An overview of the Mosaic Dataset toolset
The following table summarizes the tools in the Mosaic Dataset toolset.
| Tool | Description |
|---|---|
Adds raster datasets to a mosaic dataset from many sources, including a file, folder, table, or web service. | |
Defines which editing operations nonowners have when editing a mosaic dataset in an enterprise geodatabase. | |
Performs checks on a mosaic dataset for errors and possible improvements. | |
Updates the extent of the boundary when adding new raster datasets to a mosaic dataset that extend beyond its previous coverage. | |
Computes the extent of every raster in a mosaic dataset. This tool is used when you have added or removed raster datasets from a mosaic dataset and want to recompute the footprints. | |
Inserts the Cached Raster function as the final step in all function chains within a mosaic dataset. | |
Defines and generates overviews on a mosaic dataset. | |
Generate or update seamlines for your mosaic dataset. Seamlines are used to sort overlapping imagery and produce a smoother-looking mosaic. | |
Computes the visibility levels of raster datasets in a mosaic dataset based on the spatial resolution. | |
Makes transitions from one image to an adjoining image appear seamless. | |
Identifies areas within a mosaic dataset that have changed since a specified point in time. This is used commonly when a mosaic dataset is updated or synchronized, or when derived products, such as cache, need to be updated. This tool will enable you to limit such processes to only the areas that have changed. | |
Create an empty mosaic dataset in a geodatabase. | |
|
Specify items from a mosaic dataset and create a separate mosaic dataset out of those items. | |
Specifies one or more values to be represented as NoData. | |
Lets you set how mosaic dataset overviews are generated. The settings you make with this tool are used by the Build Overviews tool. | |
Deletes a mosaic dataset, its overviews, and its item cache from disk. | |
Adds, replaces, or removes a function chain in a mosaic dataset or a raster layer that contains a raster function. | |
Creates a feature class showing the footprints, boundary, seamlines or spatial resolutions of a mosaic dataset. | |
Saves a copy of your processed images within a mosaic dataset to a specified folder and raster file format. | |
Creates a table of the file path for each item in a mosaic dataset. You can specify whether the table contains all the file paths or just the ones that are broken. | |
Masks pixels based on their color or by clipping a range of values. The output of this tool is used as an input to the Color Balance Mosaic Dataset tool to eliminate areas such as clouds and water that can skew the statistics used to color balance multiple images. | |
Modifies the geometry for the footprints, boundary, or seamlines in a mosaic dataset to match those in a feature class. | |
Groups multiple items in a mosaic dataset together as one item. | |
Removes selected raster datasets from a mosaic dataset. | |
Resets paths to source imagery if you have moved or copied a mosaic dataset. | |
Defines the defaults for displaying a mosaic dataset and serving it as an image service. | |
Splits mosaic dataset items that were merged together using Merge Mosaic Dataset Items. | |
Keeps your mosaic dataset up to date. In addition to syncing data, you can update overviews if the underlying imagery has been changed, generate new overviews and cache, and restore the original configuration of mosaic dataset items. You can also remove paths to source data with this tool. To repair paths, you need to use the Repair Mosaic Dataset Paths tool. |
An overview of the Block Adjustment toolset
Block adjustment is a technique used in photogrammetry. It is used to mosaic satellite images or aerial photographs for an area or a project. Block adjustment is the process of computing adjustment (or transformation) based on internal relationship between overlap images, ground control points (GCPs), a camera model, a DEM, and then appling the adjustment to the images within a block.
For more information about this, see Block Adjustment for Mosaic Datasets.
| Tool | Description |
|---|---|
Analyzes the control point coverage and identifies the areas that need additional control points to improve the block adjust result. | |
Combines control points to an existing control point table. | |
Applies the geographic adjustments to the mosaic dataset items. This tool uses the solution file from the Compute Adjustments tool. | |
This tool is used to compute the adjustments to the mosaic dataset. This tool will create a solution table that can be used to apply the actual adjustments. | |
Computes the control points between the mosaic dataset and the reference image. The control points can then be used in conjunction with tie points to compute the adjustments for the mosaic dataset. | |
Computes the tie points between overlapped mosaic dataset items. The tie points can then be used to compute the adjustments for the mosaic dataset. |
An overview of the Raster Dataset toolset
A raster dataset is the basic data model for rasters. A raster dataset is an organized array of pixels, which can have a single band or many bands. This toolset provides the tools to copy, create, or append raster datasets.
The following table lists the tools available in the Raster Dataset toolset and provides a brief description of each. The output for all these tools is a raster dataset.
| Tool | Description |
|---|---|
Saves a copy of a raster dataset or converts a mosaic dataset into a single raster dataset. | |
Create a raster dataset of random values with a distribution you can define. | |
Creates an empty raster dataset. | |
Downloads the source files from an image service or mosaic dataset. | |
Merges multiple existing raster datasets into an existing raster dataset. | |
Merges multiple raster datasets into a new raster dataset. | |
Merges all of the raster datasets in a folder into one raster dataset. |
An overview of the Raster Processing toolset
The Raster Processing toolset is used to perform some tasks to get your data to a workable form. The raster processing tools allow you to perform several tasks with your data to prepare it for analysis and display.
The following table lists the tools available in the Raster Processing toolset and provides a brief description of each. The input and output for all these tools is a raster dataset.
| Tool | Description |

Change the spatial resolution of your raster dataset and set rules for aggregating or interpolating values across the new pixel sizes. | |
Divides a raster dataset into smaller pieces, by tiles or features from a polygon. |
An overview of the Raster Properties toolset
A raster dataset has various properties that are associated with it: color maps, pyramids, statistics, attribute tables, world files, and cell values. The tools in this toolset help you create, delete, or edit the various properties that may exist for a raster dataset.
