of interest myself, but in practice, I have less than most with the nature of who I work for.

Support, but not control

The job of the OSMF board is to support the mappers building the map, but not control them. I worry we are losing sight of that, and people increasingly want to exert control and consider the mappers secondary. We need to protect the ability for people to independently do activities, even if it’s not something the board agrees with.

Volunteer capacity

A lack of volunteers was an issue when I ran three years ago. It’s a bit better, but still one of the biggest issues facing the OSMF. Working groups need more people. A growing number of members have been attending board meetings, but I’d like to see multiple ones at every meeting. We need good people on the board, but we also need an active membership who are interested in what we do, watch us, what we do, track that we deliver, and offer appreciation in return.

My Experience Worked in Kriminologi.id As SEO & DM

Posted by Aztour on 25 November 2017 in English (English)

As my first experience worked in Kriminologi.id who adressed at Fatmawati Street, Golden Jaya Plaza No. J-34, South Jakarta is very amazing, i can learn how to life with my self without helping of my parents and know more about SEO. In my job As SEO & DM, i think this job just optimizing rank and visitor in search engine, but it's turn out wrong, As SEO & DM I must develop around the SEO like analysist log file for indexing purpose, analysist and bring the improve for sitemap, link building for increase website authority, and many more who can't i list one by one.

Kriminologi.id

Live in Jakarta is my dream, in Jakarta we can see the life of worker who growth fast than other city, i can learn how the attitude in my job with my new co-worker who has funny attitude. But in Kriminologi.id i hope can develop my knowledge more about SEO and can bring the bright future for my life and my new company who i worked now.

OSM is taking up huge amounts of memory on my Chromebook. Is this a known issue or is it because of the huge amounts of tiles, features, etc. that defines OSM?

Geoweek 2017 with students from the University of San Carlos [Cebu, PH]

Posted by GOwin on 24 November 2017 in English (English)

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.

#BC2020 Mapathons

Posted by Noznoc on 23 November 2017 in English (English)

North Battleford, SASK, task (You can see the visualization here and this entry can also be seen on my website.)

BC2020

Building Canada 2020 project (BC2020) is a community-led initiative driven by a simple and clear vision: map all buildings in Canada on OpenStreetMap (OSM) by the year 2020. While interning at Mapbox, the Community Team supported my participation in the BC2020, but but my involvement actually initiated from my work at Statistics Canada on the Crowdsourcing project, as well as my personal interests in volunteered geographic information. For more details about the project, check out the Mapbox "Points of Interest" blog post I wrote.

Though conceptually simple, mapping all buildings in all of Canada on OSM is no simple task. Without a large and diverse group of individuals that are willing to maintain participation, we may find that contirbutions decline with time, as has been seen in many past crowdsourcing projects. Interest usually starts strong, which has been the case so far in BC2020, but other priorities can affect a volunteer's ability to remain committed to a proect, and thus participation can weaken or even stop. Therefore, in my opinion, the success of BC2020 comes from continuous engagement and education to various private and public organizations across all of Canada, which includes NGOs, government entities at various geographic levels, local citizens and experienced OSM contributors, and academic institutions.

Mapathon Organization

There has been a growing interest to incorporate OSM into academia, which I have witnessed online and which my former and current colleagues have informed me they witnessed at the HOT Summit in Ottawa (Sept. 14-15, 2017). With this in mind, Mapbox's Community Team and I believed engaging with Canadian post-secondary institutions would be a great opprotunity to educate academics and students, as well as other interested individuals, about OSM and how to contribute data onto OSM for BC2020 during OSMGeoWeek (Nov. 12-18, 2017) in a meaningful way!

When beginning, I wanted to ensure that the leaders for each mapathon had a GIS background, so I decided to reach out to individuals at various universities and colleges across Canada that were affiliated with either Geothink or were the heads of Geography libraries. After solidifying interest from 8 different groups (2 in BC, 1 in ATLA, 1 in MAN, 3 in ON, 1 in QC), I created a wiki page documenting guidelines and resources for hosting mapathons specifically for mapping buildings on OSM. I also helped identify the area of interest (AOI) that each mapathon would armchair map. Since I wanted to avoid beginner mappers adding buildings within already mapped regions on OSM, I scanned rural Canadian regions on OSM that I suspected would be unmapped. After identifying a suitable region, I then researched whether or not that region had an already existing open dataset of buildings that could be imported. If there was no existing dataset, I concluded that the region was appropriate for the mapathon. Some universities even reached out to their AOI's municipality to see if there were building footprint open datasets that could be imported instead (in which case they would have selected a different region as importing requires more expertise). The municipalities who stated they did not also expressed support for the initiative! It was warming to see eager mapathon leaders connecting with local municipalities, and even local OSM contributors, to collaborate.

