The ITT Geographical Information System (GIS) serves the citizens of Santa Fe by providing a computer system designed for capturing, storing, integrating, analyzing and displaying data from a geographic perspective. GIS is comprised of the following elements:
- Technology that is used to analyze features that make up the earth's surface
- System that includes software, hardware, data, and personnel
- Use of the relative location of features in x, y, and z space to establish relationships between features
Typically, GIS stores information in themes or layers that hold data about a particular kind of feature. Each layer is linked to a specific position on the globe
GIS organizes geographic data into a series of thematic layers and tables. Because data in a GIS are referenced to geography, they have real-world locations and could overlay one another. GIS links the location to each layer (such as people to addresses, buildings to parcels, or streets within a network) to give a better understanding of how the features interrelate.
In a GIS, collections of geographic features are organized into data sets, such as land parcels, fire locations, buildings, orthophoto imagery, and raster-based digital elevation models (DEMs). Precisely defined geographic data sets are critical for useful geographic information systems, and the layer-based concept of thematic collections of information is critical for GIS data sets.
