Parameter descriptions

Input1: Input raster channel or layer

Specifies the input raster channel or layer to use in generating the report. The raster can be of any data type.

Bitmap: Input bitmap

If specified, the report is generated only for pixels under the bitmap.

Units

Specifies the area units to use in the report.

The default value is Hectares.

Report

Specifies where to direct the generated report.

Available options are:

• LOG: generates a report on the terminal (default)
• <modulename.RPT>: appends a report to the module's RPT file
• DISK: generates a report on file "IMPRPT.LST"

Details

The report generated from AREAREPORT enumerates every pixel in the raster along with its description (from metadata), the percentage of the total area covered by the pixel, the cumulative percentage, the total number of pixels, and the area in units specified by the user. If no metadata entry is available for the description, the name is listed from any existing in the metadata.

Optionally, the report can be generated for only the pixel values that fall under a specified bitmap.

Pixels with a NO_DATA_VALUE are omitted from the report.