Once the AOIs were picked, I wanted to develop tasks in the Canadian Tasking Manager for the mapathons so that the participants had clear instructions on how to map buildings on OSM with the iD editor. (Note: JOSM would have been preferred because the building_tools plug-in makes adding buildings seamless, but there is a learning curve because JOSM's graphical interface is not user-friendly.) After communicating with a Canadian OSM community member about my intentions, I was granted admin rights to create projects in the Tasking Manager. The image below shows a task I created for North Battleford, SASK.

North Battleford, SASK, task

Data Visualization

After the mapathons took place between Nov. 10 - 17, I wanted to analyze and visualize the contributed data. First, I used Overpass Turbo to see what buildings were contributed in the 8 AOIs that were mapped; so, on Nov. 20, I zoomed into each AOI and used the following query to select the OSM buildings contributed from the mapathons: building=yes and newer:7day. I then opened each query within JOSM and saved them as individual OSM XMLs to ensure I didn't lose the metadata, which would have been the case if I directly saved the queries as GeoJSONs from Overpass Turbo. Next, I used osmtogeojson to convert the OSM XMLs to GeoJSONs for each AOI. I then imported the GeoJSONs into QGIS to assess the data. Some GeoJSONs had point and polygon data, but I only imported the polygon data into QGIS. In QGIS, I calculated the total number of contributors and buildings for each AOI. After analyzing the data, I merged all GeoJSONs together using geojson.io. I saved the merged GeoJSON and then used tippecanoe to convert the GeoJSON into a vector tileset. Lastly, I imported the tileset into Mapbox Studio to create a custom style (although I used Mapbox's Standard style as the starting point).

With all the data cleaned, I was ready to create the data visualization. I used Mapbox's Malaria Mapping visualization as a guide, but instead of running the repo's scripts, I just altered the timestamps in Sublime Text (e.g., 2017-11-17T21:26:38+00:00 to 20171117). After adjusting the timestamps, I used Mapbox GL JS to create the time slider functionality. I also wanted every mapathon participant to see their contributions, so I added a button for each participating organization. This way a mapathon leader or participant can be directed to their AOI and review their contributions and stats. From my interactions with the visualization, it was neat to see how some AOIs had mapping done over multiple days.

Validation

I believe validation is very important for BC2020, and more generally to OSM. It is not just about adding data, but about having data that is reliable. Also, validation is especially important because most mapathon participants were beginner armchair mappers and new to OSM. I wanted to make sure the visualization supports validation efforts, thus I added popups so users could select a building footprint and then be directed to that specific building in the iD editor. Also, whenever a user zooms into a selected AOI, they can click on a button to be directed to the task in the Canadian Tasking Manager, or directed to review the validation documentation I wrote up in the wiki. You can see the visualization here!

Conclusion

My work isn't done yet; it is just beginning. I am working with the universities to conduct validation and I intend on adapting the visualization to handle dynamic data that visualizations all changesets with #bc2020 in the comments. Please let me know if you are intersted in contributing or helping in any capacity! As mentioned above, the success of BC2020 requires a group of active participants!

#MY INTEREST IN MAPPING

Posted by jonisia93 on 23 November 2017 in English (English)

I became involved in mapping in 2015 when i joined with my fellow youth mapper in HOT. We Mapped some wards in Dar es salaam like Vingunguti , Mwananyamara, Hanannasif and Mzimuni ward on which we mapped some featured like Drainage features, roads, building features also those areas which are vulnerable for floods . Tools which where used were like GPS, JOSM software, Also there were involvement of community members in order to create awareness in the community about mapping. It was very interesting exercise .

Announcing my candidacy for OSMF Board Elections 2017

Posted by David Dean on 22 November 2017 in English (English)

I have been an active OpenStreetMapper since 2007 (and an OSMF member since early 2016), and have been organising Mapping Parties in my local city of Brisbane, Australia since 2008 (although both activities were a bit quiet for a few years in the middle there - sorry about that!). I want to join the OSMF Board to primarily help increase representation from the AU/NZ/South Pacific Region, and indigenous populations worldwide, and secondarily to bring my decades of expertise in machine-learning to the upcoming challenges of integrating automated mapping with the local-community focus that should always drive OSM contributions.

Since coming back into OSM solidly in the last 5 months, I have re-caught the mapping bug big time. I have mapped locally, and across the world for the Humanitarian OpenStreetMap Team, every single day since July! I am working on re-ramping up my involvement in the project significantly, and I am performing outreach in the local spatial community to increase the awareness of both OSM and the Humanitarian OpenStreetMap Team. I particular enjoy teaching and introducing new members to the project, and have run two Missing Maps events, alongside other local Mapping Parties, and I will continue to organise events locally every month.

I am an active participant of HOT mapping efforts, and I believe strongly in the ability of remote mapping to provide a great starting point for local communities to take ownership of their maps. In fact, I believe that this is the first and foremost principle of OpenStreetMap, that if anything is taking away, or discouraging, local ownership of the map it is probably not a good idea.

