A generalization operation that produces an output raster with a larger cell size (i.e., a lower resolution) than the input raster.

A mask that limits raster data analysis to cells that do not carry the cell value of no data.

A neighborhood operation that uses a rectangle (block) and assigns the calculated value to all block cells in the output raster.

Distance measured by the cost of impedance of moving between cells.

A cell-by-cell raster data operation.

A term referring to algebraic operations with raster map layers.

A raster data operation that can piece together multiple input rasters into single raster.

A raster data operation that involves a focal cell and a set of its surrounding cells.

Straight-line distance between cells.

A raster data operation that calculates straight-line distances away from the source cells.

An operation that uses a data set, a graphic object, or a query expression to extract data from an existing raster.

A local operation that reclassifies cell values of an input raster to create a new raster.

A raster data operation that divides a continuous raster into equal-interval or equal-area classes.

A raster data operation that involves groups of cells of same values or like features.
