Hey, folks. After finding some issues with the MadMappers Somalia
roads dataset, which were hard to fix automatically, like occasional
doubled roads, I finally concluded that the best thing for us to do is
to merge the roads data into the OSM database manually:


The dataset covers all of Somalia, and is pretty detailed. Each of the
128 files comprises a rectangular geographic region of varying sizes,
with ~1,050 ways in each file. I cleaned up the data to minimize
topological errors, and converted it to OSM format, with a basic
tagging scheme. However, the data does still contain issues in some
places, such as the occasional set of doubled/overlapping roads. Also,
these files still need to be merged in with the data that's already in

We need volunteers who have experience with JOSM! Please help out by
visiting the link above and spending some time merging and uploading
the new Somalia roads data.

It's going to be a bit of work, but if we spread it around, it won't
be too bad, I hope -- and it will be totally worth it. The roads data
here is incredibly detailed, and will undoubtedly be very useful for
humanitarian aid.
