An overview of the Extraction tools

The Extraction tools allow you to extract a subset of cells from a raster by either the cells' attributes or their spatial location. You can also obtain the cell values for specific locations as an attribute in a point feature class or as a table.

The tools that extract cell values based on their attribute or location to a new raster include the following:

The tools that allow you to specify the locations for which to extract cell values to an attribute table or a regular table include the following:

The following table lists the available Extraction tools and provides a brief description of each.

Tool

Description

Extract by Attributes

Extracts the cells of a raster based on a logical query.

Extract by Circle

Extracts the cells of a raster based on a circle.

Extract by Mask

Extracts the cells of a raster that correspond to the areas defined by a mask.

Extract by Points

Extracts the cells of a raster based on a set of coordinate points.

Extract by Polygon

Extracts the cells of a raster based on a polygon.

Extract by Rectangle

Extracts the cells of a raster based on a rectangle.

Extract Multi Values to Points

Extracts cell values at locations specified in a point feature class from one or more rasters, and records the values to the attribute table of the point feature class.

Extract Values to Points

Extracts the cell values of a raster based on a set of point features and records the values in the attribute table of an output feature class.

Sample

Creates a table that shows the values of cells from a raster, or set of rasters, for defined locations. The locations are defined by raster cells or by a set of points.
