Spatial Data Infrastructure
A spatial data infrastructure (GDI) is a systematic collection of geodata and services related to geodata. The Liechtenstein government recognized the importance of geographic information as early as 1994 and decided to create a systematic collection of geodata. Since then, the Liechtenstein Spatial Data Infrastructure has been coordinated and further developed by the Office of Civil Engineering and Geoinformation and the Office of Information Technology.
The main tasks are the coordination of the various parties involved (state, municipality, Pipeline operators), the creation of concepts and data models, data collection, tracking, management and long-term maintenance of the geodata.
Geodata
Geodata refers to data about objects that are directly or indirectly identifiable according to their position in space. Geodata are presented to the user mainly in the form of maps and plans. Known examples of products from the spatial data infrastructure are
- Land maps
- Aerial photographs (orthophotos)
- Plan for the land register
- Zoning plan
Organizational frameworks, technical guidelines and an IT infrastructure are as necessary for the development and maintenance of a spatial data infrastructure as the data themselves. The goal is to ensure the broadest possible use of geospatial data by a wide range of users.
