It would be great to mention this in the relevant chapter: https://github.com/walkerke/crsuggest

Specifically it would fit perfectly here: https://geocompr.robinlovelace.net/reproj-geo-data.html#which-crs-to-use

Heads-up @walkerke, awesome package, let me know if you've any comments/suggestions on describing the package and thanks for developing it!

Now that we are using general rotation representations, we need utility functions to convert conventions in software such as Datamine and Leapfrog to Euler angles. These are two possible definitions:

DatamineAngles(θs...) = EulerAngles((-1 .* deg2rad.(θs))..., :ZXZ)

LeapfrogAngles(θs...) = EulerAngles((-1 .* deg2rad.(θs))..., :ZXZ)

We need a similar definition for `GslibAng

In some ways fasterize does diverge from rasterize (e.g., #13). These should be tersely described in the README/vignette and function documentation.

mf_background() adds background images underneath maps:

library(mapsf)
#> Le chargement a nécessité le package : sf
#> Linking to GEOS 3.7.1, GDAL 3.1.2, PROJ 7.1.0
mtq <- mf_get_mtq()
th <- mf_theme("default", bg = "grey20", fg = "grey80")
mf_init(mtq, theme = th)
mf_background(system.file("img/background.jpg", package = "mapsf"))
mf_map(mtq, lwd = 2, col = NA, border = "grey80",
