Map of Niger

Mapping Niger is still in very early stages. Almost no gps- tracks exist for this region.


Things that are done

Cities
  • The capital Niamey is mapped almost to street level detail
  • almost all of the 50 biggest cities are on the map, not to street level detail
  • about 12000 towns and villages are imported from the Geonames Name Server
Roads

Goals

If you have a goal that you are working towards or one that you would like to see get done (and are maybe willing to get the ball rolling) then add it to the list here, create a section where it can be coordinated and tracked, and a way of measuring progress. And then get on with it :-)

URGENT ǃ dec 13th 2014 Niger's government ask for help in order to host nigerian refugees crossing the southern border. Needs for mapping concerns water wells, schools, residential areas, tracks, intermittent rivers, farmland First to map is the Diffa region (SE of Niger)

  • water wells - 13th dec'14 we have 1986 wells in Niger. Look at the wells that are present(e.g. in Maradi) and carry on. It might help UN.
  • schools - If you can please locate schools. It will help UN.
  • Niamey - Map the capital city
  • Maradi région and espacially the south of it. (because it is small and has a good satellite coverage)
  • Tertiary highways imported from vmap0 have to be checked against Bing imagery. Some turned out to be simple tracks barely visible.
  • Secondary highways can be improved with Bing.
  • Track imported from vmpa0 Don't seem to have enough precision to be kept.
  • Airport positions imported from ourairports.com can be improved/confirmed.

We didn't find the exact location of following airports ; Téra, Birni N'Konni, Maine-Soroa , Bilma

  • Village names imported from GeoNet Name Server can be confirmed by surrounding their area as residential landuse.

A lot of mapping can be done, even if the whole country is not yet covered.

  • I found several public domain maps in wikipedia:

there are some lowres maps for the outlines of national parks of Niger floating around somewhere in wikipedia

Tools

  • Geonames Name Server:

Thousands of villages were imported from this database. Location is sometimes as far as 2 to 3 Km away from the actual town situation. If the place seems to be in the middle of nowhere do following tag as

place = hamlet

fixme = Please Locate

If placement correction is obvious then move the POI to the good location.

Progress

So far I did a lot of tracing of the Yahoo imagery. Niamey is coming together nicely, even some (2!) other mappers started to join me. The tracing of inter city roads is progressing as well. The accuracy is certainly poor and not quite up to the usual openstreetmap standards, but since we are lacking gps data one has to live with that for the moment. Tracing of overland highways can only be done by the low resolution imagery.
