Dataset Utility Software
Several programs have been written to faciitate working with some of the
datasets in the ESSC database. The function and usage of each module is
documented in the module header. Currently available are
- Perl subroutine to open Arc/Info INFO tables and create
templates for unpacking records.
- C-language source and MSDOS execuable versions of a standalone
program to print the contents of an LAS (Land Analysis System)
data descriptor record file, which includes dataset size and
- C-language source and MSDOS executable versions of a standalone
program to read digital elevation model (DEM) files in either
the traditiional USGS ASCII format or the new SDTS
(Spatial Data Transfer Standard) format, create a binary array
of 16-bit elevation values, and print the header information.
- C-language and Fortran versions of a function to extract
subarrays from binary data files in band sequential (BSQ)
format. This is the output format from the read_dem program and
is also the default format for LAS image data files.
