 Summary

CLIP RASTER TOOL
Input: a raster layer (and optionally: other reference layers)
Output: a new raster layer
Features:

  • clips a raster to an extent defined by a) another layer, b) a selected polygon in a layer, or c) coordinates supplied by the user
  • when clipping to the extent of another layer, allows the user to add a buffer distance to the extent of the layer
  • the new raster layer can be saved as a Grid, GeoTIFF or Imagine Image file
  • can be used with multi-band images

Limitations:

  • may not work with rasters stored in a geodatabase

 Example

Figures A & B. A raster layer with one band is clipped to the extent of a point layer (red dots) with a buffer of 100m added to the extent of the point layer.

 Help

Getting started. A raster layer must be loaded into ArcMap in order to use this tool. If you wish to clip to the extent of another layer (raster or vector) that layer must also be added to ArcMap prior to starting the tool. If you wish to clip to the extent of a polygon, a single polygon must be selected in a polygon layer prior to starting the tool.

Multiple bands. Raster layers in ArcMap display a maximum of 3 bands. A raster dataset on a disk can have more than 3 bands. This tool accesses the raster dataset on the disk to ensure that all the bands in the raster are retained in the new raster layer, not just the three bands that are loaded in ArcMap. The order of the bands is also retained in the new raster layer.
