GIS in use
Unlock the value of information stored in databases across your organisation.
Using 3D height data and map data for river features, you can build a computer model of changing water levels to predict flood patterns and identify areas in danger. By combining this model with address data, you can assess the flood risk to individual properties. This helps insurance companies price premiums with greater confidence, and infrastructure bodies to plan flood defences.
GIS can be used to record locations as part of a nature conservation project. It gives instant access to information about the geographical spread of sightings or plantings and lets users update information quickly and easily.
3D environmental impact analysis
3D landscape models help planners assess the impact on the local area of proposed developments such as wind farm or telecommunications masts. They also help companies behind the schemes model wind flow and signal propagation.
Restrictions on aircraft noise affect all busy airports. GIS can help you monitor both the noise and complaints from nearby residents. When new runways or flight path changes are proposed, you can model sonic impact on nearby built-up areas to identify how many properties are going to be affected by high noise levels. By logging the addresses of people who complain about noise, the airport can monitor the effectiveness of their noise control measures and compliance by airlines with their guidelines.
Here's how GIS is used in the public sector:
Utilities – leak management, service planning network planning;
Central government – census, environmental planning, health service catchment areas
Local government – refuse collection, street lighting, council tax collection
Emergency services – crime locations, route finding
