ENVIAgDevelopingHotspotColorSliceTask

ENVIAgDevelopingHotspotColorSliceTask

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.

Syntax


Result = ENVITask('AgDevelopingHotspotColorSlice')

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

Output properties (Get only): OUTPUT_RASTER

Properties marked as "Init" are applied only during the initial creation of the object. Properties marked as "Set" are those that you can set to specific values after the object has been created. You can also retrieve their current values any time. Properties marked as "Get" are those whose values you can retrieve but not set.

Methods


This task inherits the following methods from ENVITask. See the ENVITask topic in ENVI Help.

DESCRIPTION

NAME

REVISION

See the ENVITask topic in ENVI Help for details.

This task also contains the following properties:

INPUT_RASTER (required)

Specify a single-band raster.

OUTPUT_RASTER

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

OUTPUT_RASTER_URI (optional)

Specify a string with the fully qualified filename and path of the output raster. If you do not specify this property, the output raster is only temporary. Once the raster has no remaining references, ENVI deletes the temporary file.

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.
