GRID ANALYSIS

Point Inspection

You can analyze a grid by querying locations on a map to obtain each location's grid value. You can also obtain information on more than one grid if several overlap geographically. In the example below, grid values from a tornado density map of the United States are queried, based upon observations between 1950 and 1995.

You can also update the database of a point file with grid information for each point location. For example, an insurance company can update policy holder point files with elevation values from a digital elevation model (DEM). In doing so, insurance agents can better determine the location of those policy holders who may be at a higher risk of flooding.
