Build Overviews (Data Management)

ArcGIS Pro 3.4 | | Help archive

Summary

Defines and generates overviews on a mosaic dataset.

Usage

  • This tool will honor the default mosaic dataset settings, not the properties set on a mosaic dataset layer. For instance, the tool will not accept layer property changes such as band count, mosaic method, extent, or query—these properties will be determined by the mosaic dataset and default properties of the mosaic dataset.

  • You must check on Define missing overview tiles, Generate overviews, or both.

  • The first overview level is created on the full resolution of the mosaic dataset. Each subsequent level is built on the last overview level that was generated.

  • If you need more control over the definition of the overviews, use the Define Overviews tool first.

  • By default, the overviews generated for mosaic datasets in a file geodatabase are stored in a folder <gdbname>.Overviews in the same location where the geodatabase containing the mosaic dataset exists. The overviews generated for mosaic datasets on the enterprise geodatabase are stored within the geodatabase containing the mosaic dataset. These locations can be changed by first using the Define Overviews tool and specifying a location.

  • You cannot build overviews for a referenced mosaic dataset.

Parameters

LabelExplanationData Type
Mosaic Dataset

The mosaic dataset where you want to build overviews.

Mosaic Layer
Query Definition
(Optional)

An SQL statement to select specific rasters within the mosaic dataset. The selected rasters will have their overview built.

SQL Expression
Define Missing Overview Tiles
(Optional)

Identify where overviews are needed and define them.

  • Checked—Automatically identify where overviews are needed and define them. This is the default.
  • Unchecked—Do not define new overviews.
Boolean
Generate Overviews
(Optional)

Generate all overviews that need to be created or re-created. This includes missing overviews and stale overviews.

  • Checked—Generate all overviews, including those that already exist. This is the default.
  • Unchecked—Generate only the overviews that have been defined but not yet generated.
Boolean
Generate Missing Overview Images Only
(Optional)

Use if overviews have been defined but not generated.

  • Checked—Overviews that have been defined but not generated will be generated. This is the default.
  • Unchecked—Overviews that have been defined but not generated will not be generated.
Boolean
Regenerate Stale Overview Images Only
(Optional)

Overviews become stale when you change the underlying raster datasets or modify their properties.

  • Checked—Identify and regenerate stale overviews. This is the default.
  • Unchecked—Do not regenerate stale overviews.
Boolean
