Forest inventory viewer help

Forest Inventory Viewer mapping application

The Forest Inventory Viewer mapping application displays information on state-administered lands. The Forest Inventory Viewer interactive maps are based on DNR core GIS (Geographic Information System) data holdings. This help document explains the tools and search methods to view forest inventory information on state-administered lands.

Overview

Initially when you open Forest Inventory Viewer, the viewer is always zoomed out to the statewide extent. Notice that the only features that is visible on the map at the statewide extent is Background Layers—Forest Inventory Index. This layer shows where the Forestry Inventory data exists in beige-color. You will use this layer as a guide where you can zoom in to view the Forestry Inventory data.

As you zoom in further, layer names become darker and features on the map are visible. You will eventually see features on the map, and layer names in the TOC are no longer grayed out.

If you want more detailed information, you can switch to one of the layers: Hardwood Forest Types, Conifer Forest Types, Size Class, or Age Class.  Click on Refresh button if the map doesn’t refresh or background layers look weird.  Notice you can only view one layer under Forest Inventory layer category.
