Geographic Information Science focuses on four domains: people, database technology, software, and systems applications. The first domain--people, is an evaluation of different customer communities as end users and the GIS manager who designs/customizes the systems for interdepartmental and general customer services. Database addresses the nature of a geographic information systems application in diverse information engineering platforms. Software is a focus of choice on scientific and technological innovations that best support the client, data processing and server systems. The domain of systems applications is a challenge of analytical and presentation skills for the GIS team relative to the tasks the team wants to accomplish with the systems in a geographic area. A GIS cannot answer to all geospatial needs. However, the following concentrations are offered: Homeland Security, Natural Resources Management.

An increasing number of firms are interested in geographic information and its applications. For example, GIS can be used to create maps and information used in emergency planning, security, marketing, urban planning, natural resource exploration, construction, and other applications. Also, the increased popularity of online mapping systems has created a higher demand for and awareness of geographic information among consumers.
