Define Mosaic Dataset NoData (Data Management)

ArcGIS Pro 3.4 | | Help archive

Summary

Specifies one or more values to be represented as NoData.

Usage

  • NoData can be used to define pixel values that surround an image; however, the mosaic dataset can be made more efficient if the footprints are recomputed to remove these boundary areas. To recompute the footprints you can edit them manually or use the Build Footprints tool.

  • You can specify multiple NoData values with the Bands For NoData Value parameter. Use a space delimiter between each value you want to define as NoData.

  • This tool inserts the Mask function within the function chain for each raster item within a mosaic dataset.

Parameters

LabelExplanationData Type
Mosaic Dataset

The mosaic dataset where you want to update the NoData values.

Mosaic Layer
Number of Bands

The number of bands in the mosaic dataset.

Long
Bands for NoData Value
(Optional)

Specify the NoData value for each band. Each band can have a unique NoData value defined, or you can use the same value for all bands. Choose the band from the drop-down list and then enter a value or multiple values. If you choose multiple NoData values, separate each value with a space.

If the function chain for each raster within the mosaic dataset contains the Composite Bands function, or if your raster data was added with a raster type that adds the Composite Bands function to each raster's function chain, then any value you specify will apply to all bands.

Value Table
Bands For Valid Data Range
(Optional)

Specify a range of values to display for each band. Values outside of this range will be classified as NoData. When working with composite bands, the range will apply to all bands.

Value Table
Query Definition
(Optional)

An SQL statement to select specific raster in the mosaic dataset. Only the selected rasters will have their NoData values changed.

SQL Expression
Composite NoData value from each band
(Optional)

Choose whether all bands must be NoData in order for the pixel to be classified as NoData.

  • Unchecked—If any band has pixels of NoData, then the pixel is classified as NoData. This is the default.
  • Checked—All bands must have pixels of NoData for the pixel to be classified as NoData.
Boolean
