1 Create georeferenced image of your map
Maptiler, supports many formats, including TIFF/GeoTIFF, MrSID, ECW, JPEG2000, Erdas HFA, NOAA BSB, and JPEG. Most GIS programs will have the option to export your raster data in at least one of these formats.
2 Created tiled map with Maptiler
Select “Google Maps compatible (Spherical Mercator)”. This is the projection expected by Mobile Atlas Creator. Next you need to select the spatial reference system of your input layer. The output is a set of folders, which contain the map tiles, and a doc.kml file.
