Hello everyone,

Further to my message last night I can now load Landsat data into my GPX 
editor. There's a demo, of the Southampton Water area, available here:

There must be, however, some sort of projection issue. The coastal path is 
slightly in the water! The tracks were surveyed with a Garmin GPS while the 
Landsat data is from the NASA server, so at a guess, the Garmin is programmed 
to use the UK projection while the NASA server the standard worldwide 
projection?

BTW on the subject of an editor, I can see a use for two variants with two 
slightly different user bases:

- a heavier-weight client-server app for live OpenStreetMap editing, based on 
Steve's applet (I have done some work on this this week)
- a lightweight app specialised for GPX editing and integration of Landsat 
data for estimation of woods and lakes (my C++ app, from which the screenshot 
is taken).
