Answer explanation

The following statements about GIS' uses in spatial analysis are true, except:

• It provides the means to model geographic problems, derive results through computer processing, and add value to geographic data

• Its role is more focused on providing static geographic information rather than actively contributing to the modeling and derivation of results in spatial analysis

• It enables the spatial analysis process, allowing users to understand the location of events, measure sizes and distributions of geographic features, and perform a wide range of spatial analysis functions
