Welcome to our Great Salt Lake Wetland Vegetation mapping tool!

We recommend you use Microsoft Internet Explorer or Opera for viewing this imagery.

This website is intended to serve as a tool for Great Salt Lake wetland managers (and interested citizens!), to allow them to calculate how much Phragmites and other wetland vegetation is found on their property.

You will notice four boxes at the top right of the map. Here’s a rundown of what each option does.

Calculate Veg Covers: You can zoom into an area of interest (using scaling bar on upper left of map), then click on “Calculate Veg Covers”, and then click once on the map to start drawing a polygon around the area of interest. For each click, you will create a new vertex of your polygon. When you are done drawing your polygon, “double click”. The program will then automatically generate a graph that shows you the coverage of the different vegetation classes in the area of interest. CAUTION: If you select an area too large or too small, you will bog down and possibly crash the system. We recommend selecting an area larger than 1 acre, but no larger than 10,000 acres for using this calculate veg covers function.

Basemap: This option allows you to change the type of basemap for your imagery. The default basemap is aerial imagery. To change the basemap, click on the “Basemap” icon and select either the “imagery”, “topography”, or “street” option.

Map Info: When you click on the “Map Info” icon, you will see a box that has some general information about the imagery acquired.

Veg Description: When you click once on “Veg Description”, a box pops up that includes an image and a verbal description of each of the nine classifications.

You will also notice a Legend on the far right of the website. This legend tells you the colors that correspond to the different vegetation classes, and allows you to turn on and off different wetland boundaries and different wetland vegetation classes. For instance, you could turn off all vegetation classes except the Phragmites one, to look at the extent of just Phragmites in Great Salt Lake wetlands.
