This task creates a classification raster based on color slices that represent the difference of Z-scores between two rasters calculated from Getis-Ord Gi* hotspot analysis.

This task requires a separate license for the ENVI Crop Science Module; contact your sales representative for more information.

Syntax


Result = ENVITask('AgDevelopingHotspotColorSlice')

Input parameters (Set, Get): INPUT_RASTER, OUTPUT_RASTER_URI, THRESHOLD

Output parameters (Get only): OUTPUT_RASTER

Parameters marked as "Set" are those that you can set to specific values. You can also retrieve their current values any time. Parameters marked as "Get" are those whose values you can retrieve but not set.

Input Parameters


INPUT_RASTER (required)

Specify a single-band raster.

OUTPUT_RASTER_URI (optional)

Specify a string with the fully qualified filename and path of the associated OUTPUT_RASTER.

  • If you do not specify this parameter, or set it to an exclamation symbol (!), ENVI creates a temporary file.
  • If you set it to the hash symbol (#), ENVI creates a file in the temporary directory, but this file will not be deleted when ENVI closes.

THRESHOLD (optional)

Specify the threshold for the first color slice. The default is 3.0 standard deviations. Lower values reveal more hotspots, while higher values reveal fewer hotspots.

Output Parameters


OUTPUT_RASTER

This is a reference to the output developing hotspot color slice raster of filetype ENVI.
