FAQ
FGB to CG4 Conversion
What are FGB files?
FGB is the extension of FlatGeobuf, a modern binary format for geographic vector data, created by Björn Harrtell and published as open source. A file holds a collection of features, which are points, lines, and polygons with their attributes such as names and codes, together with the coordinate system and the extent of the data. The format is built for speed: an optional spatial index, built in a smart way, lets a program pick out only the features in a chosen area without reading the whole file, and the same trick works over the internet, where just the needed bytes are downloaded. Files are written once and then read many times, which suits large collections of static data, and the format has no size limit of the kind that older formats like Shapefile have.
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.
