Raster Compare (Data Management)
Release 9.2 Last modified November 29, 2010	Print all topics in : "Tools"

Related Topics

Compares the properties of two rasters datasets or two raster catalogs and returns the comparison result.

Usage tips

The tool returns messages showing the comparison result.
The following environments affect this tool:current workspace, scratch workspace.

Command line syntax
An overview of the Command Line window
RasterCompare_management <in_base_raster> <in_test_raster> <Raster Dataset | GDB Raster Dataset | GDB Raster Catalog> {ignore_option;ignore_option...} {NO_CONTINUE_COMPARE | CONTINUE_COMPARE} {out_compare_file}

Parameter	Explanation	Data Type
<in_base_raster>	The raster dataset that will be compared to the test raster.	Raster Layer \| Raster Catalog Layer
<in_test_raster>	The raster dataset that will be compared to the input base raster.	Raster Layer \| Raster Catalog Layer
<Raster Dataset \| GDB Raster Dataset \| GDB Raster Catalog>	The type of comparison. Raster Dataset — Compares raster dataset properties. GDB Raster Dataset — Compares properties of rasters datasets in a geodatabase. GDB Raster Catalog — Compares properties of raster catalogs in a geodatabase.	String
{ignore_option;ignore_option...}	The properties specified will not be compared during comparison.	String
{NO_CONTINUE_COMPARE \| CONTINUE_COMPARE}	Indicates whether to compare all properties after encountering the first mismatch. NO_CONTINUE_COMPARE — Stop after encountering the first mismatch. This is the default. CONTINUE_COMPARE — Compare other properties after encountering the first mismatch.	Boolean
{out_compare_file}	The name and path of the text file which will contain the comparison results.	Text File
