Buffer areas for nearest neighbours or national marine areas delineation

A few weeks ago, Christina Buelow asked on Twitter how she could create the polygons of coastal waters using the land polygons, and making sure there is no overlap in buffer areas. This would make it possible to know which land area is closest to any place in the sea. Let’s explore what solution …

Spatial interpolation on Earth as a 3D sphere

Earth map is usually presented flat. Geographical coordinates usually go from -180° to +180°. Spatial interpolations using coordinates may be tricky as -180° is equal to +180°. Here I propose a way to realize spatial interpolations on Earth as a sphere and then map the outputs in 3D using rgl. The …
