These Surveyors use Geographical Information Systems (GIS) which are computerised systems that map data relative to a physical location, in the production and analysis of geographical data to support and deliver services such as: healthcare, environmental management, urban planning, defence, construction, transport planning, demographic marketing, utilities provision, exploration and mining.
GIS involves layering data about a particular site where the land survey is the first layer, providing a platform for additional layers that give more detail such as roadways, vegetation, ground water, manmade items, population, etc. The GIS officer/analyst can then provide relevant information about this site using the various layers as required.
The use of GIS is growing mainly due to new technologies that store, display, analyse and map information and as such GIS officers/ Analysts may find themselves working in a range of fields from government agencies to large private developers in need of GIS studies.
GIS officers may perform the following tasks:
- Capture exact location of 'assets' using GPS (global positioning system) tools in the field, e.g. location of buildings, street lamps, roads and so on for private companies, government agencies and local authorities;
- Desk-based data capture (digitising) to convert paper maps to GIS datasets;
- Create and maintain the structures necessary for GIS data storage;
- Develop the tools for loading/transferring GIS data between different system;
- Create programs to convert GIS information from one format to another;
- Develop internet applications to present GIS data and tools on corporate websites;
- Use tools to join together different GIS datasets and create new information or investigate patterns, e.g. using population growth figures and planning information to estimate increasing/decreasing demand for schools;
