Services - Geographical Information Systems (GIS)
Below are examples of how GIS is used to evaluate various locations using individual criteria, and subsequently multiple criteria, to qualify or eliminate geographical areas.
The first map presents information relating to population by county. The second map presents an example of how counties can be screened based on specific project criteria for population, and counties can be either "qualified" or "eliminated". The third map introduces the variable of proximity to interstates. The fourth map combines the two criteria of population and proximity to interstates, and presents counties that have qualified under both criteria. The fifth map presents a range of manufacturing wages for counties previously qualified, and the sixth map presents a range of average hourly wages for counties previously qualified. The difference between maps five and six indicates the criticality of using the correct screening tools and interpreting them accordingly.
