Raster Analysis

A large volume of spatial data exists in raster form, such as scanned thematic maps, and remotely sensed images. Classified images, and thematic maps are analyzed using the raster analysis module. With the help of this module basic arithmetic functions (like addition, subtraction,etc), regrouping (class and range) of raster files and various other operations can be carried out.

This module performs following functions:

• Map algebra to combine multiple maps using arithmetic, logical, and relational operators, nested if-then conditions etc.
  
• Conditional and unconditional overlay of maps.
  
• Buffer generation and distance calculation.
  
• Zonal, focal, neighbourhood operations and Watershed delineation.
