My personal opinion is that the interpretation of the coordinate dimensions should not be directly mixed into getting the number of coordinate dimensions. But I could be wrong headed on this. I second Frank's your opinion here.

Re: [geos-devel] getCoordinateDimension() - ticket 311
getDimension follows the OGC spec. Seems to me it's better to simply change it to match the spec and the C++ API. This was clearly a bug in the first place, no? strk wrote: On Tue, May 25, 2010 at 09:27:16PM -0400, Frank Warmerdam wrote: I think we will have to change the values returned by the C API getDimension function to match C++ even though this introduces a modest risk of problems for applications using the undocumented current behavior.

Re: [geos-devel] getCoordinateDimension() - ticket 311
I have to disagree. Mathematically speaking the topological dimension
is a counting number (e.g. in the set {0,1,2,...}. I don't see any
reason why this shouldn't be represented as an integer value (and plenty
of reasons why it should - e.g. ordering, comparison, etc)

My enum suggestion was for the spatial dimension, not coordinate dimension.
PUNTUAL/LINEAL/AREAL kind of enum.
