Data Quality
This geotif is derived from Digital terrain model of Denmark at 0.4m x 0.4m resolution (Spec_DHM/T_V2.0, Danish Agency for Data Supply and Efficiency). The 1km tiles were merged and resampled from 0.4 x 0.4 m to 100 x 100 m with upscaling option “Mean Value (cell area weighted)”. The slope was calculated and reclassified to T index value using the HOVER D7-2 Appendix A1. The pilot area takes the values between 3 and 10. See HOVER D7-2 for more details and references.
