FAQ
GEN to JP2 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 JP2 files?
JP2 or JPEG 2000 is an improved version of JPEG, one of the most popular file formats for storing and transferring images. Compared to the latter, JP2 image files offer higher quality and smaller size images by using a different compression algorithm, which can be either lossy or lossless. JP2s are created using the JPEG2000 Core Coding application, but can also be obtained through conversion from other formats.
