Hi all, I am looking to extend the SpatialPoints and SpatialPointsDataFrame classes to include altitude information. Somebody recommended I check in with this group for pointers before getting too far along on this.
It's possible for Points in sp, but not for polygons or lines. library(sp) x <- matrix(rnorm(27), ncol = 3) SpatialPoints(x) But, the general support outside this in sp is very limited once you break out of the plane.
Thanks Mike! I had no idea that coordinates() handled three-dimensional matrices already. In that case, it looks like I don't have to do anything at all (for now).
I'm working on tools to make this much easier, and to translate from sp to other forms and back.
I look forward to seeing what comes out of this! -Eamon
