Having both GoPro Hero11 and Max360, I was curious whether there would be any use from running both cameras at the same time. While Max 360 captures all around, would Hero 11 possibly have better resolution, which could be useful for streetview platforms like Mapillary and Panoramax, thus also providing additional detail for OSM mapping?

Here’s the same object - a surveillance camera - from both action cameras. Hero11 is even a little bit further away.

As can be seen, Hero11 does offer notably better resolution, which could be crucial with signs and other objects - thus it does make sense to collect imagery with two cameras like that at the same time.

My first diary entry in thirteen years, and so much has changed on OSM. The editing tools have come on so much, and there is now an incredible level of detail, even in the rural town I’m living in now. I think I need to go back to the documentation to refresh my memory and look at adding all the things missing in my neighbourhood.

On April 3, 2024, an earthquake happened outside the coast of Hualien, which caused serious roadblocks and human casualties. OpenStreetMap Taiwan has opened 3 projects for mapping affected areas, requesting worldwide mappers to map buildings, landuses, missing roads or waterways in Hualien.

We are talking if there is a possibility to donate the newest satellite image after the earthquake to map the after-earthquake situations. And the possibility of hosting mapping events on-site after the affected area returns to normal, helping locals by mapping the newest map data.

That’s the name of the workshops I facilitated last week, with the goal of introducing/promoting OpenStreetMap, along with introducing tools like FieldPaper, OpenAerialMap, Sketch-Map Tool and Umap, to meet the objectives of local DRR practitioners’ upcoming mapping initiative.

Last Friday I had conducted two workshop in Iloilo, one (unplanned) for Iloilo’s Provincial DRRMO (disaster agency), and another for Iloilo City own DRRMO. In the Philippines, city charters may provide them autonomy from the geographic province they’re part of. These Disaster Risk Reduction Management Offices (a tongue-full, I know) are the government agencies responsible for mitigating localized disaster risks, and planning for disaster prevention for their respective territories.

Last year, in a random visit in Iloilo, I met some folks from the City DRRMO team and since then, I found out that they’ve capturing community-based hazard risks and perceptions using FieldPapers. Unfortunately, FieldPapers uptime wasn’t as reliable as before, and eventually the built-in Bing imagery became unavailable, too.

I’ve kept in touch with the City’s DRRMO team, and when I told them of a planned (gustatory) visit, they asked if I could run another training workshop for them. The small workshop was planned for a dozen people, but the day before the workshop I was surprised to learn than they confirmed 28 participants, and couldn’t even accommodate my own guests.

Well, that’s how I ended up with two separate workshops, discussing the same topic, but interestingly, the engagement was different with one group being more technical, and familiar with geodata/GIS/maps, and the other are more focused on being able to collect local spatial knowledge.

Anyway, with the feedback about issues they’ve been encountering with FieldPapers, I ran into the updated Sketch-Map Tool which now has built-in ESRI Aerial Imagery included.

FieldPapers (FP)

One of the earliest Pen & Paper tools I’ve learned to like, especially when working with folks averse to “tech”. It’s cheap, and it (used to be quite) reliable.

Creating maps could be tedious, manually requiring people to manually define their area of interest. I think it’s been years since the search function last worked properly.

The participant’s favorite feature is FP’s ability to use external TMS endpoints, and in our case, I demonstrated how OpenAerialMap imagery taken from drones can be used to deploy fresh maps that can be used as background of maps they wish to deploy on the ground.

They participants also like how FP serves TMS tiles of the uploaded snapshot (marked-up) map, which they can use as a background layer on iD (or another editor) for digitizing on OpenStreetMap.

Maximum paper size is ISO A3, which isn’t probably big enough when you expect participants to work together as large groups. That size is more than sufficient for individual mappers though.

If the users aren’t conscious about it, they may inadvertently create atlases with snapshots that may reveal personal or private information, so that’s one thing users should really watch out for.

