Landsat and others !

People are marching into my territory . I have to shoo them off LOL

First thing I noticed was rail route which I planned to map later by taking a train from upstream to downstream stations . It came thanks to planemad's clever usage of railway route map .

Next I noticed that the highway junctions on outskirts which I screwed up were looking good . That was done by the katpatuka whom I earlier bugged for drawing a road totally off the place.

Next I learned that LandSat imagery is available and lakes and water bodies started appearing . I had to correct the rectangle looking Lakaram lake to something more accurate :)

LandSat imagery is good . I have to now mark all rivers and canals in my area. Does any one know how to judge a river to be a line or a closed water area ( I mean how much width ?)

Rivers and canals should always be mapped as ways (in the direction of flow); if you want to have an area, then you can add an area with waterway=riverbed around the river itself. The width where it makes sense to add an area depends a bit where the river is: In a densely populated city where people are likely to use high zoom levels it might be reasonable to use an area even on rivers that are 5 meters wide while in a remote wilderness it might be okay to have a 50 m wide river just as a way.
