Abstract
Physical geography is, to a great extent, a fieldorientated subject, and therefore the registration of field data comprises an important part of the subject. In today's research great emphasis is placed on developing rational methods of registration and, in addition, on improving the theoretical basis for interpreting the elements which are registered. Greater demands are made on precise localization of registrations and on better techniques for representation. At the Department of Geography, University of Oslo, a laboratory has been built for remote sensing and thematic mapping, as well as geometries (data processing of localized information).
