[OSM-talk] railway lines, tracklogs and the like

[Andy Robinson]

I was heading to Gloucester (by car) this weekend so thought I would map a
bit of the city while I was there. So I looked at what OSM had already (very
little) and then went to the online applet and added the river Severn and
the railway lines from the underlying Satellite imagery. Not great accuracy
of course but good enough for the long radii's you generally find on the
railways and the larger rivers like the Severn. There will still be a bit of
horizontal shift due to the Landsat accuracy but we can live with that for
the rural sections. While I was there I also created the Gloucester and
Sharpness canal from start to finish.

For Mapchester, I used scans of the out of copyright 6-inch to one mile OS
to add the railways, canals & rivers running through the city centre. This
task I accomplished using GPSUtility which can take a 2, 3 or 4 point
rectified image.

Cheers,

Andy
