GIT (Information technology)
GIT is based on digital systems used to register, model, analyse and present geographically referenced data.
These data are digital representations of phenomena in the real world. A GIT database contains two types of data: (1) Spatial data such as a road, height, borehole and so forth, and (2) appurtenant attribute data.
NGI actively uses GIT in environmental mapping and hazard (e.g. landslides, avalanches) assessment, both as an aid in the analyses and for the presentation of results.
NGI's state-of-the-art expertise:
- data management and standardisation
- modelling and 3D visualisation
- remote sensing of geohazards
Services related to GIT
GIT is utilised in many of NGI's professional fields. Visualisation and animation in 3D are used to illustrate the extent of for example marine pollution, among other things.
NGI can run analyses at different geographical levels: global, regional and local. For example, we use GIT models to predict landslides due to earthquakes, and snow stability on the basis of terrain formations and precipitation.
Research and development
The challenges and NGI's research in connection with GIT include:
- traditional GIT analysis
- grid analysis
NGI is also working with how remote sensing can be used towards natural hazards.
