Aggregate
A generalization operation that produces an output raster with a larger cell size (i.e., a lower resolution) than the input raster.
Analysis mask
A mask that limits raster data analysis to cells that do not carry the cell value of no data.
Block operation
A neighborhood operation that uses a rectangle (block) and assigns the calculated value to all block cells in the output raster.
Cost distance
Distance measured by the cost of impedance of moving between cells.
Local operation
A cell-by-cell raster data operation.
Map algebra
A term referring to algebraic operations with raster map layers.
Mosaic
A raster data operation that can piece together multiple input rasters into single raster.
Neighborhood operation
A raster data operation that involves a focal cell and a set of its surrounding cells.
Physical distance
Straight-line distance between cells.
Physical distance measure operation
A raster data operation that calculates straight-line distances away from the source cells.
Raster data extraction
An operation that uses a data set, a graphic object, or a query expression to extract data from an existing raster.
Reclassification
A local operation that reclassifies cell values of an input raster to create a new raster.
Slice
A raster data operation that divides a continuous raster into equal-interval or equal-area classes.
