Creating an Analysis Ignition File

A Fire Behavior Specialist can create (draw rather than copy a shape or upload a shape) an Analysis Ignition file for use in a STFB, NTFB, or FSPro fire behavior analysis. The ignition file can be a point, line, or polygon and the analyst can create it from the Analysis Map or the Situation Assessment Map.

Note: Be careful not to draw the ignition shape too close to a barrier. If the ignition overlaps the barrier shape, you could get unexpected results from your analysis.

To create an analysis ignition:

1. Choose Analysis > select analysis you want to add an ignition file for > View Information > Analysis Map.
2. To select the map layers you want to view and to see the map legend, click the Map tab > mark/unmark the appropriate checkboxes for the map layers you want to view. (Clicking the + sign next to the layer name expands the tree view.)
3. Select the map tool you want to use to create the ignition file (point, line, or polygon).
4. Place your cursor on the map where you want to start drawing, then click once.
5. Move the mouse to the end point, then double-click to release the tool. The shape turns yellow and has a temporary name.
6. Verify that you have not created your ignition shape on unburnable fuels.

   To do this, select the identify icon and click within the ignition shape. The information about that point on the landscape appears on the Info tab in the left pane.

7. Click the + to expand the Analysis layer.
8. Click the icon to the right of Ignitions.
9. Enter a Name for the shape. Be sure to use descriptive names (e.g., Ignition 5/25/10).
10. Click Save. The temporary shape name changes to the one that you entered and appears in the tree view with a checkbox next to it.

When you go to the Analysis Parameters page for this analysis, the ignition file you created appears in the Ignition file drop-down list.
