The Wildlife Conservation Society (WCS), an NGO focused on protecting species worldwide, and the International Peace Information Service (IPIS), an NGO delivering data and analysis on peace topics, sustainable development and the fulfillment of human rights.
This project aims to map road, residential areas and if possible artisanal mining activities in the park. There are many stresses in the national parks of DRC, including deforestation, illegal hunting (poaching) and armed-actor controlled artisanal mining.
Both organisations are dedicated to work to reduce these tensions and work towards durable peace. WCS does this with the focus on safe and well organised park service, bringing stability tho the animals and people living in the park. IPIS has a lot of experience with mapping artisanal mining sites, and diffusing such information to inform actors in the peace process.

- #hotosm-project-2843 #IPIS #WCS Traced based on 2010-2013 Bing imagery. When saving your work, please leave the default comment but add what you actually mapped, for example "added buildings and a residential road".
In case you wouldn't be familiar with some of the objects described below, you will find additional tips and pictures here.
- Some places in the park are (illegally) used as for small scale ('artisanal') mining. Mining areas can occur in the middle of the forest or along riverbanks, and can be recognised as 10 to 100 meters wide areas with exposed earth, often with visible structures such as pits or machinery.
- Support camps may be spotted nearby and should be tagged as buildings.
- Mining areas should be entered as polygons and tagged with 'landuse=quarry' in JOSM, or as 'Quarry' in the iD editor. You can use the search box in iD to find it the first time.
Deforestation due to Logging
- Some cases of deforestation due to logging will be visible via satellite imagery. If you see such an area, please discuss with someone during the mapathon event before tagging it: Just raise your hand excitedly: "I have a question! Does this look like logging?" :)
- Tagging logging in iD is a little tricky since it's not very common. The simplest is by first tagging an area with some kind of land use (e.g. residential), and then changing the tag from 'landuse = residential' to 'landuse = logging'. Logging can be mapped using the 'landuse=logging' tag in JOSM.
- Please draw one large area outline around groups of buildings and tag them landuse=residential
- About 5 or more buildings can be outlined as a landuse=residential area.
- Do your best to keep the outline close to buildings and not include a lot of farmland or forest.
- When to draw the residential area outline takes some judgement, but when in doubt, draw an outline around the settlement.
- leisure=common - Open flat areas of grass or dirt in a settlement, often with paths across them
- leisure=pitch - An identifiable sports field of some sort, usually football/soccer, baseball
- leisure=park - An open area that you personally know to be an official park or recreation area
- landuse=grass - Open, flat grassy area, not a farm field or crops.
Roads and Paths
- Please map roads and major paths as completely as possible by connecting them to the main road networks where ever possible.
- Very short segments that do not connect to anything should not be mapped.
- Short segments of a road or path that you cannot see through the trees but seem very likely to exist should be mapped to keep the road complete
- Try and map a little beyond your task square so the person who maps the task square next to yours can easily connect them.
- Always connect roads to other roads where they meet and never end roads on Residential area polygon edges.
Roads are classified by usage (function), for a good explanation, please see the Highway Tag Africa page in the osm wiki. The below classifications are a summary of Highway Tag Africa and how they are applied using to the two main OSM Editors.
You will most often use the following "Road Features" and "Path Features" (iD Web Editor):
- Minor/Unclassified - This is for roads that connect small villages and settlements
- Residential Road - These are roads that are in settlements but only are used for access to houses and buildings.
- Unmaintained Track Road - This is for roads that only lead to farm fields or forests. They do not connect settlements or residential areas.
- Path - This is for small paths that are usually used by people on foot or 2 wheeled vehicles. They may or may not connect settlements or lead to farm fields. Only map the major paths that connect to settlements or other roads.
In JOSM you apply the same classifications, just with a different user interface where the above classifications are displayed this way in JOSM:
- highway=unclassified - This is for roads that a vehicle with 4 wheels could travel on that connect small villages and settlements
- highway=residential - These are roads that are in settlements that only are used for access to houses and buildings.
- highway=track - This is for roads that a 4 wheel vehicle or farm tractor could travel on and only lead to farm fields or forests. They do not connect settlements.
- highway=path - This is for small paths that a 4 wheeled vehicle could not travel on and are usually used by people on foot or 2 wheeled vehicles. They may or may not connect settlements or lead to farm fields. Only map the major paths that connect to settlements or other roads.
- Please accurately outline all the buildings you can find. The outline should be for the full size of the building even if it is partly covered by trees in the imagery.
- After drawing the outline, use the 's' key in the iD web editor to "square" the corners.
- Many buildings are very close, but do not actually touch each other, try to map them close to each other without letting them connect or share nodes with each other, roads or residential area outlines. In the iD web editor, holding down the "alt" key will keep nodes of "snapping" to each other and accidentally connecting.
- In the iD web editor, the first time you map a building you will use the "Building Features" category and then at the top of the list select "Building" again, this is the most generic building tag we can use as we almost never can tell the more specific use of any building from imagery alone.
Only if you have personal knowledge of a building, please add that information to the building, like the name or type of building (hospital, school, gas station, etc)
