This is a great program, so thanks to all those that have developed it, and I have it working fine in the uk with Virtual earth Hybrid/sts/imagery; also google sts, but can't get google imagery working - one issue.

Another thing I would like to do is load topo maps for walking eg 1:50k and 1:25k. Is it possible to load your own maps with say an ESRI world file:
Line 1: A, pixel size in the x direction in map units (ususally deg long per pixel)
Line 2: D: rotation about y axis (ususally 0)
Line 3: B: rotation about x axis (ususally 0)
Line 4: E: pixel size in the y direction in map units (ususally deg long per pixel)
Line 5: C: x coordinate of the center of the upper left pixel (51.45256)
Line 6: F: y coordinate of the center of the upper left pixel (-1.27247)

or possibly a geoTIFF, which has the geo coding within the tif header?
Hence one could scan, or download a piece of map, coordinate it using either method the load into a separate directory fo use? I can supply examples of both world file with tile and geoTIFF>

The only other way would be to cut up the map into the exact pieces that Maemomapper file directory expect, could be v labour intensive, especially the file creation/naming.

Cheers.
No, this is not possible with Maemo Mapper. And I hate to say it, but it probably will never be supported directly within Maemo Mapper. This is (I think) how GpsDrive works, and that's how Maemo Mapper started out, but it's just too cumbersome to work with on an scale larger than just a few dozens of maps.

It is possible to write a script or program to convert a GpsDrive-style image/metadata into Maemo Mapper's expected file hierarchy, but like you said, it would be a bit of work.

Topographic maps are available in the form of WMS maps. See this page for example URI formats.

Note that you must install "proj" in order to use these maps. You don't however, need the patch mentioned on that website, as it has since been integrated directly in Maemo Mapper since version 1.3.
