/* DATA DESCRIPTION: Citation: Jacobs, Joachim; Weber, Klaus; Siegesmund, Siegfried; Bauer, Wilfried; Spaeth, Gerhard; Thomas, Robert J (2004): Geological map of COTTONTOPPEN, Heimefrontfjella, Antarctica (Scale 1:25,000). Alfred Wegener Institute for Polar and Marine Research, Bremerhaven; Institut für Geologie und Dynamik der Lithosphäre, Göttingen; Bundesamt für Kartographie und Geodäsie, Frankfurt, PANGAEA, https://doi.org/10.1594/PANGAEA.138778 Abstract: Topographic data of this geological map were obtained through stereoscopic aerial photo interpretation. The photogrammetric photo flights were undertaken in 1986 by the Institut für Angewandte Geodäsie, Frankfurt. Horizontal ground control points required for aerial photo interpretation were determined by means of Doppler satellite observation during the 2nd German Neuschwabenland Expedition 1985/86. Vertical ground control points were taken from unpublished map drafts at 1:100 000 scale by Norsk Polarinstitutt, Oslo. The elevation above mean sea level was transferred to Heimefrontfjella barometrically. For this reason assertions concerning the absolute elevation (referred to sea level) are uncertain. Contours and spot heights presented on the map were obtained from the photogrammetric evaluation of the photography taken in 1986; relative elevation data (hight differences) are accurate to approximately ±10 m.
