WHAT IS GIS MAPPING?
Department Contacts
A Geographic Information System (GIS)
combines layers of information about a particular location
to give you a better understanding of that location. The layers of information
might represent features on the ground such as: rivers, streams, roads, gas
stations, restaurants, etc. Which layers of information you combine depends on
your purpose - finding the best location for a new store, analyzing
environmental damage, viewing similar crimes in a city to detect a pattern, and
so on.
GIS is a computer-based tool that provides the capability to
do mapping and geographical analysis of Earth's features and events. Using GIS,
dissimilar data can be related on the basis of common geographic location,
creating new information from existing data resources.
Most data contains a geographical component: an address,
census tract, zip code, city, county, or latitude/longitude coordinate.
GIS software lets you see, explore and analyze data by
location, revealing hidden patterns, relationships and trends that are not
readily apparent in typical spreadsheets, database tables and reports, or
statistical packages.
GIS can produce beautiful maps and is a dynamic system that
allows you to select and remove any criteria on the map to quickly analyze how
different factors affect your model and ultimately make informed decisions for
complicated problems.
