Tool download, installation, & dependencies

The Delta Landscapes Scenario Planning Tool (DLSPT) is an ArcPy Toolbox designed for ArcGIS 10.x and Python 2.7.5 with ArcPy (installed with ArcGIS). It does not currently work with ArcGIS Pro / Python 3.x – a ported version for ArcGIS Pro is in development. Python libraries used are either packaged by default with Python or pre-installed with ArcGIS/ArcPy (e.g. NumPy). 

The DLPST is designed to work out-of-the-box and no specific installation process is required aside from downloading and unzipping the tool contents.  To obtain a copy of the Delta Landscape Scenario Planning Tool please submit your name and email address using the form on this page. You will receive an email with a link to download the zipped product.  The zipped folder containing the tool should be unzipped in the user’s preferred directory, and then navigated to within ArcMap or ArcCatalog. See the “Tool Workflow” section of the User's Guide for additional instructions. Your contact information will be stored and used solely for communicating critical information about tool updates, new versions, and bug fixes. We will not share your information with any other organization or service.

Because of the analyses performed, an advanced license of ArcGIS is required to run the tool. Certain modules (fish support, inundation, and subsidence) also require the Spatial Analyst extension.
