Geographic Information Systems (GIS)
What is a GIS?
A GIS is a system for capturing, handling, analysing, and displaying spatially referenced data. Typically the output from a GIS is some form of graphic display or map. The input is gathered from a variety of sources including, paper based maps, digital map products, satellite images and aerial photographs. The information, once obtained, is converted (if required) and stored in a digital format for ease of manipulation. The data is integrated to a common reference allowing a final product to be produced which combines required information from the individual source data types.
What is involved?
GIS's come in a variety of flavours from basic systems running on a standalone PC to large applications requiring a supercomputer to manipulate very large datasets. Hardcopy data types (paper maps etc) are converted to digital format using a scanner. Several software programs are used to "clean" the data and to merge the diverse formats. If hardcopy output is required a printer or plotter is used.
What are the advantages?
Because of its digital format, data used by a GIS for one project can be easily reused and reinterpreted. Changes can be incorporated easily.
The GES GIS Laboratory has been set up to provide our students with a solid grounding in all facets of GIS.
