How does each cell obtain a value?
There are three basic steps involved in transforming points into a continuous grid surface of values.
|
|
|
-
Before you begin, the point file must have a numeric attribute for each point
location, such as soil chemistry values, field strength levels, or the
number of crimes committed.
-
A grid of empty cells is spatially overlaid on the point file.
-
Each cell is attributed with a value calculated from the surrounding points.
