摘要：The Geodetic Institute of Denmark has started a mappingproject in the northern parts of Greenland. The mapping isto be based on a production of numerically controlled orthophotoswith superimposed contourlines.Approximately 110 sheets of orthophotomaps on the scaleratio of 1:100,000 covering all JOO,OOO km2 of the ice-freepart of Northern Greenland are to be produced.A special photo mission with super wide-angle camera andan image scale of 1:150,000 was carried out in 1978. The individualmodels are scanned in an Wild Aviograph B8 Sand,after an aerotriangulation, absolute orientated numerically.A digital terrain model of the whole area is established toform the base, partly of calculation of contourlines for automaticplotting, and partly of production of control datafor the orthophotoprojector, Wild Avioplan ORl.Data-handling and control, accuracies and typical errorsare discussed.