If elected, I would seek to improve the representation of the needs of Australia, New Zealand and the South Pacific mappers towards the OSMF Board. In particular, I am very interested, and already working towards, how the OpenStreetMap project and communities can extend our community, models and techniques towards indigenous populations around the world. Indigenous populations often look at the world differently than the Euro-centric origins of the OpenStreetMap project, but I believe that some of the valuable lessons already learnt by HOT in how local disadvantaged communities can take ownership of their maps can be extended and improved upon for the indigenous populations of Australia, New Zealand, the South Pacific, and around the world. To be clear, I am not indigenous myself, but I am in already in the process of building relationships to work towards this goal in the Greater Brisbane area, then hopefully across the entire region, and the world!

One other aspect that I would like to bring to the board will be the present and future impact of automation, machine-learning and/or artificial intelligence on OpenStreetMapping, both generally and specifically for Humanitarian Mapping. It might appear that this is antithetical to my belief in local communities owning local maps, but that is why I want to focus on using these powerful techniques in ways that promote, rather than degrade, local ownership.

I have more than a decade of machine-learning experience, and I want to investigate existing techniques in development by Facebook, Development Seed and others, and develop new ones, and I am working with a team at the University of Queensland to begin a study on how these and similar techniques can be opened to all mappers through the Humanitarian OpenStreetMap Tasking Manager and editing tools in a way that ensures that remote and local mappers are assisted directly in our mapping tools, rather than having the output of an algorithm imported widescale without their direct involvement in the process. I am in particular interested in efforts that can focus on getting ML to people on the ground in things like FieldPapers, and in apps like StreetComplete, Kort and OpenMapKit. We need many more of these great simple-survey focussed approaches, and I think ML can help with guiding these efforts.

You can find out more about me at https://dbdean.com, and my OSM profile at https://www.openstreetmap.org/user/David%20Dean contains links to my many OSM-related activities. If you have any questions, or want to get in contact, please don’t hesitate to ask me here, by email at ddean@ieee.org, or at the Election to Board Talk Page at https://wiki.openstreetmap.org/wiki/Talk:Foundation/AGM17/Election_to_Board, where I will begin to wade through the many existing questions shortly.

Thanks, and Happy Mapping!

Youth Mapping the Driver to Change

Posted by chomba chishala on 21 November 2017 in English (English)

Hello, my name is Chomba Chishala, I am a student doing Environmental Education at the University of Zambia. At the same time the president of the YouthMappers at the University of Zambia Chapter (YMUNZA) I came to know YouthMappers through Open Street Map Zambia (OSMZAMBIA) in February this year 2017 when OSMZAMBIA had a meeting in Lusaka’s Bongo Hive training center. From that meeting, I learnt how to use different tools when mapping including the importance of the maps and how maps can be used for humanitarian help.

As YouthMappers UNZA, we have been involved in different tasks or activities and some of the prominent tasks that we have been doing include the malaria elimination where we have been mapping buildings / houses to help people who are into spraying for malaria as well as distribution of mosquito net as well as mapping for urban and rural areas in Zambia.

Many communities especially in African countries remain underdeveloped due to geographical impediments such as Hills, Mountains and lack of information with regard to how they are distributed especially their location that act as a hindrance to people willing to help in case of an outbreak of a disease.
Thus mapping buildings, roads, and streams as well as showing their actual location and potentials has derived me to engage myself in mapping as many communities as possible for the betterment of most of the communities. ‘’I am a proud YouthMapper who is willing to make a change, just urging everyone out there to join us and make a difference.’’

“As YouthMappers UNZA, our vision is to cultivate a generation of young people to become leaders in creating resilient communities and empowering them to define their world by mapping it.”

On 3rd July 2017 i joined the youth mappers chapter at IRDP and elected as a vice president of the chapter. The introduction of this chapter to our collage has made me realize how important it is to do mapping for risk areas and allocating various social service thus becoming easier for aid provision and security as well as other communal services. GIS and mapping are my core interests therefore joining this chapter will bring me great experience and influence to these two media.

#2017 Mapping

Posted by Wava Stella on 21 November 2017 in English (English)

As a volunteer through Youth Mapping, I have engaged and experienced a lot of interesting projects, mapathons, workshops and training. Started with a HOT Project for mapping for malaria elimination in Zimbabwe Southern Province and Zambia. Ignoring the inconsistency in my diligence, I still manged to deliver awesome and come up as one the good mappers on the project with an appreciation from HOT. A lot of projects followed for which my contribution was mainly remote inclusive the project for response to refugee crisis in Northern Uganda through a number of mapathons, use of some tasks to train on the other members interested in the realm of mapping. Many more project tasks including #Hurricane Irma, #Kasese Floods and a lot not mentioned. And now we have embarked on the #Saving Mothers giving birth in Kyenjojo, Uganda. However, with all these projects and training conducted, JOSM has emerged my best platform for savoring the mapping moment.
