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
