Geographic Information Systems (GIS) are involved with the capture, storage, manipulation, retrieval and display of spatial data. Spatial data refer to objects on the earth’s surface which have horizontal/2D coordinates, often with a 3rd (vertical plane/3D) and 4th dimension (time). Different data types are used to portray the objects, each suitable for different phenomena. This data can then be studied and/or combined to reveal spatial relationships and produce answers to questions in this regard.

Remote Sensing (RS) refers to data types which are captured from a distance or remotely ‘sensed’, e.g. aerial photographs and satellite pictures. These pictures have different characteristics in terms of spatial, spectral, and temporal resolution. As such, these data types have different applications depending on the client’s requirements. In some instances the high level of detail, characteristic of aerial photographs or high-resolution satellite images, permits landuse/landcover mapping based on visual interpretation. Other data sources, notably satellite images with a high spectral resolution, allow data extraction from the images by manipulation of the different bands. Processes include spectral enhancement of images to distinguish between different features, or the matching of spectral response curves to satellite sensor bands in order to identify certain objects/materials.
