FAQ
GEN to GLTF 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 GLTF files?
glTF or GL Transmission Format is a vector extension developed by the non-profit consortium Khronos with the aim of improving interoperability between various types of software specialized in creating and accessing 3D content. The extension is compatible with several application programming interfaces (APIs) that offer 2D and 3D vector graphics rendering, including WebGL, OpenGL ES and OpenGL.
