Summary

	Name		TIME SPAN TEXT	
	Type		mapper	
	Inputs		input timestamp		(string)	
			input cropslice		(string)
	Outputs		 textout		(string)
	Parameters	 (none)

Description

The TIME SPAN TEXT module creates a special label for data that involves
multiple time steps (1-N).  The output includes the first and last timestamp
as defined, not only by the input timestamp, but also by the input cropslice
information that contains the range of X, Y, Z, and Time data possibly
cropped and/or sliced upstream.

Inputs

input timestamp		input timestamp string
input cropslice		input cropslice information on crop and slice ranges

Outputs

textout			a label showing the first and last date/time values 
			for the span of time to be represented

Parameters

(none)

-------------------------------------------------------------------------
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.
