Create Referenced Mosaic Dataset (Data Management)

Summary

Creates a separate mosaic dataset from items in an existing mosaic dataset.

Usage

• A referenced mosaic dataset can be created in a geodatabase or a folder. When the mosaic dataset is created in a folder, it will not include a boundary.

• Overviews cannot be created for a referenced mosaic dataset.

• You can use this tool to create a mosaic dataset from another mosaic dataset when you want to create a mosaic dataset with a different output. For example, you can create one mosaic dataset with elevation data and create another that will be used to produce a derived product, such as slope or hillshade.

Syntax

CreateReferencedMosaicDataset(in_dataset, out_mosaic_dataset, {coordinate_system}, {number_of_bands}, {pixel_type}, {where_clause}, {in_template_dataset}, {extent}, {select_using_features}, {lod_field}, {minPS_field}, {maxPS_field}, {pixelSize}, {build_boundary})

Parameter	Explanation	Data Type
in_dataset	The mosaic dataset from which items will be selected.	Mosaic Layer; Mosaic Dataset
out_mosaic_dataset	The referenced mosaic dataset to be created.	Mosaic Dataset
coordinate_system (Optional)	The projection for the output mosaic dataset.	Coordinate System
number_of_bands (Optional)	The number of bands that the referenced mosaic dataset will have.	Long
pixel_type (Optional)	The bit depth, or radiometric resolution, of the mosaic dataset. If this is not defined, it will be taken from the first raster dataset. 1_BIT —A 1-bit unsigned integer. The values can be 0 or 1. 2_BIT —A 2-bit unsigned integer. The values supported can be from 0 to 3. 4_BIT —A 4-bit unsigned integer. The values supported can be from 0 to 15. 8_BIT_UNSIGNED —An unsigned 8-bit data type. The values supported can be from 0 to 255. 8_BIT_SIGNED —A signed 8-bit data type. The values supported can be from -128 to 127. 16_BIT_UNSIGNED —A 16-bit unsigned data type. The values can range from 0 to 65,535. 16_BIT_SIGNED —A 16-bit signed data type. The values can range from -32,768 to 32,767. 32_BIT_UNSIGNED —A 32-bit unsigned data type. The values can range from 0 to 4,294,967,295. 32_BIT_SIGNED —A 32-bit signed data type. The values can range from -2,147,483,648 to 2,147,483,647. 32_BIT_FLOAT —A 32-bit data type supporting decimals. 64_BIT —A 64-bit data type supporting decimals.	String
where_clause (Optional)	An SQL expression to select raster datasets that will be included in the output mosaic dataset.	SQL Expression
in_template_dataset (Optional)	Select raster datasets based on the extent of another image or feature class. Raster datasets that lay along the defined extent will be included in the mosaic dataset. To manually input the minimum and maximum coordinates for the extent, use the Extent parameter.	Feature Layer; Raster Layer
extent (Optional)	The minimum and maximum coordinates for the extent.	Envelope
select_using_features (Optional)	Limit the extent to the shape or envelope when a feature class is specified in the in_template_dataset parameter. SELECT_USING_FEATURES —Select using the shape of the feature. This is the default. NO_SELECT_USING_FEATURES —Select using the extent of the data in the feature class.	Boolean
lod_field (Optional)	Legacy: This parameter has been deprecated and is ignored in tool execution. It remains for backward compatibility reasons.	Field
minPS_field (Optional)	Specify a field from the footprint attribute table that defines the minimum cell size for displaying the mosaic dataset; otherwise, only a footprint will be displayed.	Field
maxPS_field (Optional)	Specify a field from the footprint attribute table that defines the maximum cell size for displaying the mosaic dataset; otherwise, only a footprint will be displayed.	Field
pixelSize (Optional)	Set a maximum cell size to display the mosaic instead of specifying a field. If you zoom out beyond this cell size, only the footprint will be displayed.	Double
build_boundary (Optional)	Rebuild the boundary. If the selection covers a smaller area than the source mosaic dataset, this is recommended. This is only available if the mosaic dataset is created in a geodatabase. BUILD_BOUNDARY —The boundary will be generated or updated. This is the default. NO_BOUNDARY — The boundary will not be generated.	Boolean
