Dataset Abstract

These files are used to interpolate the data from the relief profile of Xingangshan, experimental site A into a 3D-model. For this, "ESRI ArcGIS shapefile" has been used. Additional and more detailed describtions can be obtained from "Sampling description".
Explanantion of DTA (digital terrain analysis) for Xingangshan, experimental site A:
- data are stored as ESRI ArcGIS shapefile
- all data on slope and apect[1] are given in 'degrees'
- data contain 2 algorithms to calculate slope: mSlope = mean slope[2], sSlope = steepest slope[3]
- standard deviation has been calculated for elevation and for mean and steepest slope as parameter which describes the terrain based heterogeneity of the plots
- DGM (*.asc) and shapefile are according to WGS 84
Ordinary Kriging (Spherical), ConvexHull clipping algorithm
Quality: Rsquared 0.99 RMSE 1.8 m (10-fold cross-validation)
Datasets: Koord.txt (origin, ALLSAT), points.txt (preprocessed), dem5_final.asc (final dem, common ASCII SharedDataFormat), description.txt
Notes: boundary effects based on the interpolation method and the clipping algorithm
