Wetland Map of Nevada

Project Description

Wetland Map of Nevada 

As part of a grant from the United States Environmental Protection Agency, the Desert Research Institute has compiled existing geospatial and remote sensing data for Nevada into a statewide map of wetlands. This map incorporates data from multiple sources, including:

• USFWS National Wetlands Inventory
• USGS National Hydrography Dataset
• NRCS GSSURGO soils data
• Spring locations from the Spring Stewardship Institute
• The DRI Map of Riparian Vegetation for Nevada
• Wet meadow maps from USFS and the University of Nevada, and
• Landsat normalized difference vegetation index data

This map product indicates which sources contributed to the identification of a mapped wetland polygon and provides a confidence indicator based on the number and type of coincident sources.

Wetland Analysis Toolbar

The WetBar application is an ArcMap toolbar (Desktop version only) that links in real-time to Google Earth Engine in order to calculate time-series of climate data, vegetation vigor and waterbody extent from Landsat imagery from 1985 to current, access and past aerial photography, and other geospatial data. Definition of study areas is like a simple paint program and requires no knowledge of ArcMap editing methods. The toolbar application organizes information on wetland study areas, allowing the user to group and sort sites based on various criteria. The toolbar can generate a wide variety of information for a selected site, such as descriptions of the extent and hydrological setting, soils, climate, land ownership, wetland type, phenology, interannual variability in vegetation and hydrology, and more. 

Version 1.1c of the WetBar installation (1.1 GB) can be downloaded at the right of this page.  The Wetbar manual is in the top level of the unzipped directory tree. If you already have downloaded the full installation, you may download just the WetBar toolbar and double-click it to install.  Users must successfully register Earth Engine with Google (free for research use).
