FAQ
GMT to CG4 Conversion
What are GMT files?
GMT is a text format for map vector data used by the Generic Mapping Tools, a widely used open-source collection of programs for drawing scientific maps and graphs, developed by Paul Wessel and Walter Smith. In its simplest form, a file is just a list of coordinates of points or lines, with a line starting with the character > marking the start of each new line. In the newer form, the file also carries a header written in comments, which names the type of shapes, the extent, the coordinate system, and the attributes of each feature, such as a name or a depth, so that points, lines, or polygons with their attributes can be kept in one file without a separate table. This version was introduced to improve exchange with other GIS programs.
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.
