What is GIS?
The four major components of a GIS are: |
 |
HARDWARE – used to store, process and display digital map data |
|
SOFTWARE – performs GIS operations |
|
DIGITAL MAP DATA – manipulated and managed by the GIS |
|
PROCEDURES – followed to perform various operations |
|
|
| A
GIS has four general functions: |
|
INPUT – digitizing, editing, data reformatting, etc. |
|
ANALYSIS – overlay, buffering, querying, modeling, etc. |
|
DATA MANAGEMENT – handling of large sets of geographic or cartographic data; overseeing storage and retrieval of same. |
|
DISPLAY AND CONVERSION – graphic output (maps, plots), reports, tabular data, etc. |
|
|
| A
GIS is used to automate, manipulate, analyze and display geographic
(spatial) data in digital form. There are two generic classes
of spatial data: |
|
Locational
data: describes the location (coordinates) and topology
(spatial relationships) of geographic features |
|
Attribute
data: describes the characteristics of these features
Attribute data is linked to locational data by common feature numbers which occur in both coordinate/topology data tables and attribute data tables.
