FAQ
GML to CG4 Conversion
What are GML files?
GML (Geography Markup Language) is an XML-based language for describing geographic features, developed by the Open Geospatial Consortium (OGC) and adopted as the international standard ISO 19136. A GML file is readable text in which every object on a map, such as a building, a road, a lake, or a boundary, is written down together with its shape and its attributes, for example a name, a type, or a population. The language is a toolbox rather than a fixed list of objects: communities and organizations define their own application schemas on top of it, which is how national mapping data, cadastral records, and the data of 3D city models are exchanged. GML is also the standard way for web map services to return features.
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.
