iMap for Mac

From SweetCocoa:

iMap is a powerful, yet easy-to-use program designed for mapping large amounts of latitude / longitude data. iMap works with different kinds of picture maps (TIFF, JPEG, PICT, GIF or PNG), ensuring appealing and information-rich maps.

The program is supplied with a plethora of ready-to-use maps. Additional maps can be downloaded from the Internet, exported from GIS software or they can be scanned. The calibration of the maps can be done from within iMap. iMap can plot symbols or characters from any font installed on your system, enabling to map an unlimited number of different taxa. Additionally, it offers the possibility to create a QuickTime movie from a sequence of maps in order to trace the vegetation history of a certain area.

Distribution maps can be printed at high resolution or they can be exported for incorporation in presentations, web pages, posters, reports, movies or publications. Distribution maps can be exported as BMP, PICT, Photoshop, JPEG, PNG, SGI, TGA, TIFF and QuickTime image files.
