The first file is the header file which contains 80-byte records of American Standard Code for Information Interchange (ASCII) characters that describe the general content of the data set. Files 2 through 5 contain the binary raster data layers. Each raster layer contains 1443 8-bit (one byte) values in each of 1145 lines. Files 6 through 8 contain ASCII files that provide examples of the type of ARC Macro Language (AML) files used to create this data set from the original vector data.
