What is c-squares?

Document Actions
C-squares home page at CMAR Australia

C-squares is a system for storage, querying, display, and exchange of "spatial data" locations and extents in a simple, text-based, human- and machine- readable format. It uses numbered (coded) squares on the earth's surface measured in degrees (or fractions of degrees) of latitude and longitude as fundamental units of spatial information, which can then be quoted as single squares (similar to a "global postcode") in which one or more data points are located, or be built up into strings of codes to represent a wide variety of shapes and sizes of spatial data "footprints".

"Spatial data" (short for "geospatial data") in this context means any data which relate to a particular position on the earth's surface - and thus, for example, could be plotted on a map.
