One of the main features of a GIS is the ability to attach database information to spatial features e.g. a drainage pipe or gas main. Each feature type is represented by a layer. Layers of information are added to the GIS and they are then viewable from one source, allowing easier management and interrogation of data.

Numerous types of data can be used in a GIS – geological data, utilities, site work areas, Ordnance Survey mapping, pylons, road networks, postal codes and other spatial features (both above and below ground). Any additional data can be layered into the system (such as voice recordings, video footage and photographs) depending on the specification required by the client.

Data is captured in the field using rugged hardware and software specific for GIS data collection. A variety of digital data collection methods can be used e.g. GPS (Global Positioning Systems), Total Station lasers or Disto.

GIS allows real world and real time scenarios to be modelled, giving relevant data to the user more effectively than non-geographic solutions. 40SEVEN can provide data in a number of GIS packages and over the internet on the GIS DataView web site.

40SEVEN can provide a number of GIS solutions for your industry sector. GIS can be used in the following:
