What is GIS?
Geographic Information Systems (GIS) integrates hardware, computer software, and data for capturing, managing, analyzing, and displaying, in visual formats, all forms of geographically referenced information.

GIS allows not only SRTC staff, but also staff at our partner agencies and members of the public, to view, understand, question, interpret, and visualize data in many ways.  GIS products (maps, globes, reports, and charts) reveal relationships, patterns, and trends that may not be obvious when viewed as raw data. GIS helps answer questions and solve problems by looking at data in a way that is quickly understood and easily shared.

SRTC has two Geographic Information Systems Analysts on staff.  They support SRTC’s core functions through model data input (land use and forecast data), geospatial analysis, and creation of cartographic products, such as maps and charts.

For more information on Geographic Information Systems, and resources, go to the website.
