You can move the selection area in the "Display" pane by placing the inside the selection area and dragging.

Once you have the area selected, right-click anywhere in the "Display" pane and select Create New Analysis Area from the shortcut menu.

Selecting Cancel from the shortcut menu will stop the entire new analysis area process and remove the selection area from the "Display" pane.

Now your project window shows the new analysis area in the "Display" pane with the Active grid theme icon Fuel Model theme as the active grid. In the "Tree" pane the new analysis area is identified with the Active Analysis Area icon New Analysis Area item. Since there is now more than one analysis area in the FlamMap project the active analysis area item is identified with the icon. Under this Active Analysis Area icon New Analysis Area item there is a complete set of landscape grid themes and an empty Runs item. Any Runs or output grids from the parent analysis area are not included in the new analysis area.

You can rename this Active Analysis Area icon New Analysis Area item to something more descriptive by clicking twice and editing right in the "Tree" pane.

Export a New Analysis Area

An exported analysis area can be used outside of FlamMap or used to create a new FlamMap project with smaller Project (.PRJ) and Archive (.FZA) Files.

Analysis area shortcut menu with Create Landscape selected.

To save a new analysis area as a separate GeoTIFF (.TIF) or Landscape (.LCP) File right-click the  Active Analysis Area icon New Analysis Area item and select Create Landscape from the shortcut menu. A "Select Destination File" dialog opens where you define the file name and destination folder.

You must choose either the GeoTIFF (.TIF) or Landscape (.LCP) File from the Save as type: drop-down menu.

The GeoTIFF (.TIF) has several benefits,

  • the file size is significantly smaller,
  • there is only one file as projection information is embedded with the data,
  • and the GeoTIFF (.TIF) format is widely supported in GIS, image processing, and authoring applications.
