Question

A GIS analyst has two raster datasets with the same number of rows and columns. The analyst computes the average of the two input raster layers to generate a new raster layer with the same size as the input raster layers. What type of raster data analysis operation is performed?

• A. \( \text{Local} \)
• B. \( \text{Neighborhood} \)
• C. \( \text{Zonal} \)
• D. \( \text{Global} \)

Hint:

Local operations work on a cell-by-cell basis.

Answer 1

The Correct Option is A

The operation is local because the value of each cell in the output raster is computed using only the values of the corresponding cells in the input rasters.
