In general, as a “casual” gis user, I find very useful in this package the “raster as a matrix” concept, it facilitates a lot the raster treatment, but I find complicated to pass from the (xid,yid) space to the coordinates space and vice versa (see also [my other post](https://discourse.julialang.org/t/how-to-get-value-and-matrix-index-at-a-given-x-y-point/129692/9)). Perhaps an API that facilitates these passages would be useful…
