Slope Length and Stepness Factor Dataset of Pan-Third Pole 20 countries (2020, with a resolution of 7.5 arcsecond)

Slope Length and Stepness Factor Dataset of Pan-Third Pole 20 countries (2020, with a resolution of 7.5 arcsecond)


The Slope Length and Stepness Factor (LS) dataset of Pan-third pole 20 country is calculated based on the free accessed 1 arc second resolution SRTM digital elevation data (Shuttle Radar Topography Mission, SRTM; the website is http://srtm.csi.cgiar.org). After the pre-processing such as pseudo edge removal, filtering and noise removal, the LS factor with 7.5 arc second resolution was calculated with the LS factor algorithm in CSLE model and the LS calculation tool (LS_tool) developed in this project. The LS factor data of Pan-third pole 20 countries is the fundamental data for soil erosion rate calculation based on CSLE, and it also the fuandatmental data for analyzing the erosion topographic characteristics of Pan third pole 20 countries (such as macro distribution and micro pattern of elevation, slope and slope) . The dataset if of great importance for the analysis of geomorphic characteristics and geological disaster characteristics in this area.


File naming and required software

XDA200402022-20G-LS.zip, where XDA20040202 is the subject number;2 is the sub-subject number;20G represents 20 countries;and LS represents the slope length factor. The data is in TIFF format, which can be opened and analyzed by general GIS software (such as ArcGIS) or image processing software (such as ENVI).
