Geological GIS data management

In the Norwegian Polar areas, geological data have been collected for many decades. Only since the 1980s, electronic media were used to produce maunscripts. Maps, photos, illustrations, etc. were not stored in digital formats earlier than the 1990s.

The rapid development of electronic applications like GIS (Geographical Information Systems) and Internet-based technologies has made it possible to organise data electronically in a way that facilitates applications and benefits large user groups. The aim of the project is to continually update electronic geological databases and to create an Internet user face. The project is an intra-institutional cooperation between the Polar Institutes Geological Mapping Programme (Geokart) and NPI’s Environmental Data Section.

Objectives

  • to combine all digital, geological map data of Svalbard within a seamless GIS database, compatible with NPI’s topographical map database;
  • to make the geological map database available on the Internet, in a GIS system with other sorts of systematized geological data like area/locality descriptions, photos, cross sections, stratigraphic logs, analytical results, etc.;
  • to apply international geo-coding standards and incorporate relevant map data into national and international databases (Norge digitalt, OneGeology, etc.).

Although continually worked at since the late 1990s, the project has met major obstacles like changing technical equipment and software, reconstruction of the topographic map database subsequent to geological mapping, non-existence of an internationally unified coding system, and lacking capacity at the Norwegian Polar Institute.
