Make Raster Layer (Data Management)

Summary

Creates a raster layer from an input raster dataset or layer file. The layer 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

• The output can be created with only a subset of the bands. This will save time and disk space.

• You can use a raster layer from a GeoPackage as the input. To reference a raster within a GeoPackage, type the name of the path, followed by the name of the GeoPackage and the name of the raster. For example, c:\data\sample.gpkg\raster_tile would be your input raster, where sample.gpkg is the name of the GeoPackage and raster_tile is the raster dataset within the package.

Parameters

Dialog

Label	Explanation	Data Type
Input raster	The path and name of the input raster dataset. You can use a raster layer from a GeoPackage as the input. To reference a raster within a GeoPackage, type the name of the path, followed by the name of the GeoPackage and the name of the raster. For example, c:\data\sample.gpkg\raster_tile would be your input raster, where sample.gpkg is the name of the GeoPackage and raster_tile is the raster dataset within the package.	Composite Geodataset
Output raster layer name	The name of the layer to create.	Raster Layer
Where clause (Optional)	Define a query using SQL or use the Query Builder to build a query.	SQL Expression
Envelope (Optional)	The output extent can be specified by defining the four coordinates or by using the extent of an existing layer. Default—The extent will be based on the maximum extent of all participating inputs. This is the default. Current Display Extent—The extent is equal to the data frame or visible display. The option is not available when there is no active map. As Specified Below—The extent will be based on the minimum and maximum extent values specified. Browse—The extent will be based on an existing dataset.	Extent
Bands (Optional)	The bands that will be exported for the layer. If no bands are specified, all the bands will be used in the output.	Value Table

Python

arcpy.management.MakeRasterLayer(in_raster, out_rasterlayer, {where_clause}, {envelope}, {band_index})

Name	Explanation	Data Type
in_raster	The path and name of the input raster dataset. You can use a raster layer from a GeoPackage as the input. To reference a raster within a GeoPackage, type the name of the path, followed by the name of the GeoPackage and the name of the raster. For example, c:\data\sample.gpkg\raster_tile would be your input raster, where sample.gpkg is the name of the GeoPackage and raster_tile is the raster dataset within the package.	Composite Geodataset
out_rasterlayer	The name of the layer to create.	Raster Layer
where_clause (Optional)	Define a query using SQL.	SQL Expression
envelope (Optional)	The output extent can be specified by defining the four coordinates or by using the extent of an existing layer. MAXOF—The maximum extent of all inputs will be used. MINOF—The minimum area common to all inputs will be used. DISPLAY—The extent is equal to the visible display. Layer name—The extent of the specified layer will be used. Extent object—The extent of the specified object will be used. Space delimited string of coordinates—The extent of the specified string will be used. Coordinates are expressed in the order of x-min, y-min, x-max, y-max.	Extent
band_index [band_index,...] (Optional)	The bands that will be exported for the layer. If no bands are specified, all the bands will be used in the output.	Value Table
