********  LAS Disclaimer  *******

The USGS EROS Data Center (EDC) has provided LAS to outside users
since 1983 and continues to provide limited support.  Originally, the
LAS and ADAPS system was developed to support research and development
of image processing applications within NASA and the USGS and has
migrated to provide special services for EDC image production.  Since
the software is public-domain, it is available to any government or
private institution.

As the popularity of these systems has grown, so has the impact of
external support on EDC resources.  This impact has greatly hampered
the continued development of EDC's internal image processing
capabilities.  As a result, EDC no longer provides external support.
Occasionally, limited support will be considered for agencies with
whom we have cooperative agreements or mutual goals.

NOTE ADDED BY PSU Center for Environmental Informatics:
    EDC appears to have discontimued all LAS development in 2004.  As of
    early 2006, the EDC Web site for requesting LAS, given below, was no
    longer accessible.  Copies of the EDC LAS 7.4 distribution have been
    placed on a local ftp site at PSU, and may be downloaded without any
    formal request.  The URL is ftp://dbftp.essc.psu.edu/pub/code/las. 

All requests for copies of these software packages must be made
formally.  The request should state that you have read and understand
this disclaimer.  Distribution is now made available through the world
wide web, unless otherwise requested.

               *********************************

The following packages are included:

LAS - The Land Analysis System is an image processing, image analysis
and raster GIS system originally developed cooperatively by NASA's
Goddard Space Flight Center (GSFC) and the U.S. Geological Survey's
EROS Data Center (EDC).

ADAPS - The AVHRR Data Acquisition and Processing System is a
reception, processing, and product generation system for AVHRR imagery
from NOAA satellites.  ADAPS was built using the LAS system and
additional capabilities.

XID - The X Image Display program allows users to display and
interactively manipulate images on display terminals running the X
Window System.

TIEPTS - Allows users to interactively select tie points between
unregistered images and a reference source, such as a registered
image, a base map, or vector data.

Documentation is provided in Hyper Text Markup Language (HTML).

LAS/ADAPS are currently available on the following platforms:

              Silicon Graphics:     Built and tested on IRIX 6.5
              Sun:                  Built and tested on Solaris 2.7
