Parameter descriptions

InputTHMR: Input raster channel

Specifies the channel of thematic raster data to convert.

Output: Output raster channel

Specifies the output channel to which the converted raster is written. The pixel values for this raster are based on the selected attribute from the input thematic layer. If this parameter is not specified, output is sent to a new channel.

Attribute to write

Specifies the name of the attribute field to use when encoding the new raster layer.

The attribute must be numeric, as these values are written as pixel values in the output raster channel. The attribute name is not case-sensitive.

Use selection

By default (when Use Selection is not checked), the entire thematic raster is converted to the output raster. When Use Selection is checked, then only the areas that are currently selected in Focus will be converted to the output raster.

Details

THMR2RAS converts the thematic raster to a raster by encoding each pixel with a value based on a selected attribute. The attribute must be a numeric data type.

A thematic raster is a raster with associated attributes. Normally, rasters present spatial information as pixel values. Thematic rasters have an associated attribute table that can store more information than just a pixel value. In some cases, you may want to use THMR2RAS to convert a thematic raster to a regular raster. You specify an existing attribute to provide the pixel values to burn into the output raster and the information from the rest of the attributes is not part of the output layer.
