Hi,
In the map download tool I have fixed the yellow already-downloaded preview rectangles to correctly show their coverage regardless of map_ or top_ projection.
But the green box is still dumb. To get it correct, the code needs to know if it is a top_ or map_ which will be downloaded. For landsat at least this changes with selected scale.
I think the solution is to add a field to mapsource_struct in map_download.c to hold PROJ_TYPE_MAP or PROJ_TYPE_TOP etc ints. The type would be defined in the scale levels and so would be available for the green box code.. an alternative for Landsat is to use the unused zoom field for that, but I think a more general solution would be better.
currently you have to wait to see what you have got until after the download is complete. (and there is no "delete highlighted tile from map_koords.txt option if it is no good [I don't think I'd use that if there were, but..])

e.g. it's wrong when the preview shows a map_ box but the tile to download will be a top_.
