Erosion Distance (`Burn') Data

A `burn' data file is comprised of a header, fiducial polygon coordinates, and the burn number data. The binary header is comprised of the following:

• nx (integer) horizontal dimension of data set
• ny (integer) vertical dimension of data set
• polys(integer) number of fiducial polygons

The fiducial polygon coordinates follow next and are stored in binary format. The burn data is stored as a one dimensional sequence of binary signed characters. Each slice is stored in a separate file.
