Digital Photogrammetric Map Data of the Framnes Mountain Region taken from 1:45000 1996/97 aerial photography. Data Layers consist of building, contour, geology (erratics only), human, spot_height, survey, topoline, topopoly and toposurf.
All exposed visible listed features in the vicinity of the Framnes Mountains were captured. Intermediate area of continental ice between the Mountain ranges were not mapped. Some areas obscured by cloud were also not mapped. Listed features include boundaries of bedrock, scree, moraine and continental ice, nunataks, crevasses and crevasse fields, rock and ice cliffs, flow lines, drift tails, ... streams, lakes, melt lakes, melt streams, ice hillocks, blue ice, refuges, ridge lines, spot heights and snow covered areas. Data captured from 1:45000 colour aerial photography of various dates during March and April 1996. Photography controlled using sparse ground survey marks of class and order c3 which was supplemented by Aerial Triangulation (Bingo Bundle Adjustment). Photo Control accuracy varies between regions but is all better than 1 metres. The data were captured using a Zeiss P2 analytical stereo plotter and Microstation version 5 on a universal transvese mercator grid. The polygon data were edited, cleaned and polygonized using Arc/Info. Maximum fuzzy tolerance for cleaning was 0.01 metres. The data were also generalized using a tolerance of 0.1 metres. The value tests for the data set include a test for spatial accuracy and data completeness, including line and point errors a test of valid values against the data model a visual check to hard copy material.
Data stored as Arc/Info coverages and export files and ASCII files. Stored as geographicals with a projection file.
