OpenStreetMap Bangladesh Community (OSMBD) have been trying to fill up the missing parts of Dhaka city on OpenStreetMap as a part of long term disaster risk reduction & resilience initiative collaborating with different government & non-government organizations for a while. However, as we all know Dhaka is a constantly growing Megacity and this makes tough to have it completely mapped at a time.

This time we are initiating “Map Your City” project to map the complete road network of Dhaka city to the block level including landmarks. We will also have Mapillary street level photos taken as a part of the mapping. . It will make sure the proper navigation & routing possible for Dhaka using OpenStreetMap, which will be very helpful for NGOs, Governments and donors.

Please trace buildings (building=yes) and map roads and smaller paths for as far as you can follow them. It is important to:

  • Trace the building using the outline of the roof and then shift the feature to line up with the ground-level footprint of the building.

  • Some of these squares may already be partially or fully mapped, please review and map missing features if needed, fix up the existing mapping, or just mark it "Done" if already complete.

  • 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.

  • Most buildings are rectangular, after drawing the outline, use the 's' key in the iD web editor to "square" the corners. In case of using JOSM use 'Q' key to square.

  • 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.

  • Use Bing imagery for mapping. If you use other imagery, mention it in the comment.

  • In the comment, write what you actually mapped, for example: "mapped buildings"

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).

While mapping "Roads" please consult http://wiki.openstreetmap.org/wiki/WikiProject_Bangladesh#Roads for details and examples of mapping roads in broader OSM Wiki for mapping and tagging guidance.
