Dear list,

I would like to have the z-values of a river shapefile in R (sp). So that I have at the end a list of x,y and z-coordinates, for which I do further analysis.
Is there a way of importing a 3d-shapefile direct in R?
When I was using the readOGR command,  the following message appear.
****************
riv_CH <- readOGR(".", "riverz")
OGR data source with driver: ESRI Shapefile
Source: ".", layer: "riverz"
with 13 features and 13 fields
Feature type: wkbLineString with 3 dimensions
Warnmeldung:
In readOGR(".", "riverz") : Z-dimension discarded
*****************

Do you have any suggestion for handling the z-dimension?

Thanks a lot in advance, Rosi
