The project covers photogrammetric mapping of 250,000 square kilometres of Greenland's south west coastline from historical aerial photography flown in 1985.
Apart from new digitising and interpretation of the coastline, ice flows and glaciers, existing data will be incorporated to KMS specifications.
COWI Mapping UK has used transformed KMS triangulation results to adjust the scanned images into the project system GR96 UTM zone 24 MSL (Mean Sea Level) by combining new aerial triangulation observations with historical KMS observations.
Accuracy specifications
Despite this mix of historical adjustment, the positional accuracy and sea levels have met defined accuracy specifications.
The final data set of orthophoto mosaic, vector mapping and contours will be used for the positional correction of the Hydrographic Chart series.
