			map name		(string)
			map dir			(string)

	Parameters
			Name		Type		Def	Min	Max
			----		----		---	---	---
			filename	(string)	NULL	--	--

INPUTS
(none)

OUTPUTS

map name	the full path name of the ASCII map description file

map dir		the name of the directory of the ARCinfo gen map file sources 

PARAMETERS

filename	the full path name of the MAP LIST

list		the description choices for selecting a map

go		send the output when button is pressed

autogo		send the output if any input or parameter changes

DESCRIPTION

This module reads from the MAP LIST the top 
map directory  (map dir).  Additionally, for each entry in the MAP LIST,
a description is read and displayed as a user choice for selection.  Beside
each description is a list that specifies the map directory where the map
description file can be found as well as the specific map description file
itself. When a description is selected from the list, the module
creates full path name for the map description file and outputs it along with 
the top map directory name.  These parameters are passed to the "GET MODEL MAP"
module.

-------------------------------------------------------------------------
The MCNC Environmental Programs Group has created this module as part of a
suite of AVS demo modules, networks, and sample data sets to demonstrate 
the functionality of its visualization prototype for an Environmental 
Decision Support System (EDSS).  This system provides a unified method of 
analysis and visualization for data output from different environmental air 
quality models.  Remotely, standard output files from the following models 
can be read into AVS:

        ROM (Regional Oxidant Model)
        RADM (Regional Acid Deposition Model), low res and high res
        RADM (Regional Acid Depostion Model) Emissions, low res
        UAM (Urban Airshed Model, regulatory version)
        UAM (Urban Airshed Model, AREAL research version)
        UAM Wind (Urban Airshed Model, regulatory version)
        MCNC ALPHA-Prototype netCDF files

Alternatively, xdr portable binary AVS fields can be created from these
data types and accessed directly from the local workstation.

You can download these modules individually from the IAC using anonymous
ftp to the appropriate directories /avs_modules at avs.ncsc.org.  
If you would like to download the entire suite of modules, networks, and
sample datasets at the same time, the IAC recommends that you use 
anonymous ftp to grab the following file from avs.ncsc.org -

/sample_data/avs_data/MCNC_Env_Pgms/MCNC_Env_Pgms.tar.Z

This contains all source code to all local and remote modules, as well as
all of the sample datasets, networks, documentation, installation, and
usage notes.
