77 Ø.1a Qeqertaq Prins Henrik. Topographic map, 1:250 000

Topographic map of Greenland, 1:250 000, 77 Ø.1a Qeqertaq Prins Henrik. 400 dpi. Coloured maps at 1:250 000 with contour interval 100 m. A set of 53 digital maps covers North and North-East Greenland from lnglefield Land in the west to Scoresby Sund in the east. One additional sheet provides an index map and a legend. The maps show the usual range of physiographic features, viz. coasts, rivers, lakes and ice. They are coloured with a 100 m contour interval over both land and ice, and with selected spot heights in metres. They have been drawn at the Survey from air photographs using Kort & Matrikelstyrelsen (KMS) ground control points and aerotriangulation. Map projection is Universal Transverse Mercator, zone 24. The maps are a sequel to a set of geological sheets at the same scale but with four extra sheets covering lnglefield Land and Humboldt Gletscher.

本数据集为格陵兰地区1:250000比例尺彩色地形图，其中编号77 Ø.1a的图幅覆盖亨利克王子岛（Qeqertaq Prins Henrik）区域，整体分辨率为400dpi，等高距为100米。整套53幅数字地形图覆盖格陵兰北部及东北部区域，西起英格尔菲尔德地（Inglefield Land），东至斯科斯比松（Scoresby Sund）。另有1幅副图包含索引地图与图例。该系列地形图涵盖各类常规地貌要素，包括海岸、河流、湖泊与冰盖。陆地与冰盖区域均采用100米等高距配色方案，并标注精选的米级高程点。本系列地形图由丹麦国家测量局（Kort & Matrikelstyrelsen，简称KMS）利用地面控制点与空中三角测量技术，基于航空摄影资料绘制完成。地图投影采用通用横轴墨卡托（Universal Transverse Mercator）24分带坐标系。本系列地形图为同比例尺地质图幅的后续补充系列，新增4幅图幅覆盖英格尔菲尔德地与洪堡冰川（Humboldt Gletscher）区域。