Sketch-Map Tool (SMT)

This recently revamped tool now comes with built-in satellite imagery from ESRI, but you’re limited to that or the Mapnik (OpenStreetMap’s default layer) background for your maps.

The interface for creating maps is more friendly, and the OHSOME map quality report helpful, but it becomes tedious when you need to create separate maps for a large area, which one has to to create one-by-one.

image

One of the favorite features for SMT is it’s built-in ability to digitize (properly) marked features and create GeoTIFF and GeoJSON files out of the marked-up map. The data is not stored in HEIGIT’s servers, so the risk of accidental disclosure of private information is minimized.

During the role-playing segment, we experienced how quick the process may be like, from map creation, to the mark-up/reporting process, and the automatic digitization, then visualizing the created GeoJSON files quickly, using Umap.

Over-all, everyone found the tools easy-enough to learn, and accessible for their capacity level.


At it is, these two tools are complementary and one could be more useful than the other, depending on the users’ priorities. To wit:

  FieldPapers Sketch-Map Tool
supported layer Mapnik, HOTOSM, TMS Mapnik, ESRI Imagery
interface functional, but search doesn’t work more user-friendly, works as expected
registration optional none
max. paper size ISO A3 ISO A1
geodata GeoTIFF GeoTIFF, GeoJSON
TMS of marked-up map yes no
multi-map support yes tedious
privacy risks moderate low

I’m excited by the initiatives being drawn-up by both DRRMOs, though they are still working independent of each other.

The search and rescue team, and the local fire department, were very enthusiastic about using Pen & Paper to help map location of water wells (parts of the city are experiencing drought), while the search and rescue intends to use them for mapping highways attributes (width and access) and missing footways and paths, to improve response times during emergencies.

I see a potential to make more use of OpenStreetMap data in their local communities, encouraging local contributors to keep the map updated and relevant for their own needs, and the participatory approach they are undertaking, in collecting local spatial knowledge and experience, which could lead to improved usability of gained results for local capacity assessments, and the role of the OSM ecosystem of data and tools serving as a bridge into their formal DRR process.

I would’ve loved to see more of the local active mappers participating in the event and planned activities, but unfortunately, we failed to receive any word from the folks we reached out to.

Below is a collage of some photos from the activity.

While commercial map providers like Google, provide map data in local Indian languages, the local language labels are usually transliterated from English, resulting in errors. OSM, Wikidata and Wikipedia platforms provide a way to improve the local language maps leveraging multilingual labels through Wikidata identifiers on OSM, through semi automated updates. For good quality maps on Wikipedia and OSM, the Wikidata location needs to be accurate and Wikidata identifier should be uniquely mapped to the actual OSM geometry. I worked on removing the mismatches for villages of a district in Andhra Pradesh. I have documented my experience as clearly as possible, so that even users with less programming and tools skills can contribute to the work. As an example, identifying and fixing errors in Wikidata location is given below.

Identifying and fixing error in locations on Wikidata pages

Error in Wikidata location, as the place name is not seen on the background OSM map, before the error is fixed The geodata is presented in Wikidata page and corresponding English Wikipedia article page using OSM as background map. If one notices that the marker is not near to the names identified on OSM map, then there is possibility of an error. Even if the name is identified on OSM background map, selecting different zoom levels allows checking whether the place is in the correct location.

Obtaining the correct geo location for Gurazala, Palnadu district, Andhra Pradesh using Bharatmaps The correct geolocation is obtained from Open Data compliant StateGIS portal run by Bharatmaps.

Wikipedia page with corrected Wikidata location shown on OSM map for Gurajala After Wikidata coordinate location is updated with the correct data, Wikidata page and the corresponding English wiki article show the correct map.

Full article covers how to identify more complex errors based on the geographical distance between Wikidata location and OSM node location and also when the Wikidata and OSM geometry that is associated are outside the area of interest. Sample Wikidata Sparql scripts leveraging Sophox interface to OSM, which can be easily edited are provided to help contributors with less programming and tool skills to contribute to these efforts.
