As the name implies, a Tarsier Raster Data file (.tra) is Tarsier's gridded data format. It is made up of two parts: 1) an ASCII header file that specifies the structure of the grid and data properties, and 2) a series of data values stored in binary.

A typical Tarsier header looks like:

Cols 25 Rows 25 XLLCorner 0 YLLCorner 0 CellWidth 1 CellHeight 1 NoDataValue -9999.000000 Projection 0 Precision float Format binary
