Libyan Rebels Advancing Into OSM Territory

Posted by AndrewBuck on 10 July 2011 in English (English)

Libya has been designated as a HOT project area for a while now due to the on-going hostilities there. There is hi-resolution imagery on Bing for the Tripoli area which is already pretty well mapped, however there is also imagery for the cities of Al Khums and Zlitan which has a lot of un-mapped area in it.

The conflict has been at a stalemate for a while, however just in the last few days the rebels have begun to advance again. The BBC reports that the rebels have started pushing westward from Misrata toward Zlitan, and they are also advancing northward from Gharian toward this same area.

Whether the rebels are able to use OSM in their activities or not, we know that various aid organizations do monitor it for coordinating their efforts. It would be nice if we had the area completely mapped as best we can from the existing imagery by the time these aid organizations move into the area.

Here are the stories from the BBC referenced above, as well as the bounding box of the hi-res imagery for the area so you can see where to work. Tomorrow I will try to put together another diary post detailing specific things that I think would be useful to map, as well as techniques for spotting them in the imagery.

Zlitan seems to be covered in a usable state, but we should try to coordinate, as there are still some nearly white areas in the map. I thin the map is usable in its curent state in the areas near the coastline and in the city of Zlitan. The area west of Zlitan needs further work, Google says, that there is a village called Al Jum'ah 10 kilometers southwest of Zlitan. We don't cover this village and most of the outskirts of Zlitan between the City Center and Al Jum'ah.

I think it would be a good idea to mention this issue on the mailing list.

If you want to make a mailing list post you are welcome too, I don't follow mailing lists much so I haven't done much with them. I see you have been doing a lot between Al Khums and Zlitan which was really empty, looks much better now.

I plan to keep alternating between doing buildings east of Zlitan and continuing the "rural" road network in the far southeast corner. This way I am working in a different area so we avoid edit conflicts and/or duplication of objects.

If you are working in rural areas, there is a collection of GPS tracks donated to us which may be helpful.

I have used the GPS tracks in the past and they are quite useful for the area they cover however they are almost all in the southwest portion of the country. Also, because it was a recreational driver many of the tracks are just driving around in circles out in the sand dunes and not necessarily on roads. They have been useful though and if you find out about any others let me know.
