1.Introduction
2.How MapShed Works
Like AVGWLF, MapShed is a customized GIS interface that is used to create input data for an enhanced version of the GWLF watershed model originally developed at Cornell University. In utilizing this interface, the user is prompted to identify required GIS files and to provide other information related to “non-spatial” model parameters. This information is subsequently used to derive values for required model input parameters which are then written to the input file needed for model execution. Also accessed through the interface is regional climate data stored in Excel-formatted files that is used to create the necessary “weather” input file for a given watershed simulation.
With MapShed, a user selects areas of interest, creates model input files, runs the simulations model, and views the output in a series of seamless steps.
3.Walkthrough
The following screen shots demonstrate how to use MapShed. You can also view MapShed video tutorials in a later section in this document (https://wikiwatershed.org/help/model-help/mapshed/#video-tutorials).
4.Software Downloads
*Note: Some download links point to files on Google Drive. If your firewall prevents access to Google Drive, please email webmaster@stroudcenter.org for assistance.
MapWindow Application
MapWindow is the primary software required in order to run MapShed. Note: since MapShed is a plugin designed to work within MapWindow, you must install MapWindow prior to installing MapShed. Only the version provided on this site will work with MapShed.

GWLF-E Application
This is the standalone GWLF-E application. Note: This application is included with the MapShed download. Only download this application if you are NOT using the MapShed software. This application is a simple executable that can be run immediately after downloading it. There is no installer.

Important: If you are receiving Microsoft related errors while attempting to run this executable, you are missing required Microsoft components. These components are included with the MapShed installation package. If you wish to only run the standalone executable, you must install both MapWindow and MapShed and then uninstall MapShed and then MapWindow. The required Microsoft components will remain installed.
Maintenance Downloads
