THE MAPPING OF NORTHERN GREENLAND
Abstract Approximately 110 sheets of orthophotomaps at a scale of 1:100000 covering all the ice, free area (300000 km 2 ) of northern Greenland are to be produced by the Geodetic Institute of Denmark. Super‐wide angle photography at a scale of 1:150 000 was acquired in 1978. Individual models are se...

| Summary: | Abstract Approximately 110 sheets of orthophotomaps at a scale of 1:100000 covering all the ice, free area (300000 km 2 ) of northern Greenland are to be produced by the Geodetic Institute of Denmark. Super‐wide angle photography at a scale of 1:150 000 was acquired in 1978. Individual models are set up in a Wild B8S stereoplotter and, after carrying out aerial triangulation, a numerical method of absolute orientation is used. A digital ground model of the entire area is established in order to enable the interpolation of contour lines, for automatic plotting and to produce control data, for the orthophotoprojector. a Wild OR1. Methods of data handling and control, accuracies and typical errors are discussed. |
