FAQ
GEN to ICO Conversion
What are GEN files?
GEN is the General Information File of ARC Digitized Raster Graphics (ADRG), a military raster map format defined by the U.S. National Imagery and Mapping Agency, now the National Geospatial-Intelligence Agency (NGA), in the MIL-A-89007 specification. ADRG was designed around 1989 to provide a digitized map or chart background for mission planning, command and control, and cockpit display systems. A dataset consists of several files: the .gen file holds the descriptive information and the names of the image files, while the .img files hold the actual picture, which is a scanned paper map or chart. A transmittal header file with the .thf extension may also be present. The data are georeferenced with the ARC system, which divides the earth into 18 latitudinal zones, and are traditionally distributed on CD-ROM.
What are ICO files?
ICO files contain the images used as icons for files, folders or programs on the Microsoft Windows platform. The icons appear on the desktop, in Windows Explorer or in the Start Menu and help identify each item. ICO images are generally of a small size, are scalable, and they can also serve as website logos or symbols that appear in the web browser next to the URL. The equivalent of ICO files on Mac computers is called ICNS.
