79 Ø.1a Nioghalvfjerdsfjorden. Topographic map, 1:250 000

Topographic map of Greenland, 1:250 000, 79 Ø.1a Nioghalvfjerdsfjorden. 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.格陵兰岛1:250000比例尺地形图，编号79 Ø.1a 尼约尔法尔峡湾（Nioghalvfjerdsfjorden），分辨率400每英寸点数（dots per inch, dpi）。该系列彩色地形图比例尺为1:250000，等高距100米。整套53幅数字地形图覆盖格陵兰北部与东北部，西至英格尔菲尔德地（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。本系列地形图涵盖常规自然地理地貌要素，即海岸、河流、湖泊与冰盖。陆地与冰盖区域均采用100米等高距着色，并标注了精选的米级高程点。本系列地形图由丹麦国土测量局（Kort & Matrikelstyrelsen, KMS）基于航空照片，利用地面控制点与空中三角测量技术绘制完成。地图投影采用通用横轴墨卡托（Universal Transverse Mercator）投影，24带。本系列地形图为同比例尺地质图系列的续作，相较后者新增了覆盖英格尔菲尔德地与洪堡冰川（Humboldt Gletscher）的4幅副图。
