The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, Vol. 34, Part XXX International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, Volume XXXIX-B8, 2012 XXII ISPRS Congress, 25 August — 01 September 2012, Melbourne, Australia 2.2 Classification systems The classification system was developed based on what is possible to interpret from an aerial image and the needed of indicators describing the changes in the agricultural landscape. The classification for area is built up hierarchically with three levels for land type classes. A Agricultural land Al Fields of annual agricultural plants, and cultivated meadows A2 Horticultural land A3 Pasture A4 Pasture and hay meadows apparently no longer in use B Natural bare ground B1 Bare rocks, boulders and scree B2 Gravel, sand, earth and peat T Permantent unforested dry-land vegetation F1 Semi-natural grassland F2 Heaths and ridges F3 Maritim vegetation F4 Cleared forest F5 Outfield pasture M Natural, unforested wetland vegetation M1 Mire and other freshwater wetlands 2 Salt and brackish wetlands S Forest and three- covered land S1 Deciduous forest S2 Mixed forest S3 Coniferous forest U Built-up areas UI Transport U2 Buildings U3 Storage areas, dumps and rubbish tips U4 Urban greenways, sport and recreation areas U5 Other built-up areas V Water, snow and ice V1 Freshwater V2 Snow and ice V3 Saltwater and brackish water Table 1. Classification system for land type classes for the Norwegian land use / land cover monitoring program. Interpreted lines are: path, stone wall, fence, line of trees, line of bushes, vegetation line, ditch / canal, stream and high tens- ion cable. Interpreted points are: pile of stones, boulder, solitary tree, post in field, pylon, building, ruin and fish racks. Some of these are indicators for biodiversity and some are indicators for the experience of the landscape. For the accessibility we interpret pedestrian zone , path and road. The size of the square has proved to be too small to tell the accessibility in the agricultural landscape, but the changes can be measured and inaccessible areas are visible. 2.3 Software systems For the interpretation Summit software with a Planar mirror stereo view system is used. MicroStation is used for mapping. The data is converted into sosi-files (the Norwegian standard for vector data) and these sosi-files are checked for errors. Further quality check, storage and analyses of the data are now being carried out with the open source software PostgreSQL and PostGIS. 2.4 Field control 1096 of the squares are visited in the field and are used to verify the interpretation. The program are now in the second inventory cycle. The operator's interpretation has improveddue to several reasons: the photos are better, the skills of the interpreter have improved and the operators easier understand what they see on the ground when they can compare two photos with different dates. They see and understand the development of the area better (Engan, 2012).
