Why use a GIS
- GIS are powerful tools
for handling large spatial databases.
- They have spatial and
temporal analysis capabilities.
- Data is maintained in
digital format so it is more physically compact than using paper maps.
- GIS can maintain and
retrieve large quantities of data quickly and can perform complex spatial
analyses quickly.
- They are useful in decision
making, assessing planning options, change detection and analysis.
- GIS is especially useful
because maps and other data are stored or filed as layers of information,
This makes it possible to perform complex spatial analyses. A data layer is
a set of logically related geographic features and their attributes.
