GIS is a collection of computer-based tools created for the organization of information from a variety of data sources aimed to map and examine changes on Earth.
It’s designed to capture, store, manage, analyze, and visualize all types of geographical data, and allow the integration and collective analysis of geospatial data from multiple sources, including satellite imagery, GPS recordings, and textual attributes associated with a particular space.
GIS technology integrates common database operations such as statistical analysis, with maps. GIS manages location-based information and provides tools for display and analysis of various statistics, including population characteristics, economic development opportunities, vegetation types, etc…
GIS allows you to link databases with maps to create dynamic images; it works through the Remote sensing , the art and science of making measurements of the earth using satellite-based sensors.
Remotely sensed data, integrated within a GIS, can be visualized to obtain information about the data; in addiction a GIS provides specialized capabilities for manipulating and analyzing those images.
Now you have an idea of what GIS is. Do you image what can you do with it?
