Make Raster Layer (Data Management)

Summary

Creates a raster layer from an input raster dataset or layer file. The layer that is created by the tool is temporary and will not persist after the session ends unless the layer is saved to disk or the map document is saved.

This tool can be used to make a temporary layer, so you can work with a specified subset of bands within a raster dataset.

Usage

• To make your layer permanent, right-click the layer in the table of contents and click Save As Layer File, or use the Save To Layer File tool.

Syntax

MakeRasterLayer_management (in_raster, out_rasterlayer, {where_clause}, {envelope}, {band_index})

Parameter	Explanation	Data Type
in_raster	The path and name of the input raster dataset.	Composite Geodataset
out_rasterlayer	The name of the temporary output raster dataset.	Raster Layer
where_clause (Optional)	A query statement using the fields and values of the raster dataset. To add this variable, press F8, or right-click and click Insert Variable.	SQL Expression
envelope (Optional)	Using the min x, min y, max x, or max y, you can specify the extents of the raster layer. To add this variable, press F8, or right-click and click Insert Variable.	Extent
band_index ID (Optional)	Choose which bands to export for the layer. If no bands are specified, then all the bands will be used in the output.	Value Table
