1. Installation Procedures

The Land Analysis System (LAS) consists of three software packages. They are:

TAE - Transportable Applications Executive
TAE interacts with end-users and manages the execution of the LAS applications. See the TAE Programmer's Reference Manual (not delivered) for detailed information on TAE.

LAS - Land Analysis System
LAS is image analysis routines designed to ingest, manipulate, and analyze digital image data and provide the user with a wide spectrum of functions and statistical tools for image analysis. See the LAS Overview for detailed information about LAS.

ADAPS - AVHRR Data Acquisition and Processing System
The AVHRR Data Acquisition and Processing System (ADAPS) is designed to receive, archive, and process Advanced Very High Resolution Radiometer (AVHRR) data from National Oceanic Atmospheric Administration (NOAA) Tiros-N polar orbiting satellites. See the ADAPS Overview for detailed information about ADAPS.

This section describes the procedure needed to install the LAS package. Please read all of the information within the System Managers Guide before beginning.

LAS 7.3 has been installed on computer systems that support the following configurations. See Appendix B if you have an unsupported machine.

Previous versions of LAS have also been installed on the following systems:

Disclaimer

Although this software has been successfully installed on a computer system of the Geological Survey, U.S. Department of the Interior, no warranty, expressed or implied, is made by the Geological Survey as to the functionality of the software on any other system, nor shall the fact of distribution constitute any such warranty, and no responsibility is assumed by the Geological Survey in connection herewith.

1.1 Install Instructions

LAS 7.3 consists of three compressed Unix tar files. To restore the executables, approximately 180 megabytes of disk space is required. To optionally install from the source code, approximately 150 megabytes additional disk space is required.

Installing from the LAS tar files :

  1. Create a top level directory
  2. Change to the top level directory
  3. Uncompress and extract the TAE tar file
  4. Uncompress and extract the executable tar file
Example:

     % mkdir -p /your_path_name/las73  
     % cd /your_path_name/las73 
     % zcat /tar_file_dir/tae.tar.Z | tar xvpf - 
     % zcat /tar_file_dir/las73_run.tar.Z | tar xvpf - 
Note:

1.2 Environment Variable Assignments

The environment variables TAE and EDCSOFT need to be set to define access to LAS 7.3.

     % setenv EDCSOFT /your_path_name/las73 (Root directory for LAS 7.3)
     % setenv TAE $EDCSOFT/tae  (Root directory for the TAE package)
After the root environment variables have been set, the user can set up the other required environment variables for LAS 7.3 by executing the commands:

     % set response=las71
     % source $EDCSOFT/env/las/assign/lasinit

If development by a programmer is required, the environment variables for access to the libraries and include files can be set up by executing the commands:

     % set response=las71d
     % source $EDCSOFT/env/las/assign/lasinit

Environment variables to LAS 7.3 will be setup when lasinit has been executed. Usually, the previously stated commands are placed in a masterlog file and the user's .login file.

At this point LAS 7.3 is installed. The user can type las at the operating system prompt to enter the LAS environment. To exit LAS, the user can enter exit to return to the operating system. See the LAS Overview for detailed information about getting started.

Example:

     % (Operating system prompt)
     % las (Enter the LAS environment)
     LAS73> (LAS environment prompt) 
     LAS73>exit (Exit the LAS environment)
     % (Back to the operating system prompt)

1.3 Installation Notes

 
       % mkdir -p /your_path_name/las73
       % cd /your_path_name/las73
       % zcat /tar_file_dir/tae.tar.Z | tar xvpf -
       % zcat /tar_file_dir/las73_src.tar.z | tar xvpf - 
       % setenv EDCSOFT /your_path_name/las71
       % setenv TAE $EDCSOFT/tae 
       % cd $TAE
       % installtae  |& tee build.log
       % cd $EDCSOFT
       % cp $EDCSOFT/src/las/env/install/mkdir.csh .
       % mkdir.csh
       % cd $EDCSOFT/src
       % cp $EDCSOFT/src/las/env/install/Build.las .
       % Build.las |& tee build.log
