What is Maplorer?
MAPLORER is a free ‘moving map’ navigation program for Windows CE and Windows Mobile based portable devices such as GPS systems, PDAs and smartphones.
You can use MAPLORER with maps captured as JPG images. It organizes the maps in tiles, allows you to navigate through them and add Pois (points of interest). Map coordinates can be added using a POS text file. MAPLORER can then display your current position, load and log tracks, etc.achieve even better performance.
The program seems to be no longer updated. Last version, 2.10, released in June 2012, can be still downloaded from the official website.
