Generate Blind Spot Areas (Intelligence)

Summary

Creates an output nonvisible area, or blind spot, for input Intelligence, Surveillance, Reconnaissance (ISR) or patrol visible buffer features based on start and end times. The output blind spot layer is used with the time slider to visualize and explore areas that are not visible to ISR or patrol assets at specified times.

Usage

• You can use the Generate Coverage Areas tool to create an input layer for this tool.

• The Output Features parameter will have the following output fields:

  • Start Time—Date time value when the asset turns on or begins coverage
  • End Time—Date time value when the asset turns off or ends coverage.
  • Percent Visible—Percentage of the Clip Features parameter value that is covered by the asset
  • Percent Blind—Percentage of the Clip Features parameter value that is not covered by the asset, also known as the blind spot

• The Output Features parameter will also create a corresponding .lyrx file containing symbology and time properties for use in the time slider.
