Description
An overview of the components of Geographic Information Systems (GIS). Database management in the context of spatial data. Data acquisition techniques including overviews of digitising, scanning, field survey and remote sensing. Data conversion process, visualisation of geospatial data, cartography, colour and 3D views. Concepts and definitions of spatial information systems, coordinate systems, mapping and spatial issues, data structures including vector, raster and surface modelling. Inputting both spatial and attribute data to the GIS. Transformation of data between coordinate systems, re-projection of map coordinates. GPS-based image registration. Editing data and creating topologically clean data. Tagging spatial data with attributes, linking spatial data to attribute databases. Use of basic analysis functions: spatial selection, attribute selection, making reports of spatial and attribute data, interfacing to the system using a high level language. Use of the World Wide Web to disseminate information.
