I finally finished the Cairo sketching I started back in January. By "finished" I mean I've worked around the entire edge of the city, creating landuse=residential areas to dilineate the extents.

It's now reasonably clear how big the city is, although it turns out its quite a strange shape. Some areas particularly in the East near the airport, have lots of new upmarket construction projects happening (or did when they took the aerial photos)

I suppose I should fill in the grey patches in the middle. But that's even more tedious. Also in the middle there's probably areas which are not technically residential.

Maybe I'll look for another "armchair mapping" project to keep me occupied whilst half watching TV.
