This directory contains programs intended to facilitate working with
some of the datasets in the ESSC database.  The function and usage of
each module is documented in the module header.

    openinfo.pl		Perl subroutine to open Arc/Info INFO files and
			create templates for unpacking records.

			NOTE:  This subroutine was modified 1998 Oct 27
			to fix an error -- if one item name was a subset
			of another (e.g., "name" and "fullname"), the
			shorter name was erroneously interpreted as
			matching the longer name.

    printddr.c		Program to print the contents of an LAS (Land
			Analysis System) data descriptor record file,
			which includes dataset size and georeferencing
			information.
    printddr.exe	Executable for MSDOS.

    read_dem.c		Program to read digital elevation model (DEM)
			files in either the traditional USGS ASCII
			format or the new SDTS (Spatial Data Transfer
			Standard) format, create a binary array of
			16-bit integer elevation values, and print the
			contents of the type A and type C header records
			(for the ASCII format) or the equivalent
			information from the SDTS documentation records.

			NOTE:  This program was modified 2001 Dec 27 to
			add support for an alternate interpretation of
			the SDTS standard used for some SDTS DEMs.

    read_dem.exe	Executable for MSDOS.

    readbsq.c,		Subroutine to extract subarrays from binary data
     readbsq.for	files in band sequential (BSQ) format.

    statsgo		Directory containing Perl and AML scripts for
			extracting soil physical and hydraulic
			properties from the STATSGO database.

    las			Source code for LAS version 7.4.
