FAQ
GDB to CG4 Conversion
What are GDB files?
GDB here is the Esri file geodatabase, the standard native storage of ArcGIS for geographic data. It is not a single file but a folder whose name ends in .gdb, and inside it the program keeps many data sets together: feature classes with points, lines, and polygons, tables of attributes, rasters, and the rules and relations that connect them, such as topology, networks, and subtypes. Esri introduced it in 2006 as a faster successor of the personal geodatabase and a more capable replacement of the Shapefile, and it is now the usual way to store and share GIS projects from ArcGIS. A single table may grow to a terabyte, and the geodatabase itself has no size limit. Because the data are kept as a folder, it is usually sent in a ZIP archive.
What are CG4 files?
CG4 is a raster format associated with CALS (Continuous Acquisition and Life-Cycle Support) — a program initiated by the US Department of Defense to capture and link military data. CG4 is compatible with a very limited number of digital graphics programs. Files with this extension contain a bitmap that often uses the CCITT4 compression, which is an old fax machine standard used for black-and-white images.
