Data for "Proposal of an algorithm-independent definition of effective contour length (EL) and its impacts on pixel-scale specific catchment area (SCA)"

This dataset is used for the paper of "Proposal of an algorithm-independenat definition of effective contour length (EL) and its impacts on pixel-scale specific catchment area (SCA)". Therein, 'ellipsoid.txt', 'inverse ellipsoid.txt' and 'Saddle.txt' record the DEMs discretized from ellipsoid, inverse ellipsoid and saddle, respectively. 'Real-world DEM' records the DEM of the YiLuo River basin with a horizontal resolution of 100m and vertical resolution of 1m
