- What is GIS?
- A Geographic Information System (GIS) is a computerized marriage between a graphic
representation and a textual description of a geographic location. A GIS provides the decision maker
with a logical and graphic representation of geographically referenced information.
- A GIS can maintain, analyze, and report on:
- geographical data, such as points and symbols, lines and curves or polygons,
attribute data, such as: characters, numbers or dates.
- A GIS can provide accurate answers to geographic questions such as:
-
Where is a feature located?
What is it adjacent to?
What is its relationship to other features.
A GIS provides a powerful, logical, and intuitive means to store, manipulate, and retrieve
data. It provides the ability to see on screen or in map form, only those features or
objects that meet specific selection criteria. In an instant, you can visually identify
features in a geographic representation that would take much longer to find in a printed
report.
