Creating a Landscape Mask

Landscape Masks are polygons that analysts use to change fuel characteristics in a defined area on the modeled landscape. Analysts use these masks to make modeled fire more representative of observed fire behavior, or to incorporate more recent changes that are not represented in the existing fuel layer (fire activity, beetle kill, blow-down, etc.).

You can create a landscape mask on either the Analysis or Situation Map. To create a landscape mask, you can:

• Draw a Landscape Mask using the rectangle or polygon drawing tools on either the Analysis or Situation Map (see instructions below),
• Copy a fire perimeter or analysis ignition shape and save it as a Landscape Mask,
• Select, copy and save a historical fire shape as a Landscape Mask, or
• Upload them just like any other shapefile. (See also the Uploading Shapes video.)

To draw a landscape mask:

1. Navigate to the appropriate map by doing one of the following:
   • Choose Incidents tab > select the Incident > click Assess Situation.
   • Choose Analyses tab > select the analysis > click View Information > Analysis Map. (The Analysis Landscape file must already exist before you can do this option.)
2. Pan and zoom into the area where you wish to draw a mask.
3. Select the map tool you want to use to create a shape on the map (rectangle or polygon).
4. Place your cursor on the map and draw the shape.
5. Click the green plus  icon to the right of the Landscape Masks layer.
6. Enter a Name for the mask.
7. Click Save. The temporary shape appears both on the map with the given label and in the Layer Tree under Landscape Masks

NOTE: The Situation Map and the Analysis Map have the same functionality. The View Landscape Map currently only views the landscape.
