DHI Tools

Python tools for working with DHI MIKE21.

Features:

• Interpolate multiple raster DEMs directly to .mesh file
• Read and analyse .dfsu files
• Create .dfsu roughness map (or any other map) directly from .shp and .mesh
• Read and analyse .dfs0, .dfs1, .dfs2 files

Due to depending on the MIKE SDK DLL libraries only Windows is supported.

Install

Requirements
