GEOGRAPHICAL INFORMATION SYSTEMS (GIS)
GIS is a special-purpose digital database in which spatially referenced data is
stored in a common coordinate system.
A GIS enables:
• Data input, from hard copy maps, aerial photos, satellites, surveys, and other
sources
• Data storage, retrieval, and query
• Data transformation, analysis, and modeling, including spatial statistics
• Data reporting, such as maps, reports, and plans
GIS provide powerful tools for addressing geographical and environmental
issues by enabling integration of data from different sources and in different
formats and through appropriate query and analysis new datasets can be
generated.
Real examples of GIS application include finding shortest routes in a road
network, performing land suitability mapping and establishing the relationship
between incidence of disease and geology of an area among others.
The ability to use Remote Sensing data for GIS further enhances the
usefulness of the technology because accurate and up-to-date data can be
used for analysis and representation.
