Vinnan fer fram við Polar Geospatial Center ( PGC ) sem er innan veggja Minnesota háskóla . Þær myndir sem notaðar eru til verkefnisins eru yfirleitt 2 - 3 ára en allt að 6 - 7 ára gamlar . Gögnin innihalda landhæðarlíkan ( 2 - m-greinihæfni ) , 2 - m-hæðarlínur og hæðarskyggingu ( hillshade ) . The DEM is based on satellite imagery of stereo-pairs from satellites such as WorldView - 1 , WorldView - 2 , WorldView - 3 and GeoEye - 1 that have a resolution of 31 - 46 cm . Although the data is generally of high quality there is , however , need to carry out considerable work to eliminate clear defects . The National Land Survey has acquired the data and presently work is conducted on gap filling , elevation cone removal and geoid corrections and the Herðubreið DEM is an example this work . The Herðubreið data set consists of a digital elevation model with 2 m resolution , 2 m contour line data set and a hillshade made from the model . The model is mainly based on a WorldView - 1 satellite image obtained on July 16 th 2012 .
