This reference data supports the work of the Digital Elevation Model Intercomparison eXercise (DEMIX) working group (Strobl and others, 2021; Guth and others, 2021; Bielski and others,2023). The da
The DEMs discretized from different synthetic surfaces. Three types of synthetic surfaces are involved in this datasets, and four sets of parameters are considered for each type of synthetic surface.
This data set was created for section 2.4 of Guth and others (2025) to show how the test tiles in the latest DEMIX database (version 4) provide a representative sample of the earth’s diversity. The f
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, 'ellips
