I have a bunch of topographic maps in the format of .map files and 4000x4000px png files.I would like to view them as a slippy map and be able to select an area and export that as one big image. I am wondering what my options are. QGis would be nice, or Mobile Atlas Creator, which supports local tiles as source for the following formats: OSMTracker, AndNav, BackCountry Navigator, Maverick and OSMAND.

It would be nice if at some time I could convert them to something more standard, like 256px tiles under a coordinate dir structure, or mbtiles so I could view it with tilemill or their server or map on a stick software.

So what are my options to getting these files to open in some slippy map way and being able to export specific areas as images.

I don't care what formats I have to convert to or which software/servers I have to install.

Global Mapper might be able to do that.

The documentation states: "There are also options on the File menu for loading control points and projection information from an OziExplorer .map"

And Global Mapper can definitively export maps or part of maps as 256px tiles (or to other formats).

Global Mapper can load the .map files directly, from there use the "File >> Export web format..." menu to a tile system (there are about 10 choices). – matt wilkie Mar 20 '12 at 19:58

v1.8+ can read (but not write) Ozi Explorer OZF2/OZFX3 raster datasets. Either the image file or the .map file can be passed to GDAL. To retrieve georeferencing specify the .map file.

The gdal2tiles utility can go from source file to slippy map in one step (example commandline for windows):

gdal2tiles z:\data\ z:\data\ ... z:\data\   d:\webmap
start d:\webmap\openlayers.html
