Liangshan Mountain is located in Sichuan Province of China. The Dataset of Mountain Characteristic Elements in Liangshan Mountain was developed based on the SRTM3 DEM 90 m data by algorithm for the integration of mountain peaks, ridge lines and control areas. Then the results were combined with that by fuzzy membership analysis methodology. The dataset is consisted of: (1) boundary of Liangshan Mountain; (2) main mountain area; (3) main ridge lines; (4) ridge lines obtained by fuzzy membership; and (5) contours data at 100 m intervals. The dataset is archived in .shp, .tif and .txt data formats, and consists of 55 data files with data size of 29.6 MB (Compressed into one single file with 14.9 MB). Τhe research paper related to the dataset was published at the Journal of Geo-Information Science, Vol. 22, No. 3, 2020.Browse
