New release 1.1.0 allow computations on the sphere. Some worldwide grids (levels 1 to 11) have been precomputed using dggridR and can be found here.
Once downloaded, read a grid geopackage using st_read from sf package such as:
grid <- sf::st_read("grid06.gpkg")

Want to discover MAPI usefulness? Enjoy our showroom (in progress):
- 3D visualization of two carab species genetic distances over landscape (CORINE landcover, 2000): C. punctatoauratus and C. nemoralis.
Zoom and rotate the images in order to explore links between landcover and genetic distances.
Another view for C. punctatoauratus where the relief is infact the genetic similarity (the higher, the more similar) with a superimposed OpenStreetMap layer.
Enable or disable layers from top-right menu. Thanks to "Qgis2threejs" QGis plugin!
- Animation illustrating genetic links during a simulation of invasion process along a river.
