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.

  • 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.

String
Query Definition
(Optional)

An SQL expression to select raster datasets that will be included in the output mosaic dataset.

SQL Expression
Extent from 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. If a dataset is selected in Extent from Dataset, those coordinates will automatically appear here.

Envelope
Using Input Geometry for Selection
(Optional)

Limit the extent to the shape or envelope when a feature class is selected in the Extent from Dataset parameter.

  • Checked—Select based on the shape of the feature. This is the default.
  • Unchecked—Select based on the extent of the feature class.
Boolean
Scale Field
(Optional)
Legacy:

This parameter has been deprecated and is ignored in tool execution. It remains for backward compatibility reasons.

Field
Minimum Cell Size 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
Maximum Cell Size 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
Maximum Visible Cell Size
(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.

  • Checked—Generate the boundary. This is the default.
  • Unchecked—Do not generate the boundary.
