OpenStreetMap 開放街圖
The OSM - file for Niger grew over the past couple of days from 353 KB to a whooping 557.6KB. Thanks to all the contributors.

While it doesn't seem not much in the days of dvd and blueray, try to imagine the footprint of a single POI in the OSM database- about 200 Bytes. That's well over a thousand new POIs, waypoints etc. - bziped!!!!
Awesomeness....
Happy mapping,
Christian

Hey you two, thanks for your work! DBusse, respect to you for drawing in all those buildings, that´s some real dedication. (More than I could muster.) Btw, have you looked at the Google satellite imagery for Niamey? The town has really grown since the Yahoo image was taken, it's almost twice as large! Let's hope Yahoo releases more more recent images soon, and increase their high-res coverage a bit.
