GRID ANALYSIS

Mathematical Calculations

You can perform mathematical calculations on grids to modify or filter the information in a single grid or generate new grids from two or more existing grids.

In this example, the units of an elevation grid are converted from meters to feet. This involves multipling every cell in the grid by a conversion factor.

A more complex example is the normalization of grid values to a specific range, such as between one and zero. This is useful when you want to determine the relationship between two datasets that have different units as well as a different range of values, for example, elevated blood lead levels and average family income.
