Raster Analysis

Cost distance

Calculate the least accumulative cost path from source cell to target cell

Raster overlay

Allowing us to combine several grids and produce a new raster layer

Raster calculator

Uses boolean and arithmetic operators to select areas of interest

Raster mask

Allows selection of pixels from one grid based on pixels from another grid when we are overlaying raster data

Mask grid

Must be binary (0,1)

Local functions

Works on a cell in a single location

Focal functions

Work on cell locations within a neighbourhood

Zonal functions

Work on cell locations within zones

Global functions

Work on all cells within the raster

Application function

Those that preform a specific applications (i.e. hydrologic analysis function)

Raster to vector conversion

All neighboring cells are connected to each other to determine line or polygon limits with points becoming the centre

Vector to raster conversion

The value of each cell is based on the value of one selected field (error prone)
