Calculate Raster Statistics

 This processing task calculates statistics for raster and mosaic datasets. 

To run this task in the Navigo UI:

  • Cick the Queue icon and select New Task from the drop-down menu. 

  • Select Calculate Raster Statistics from the task menu

  • Enter a Horizontal Skip Factor
  • Enter a Vertical Skip Factor
  • Set a value for Ignore Pixel Values (Optional)
  • Click Run Task to begin processing

Supported File Types

This task supports Raster files.

Usage Tips

  • RECOMMENDED: See the ArcGIS help topics below for information about calculating statistics. Statistics are required for your raster and mosaic datasets to perform tasks such as reclassification. Statistics also  allow ArcGIS to properly stretch and symbolize raster data for display.
  • The Processing Extent is not supported for ArcGIS 10.0. It will be ignored and the full extent used.
  • A skip factor is not used for all raster formats. The supported raster formats include TIFF, IMG, NITF, DTED, RAW, ADRG, CIB, CADRG, DIGEST, GIS, LAN, CIT, COT, ERMapper, ENVI DAT, BIL, BIP, BSQ, and geodatabase.
  • The skip factors control the portion of the raster dataset that is used when calculating the statistics, where a value of 1 will use each pixel and a value of 2 will use every second pixel.
  • The skip factor values can only range from 1 to the number of columns/rows in the raster.
  • For mosaic datasets, the statistics are calculated for the top-level mosaicked image and not for every raster contained within the mosaic dataset.
  • Mosaic datasets tend to be very large and specifying a skip factor is highly recommended.
  • The Esri Grid and the RADARSAT2 formats always use a skip factor of 1.

Requirements

  • ArcGIS 10.x
