Geographic Information System (GIS) and satellite-based Remote Sensing (RS) have greatly improved our ability to collect, store, analyse and utilise geographical information. GIS and RS is a system of hardware, software and procedures designed for support, capture, management, manipulation, analysis, modelling and display of spatially referenced (geographical) data. The terms ‘geo-informatics system’ or ‘geomatics’ are used interchangeably. GIS and RS professionals finds career opportunities in environmental impact assessment, biodiversity assessment, natural resource management, environmental modelling, town planning, public utility work and many socio-economic development programmes. GIS professionals make the geographic information accessible to scientists, planners, decision makers, managers and to general public. The knowledge of geo-informatics is becoming a driving force behind the overall socio-economic development of the nation.
