ICON Mesh

この例では、非構造化三角形メッシュをレンダリングする方法を示します。

📋 まとめ

Creates a mesh from 2D latitude and longitude unstructured cell bounds.

The resulting mesh contains triangular cells.

It uses Icosahedral Nonhydrostatic Weather and Climate Model (ICON) global 160km resolution soil type data, as developed by the Deutscher Wetterdienst (DWD) and the Max-Planck-Institut für Meteorologie (MPI-M). The data targets the mesh faces/cells.

Note that Natural Earth coastlines are also rendered.
