Problem with 3D shapes with the mapserver shape driver

[tamas]

Currently mapserver cannot display the 3D shapes properly when the built-in shape driver is used even if USE_POINT_Z_M is enabled during the compilation.

More information:

msSHPReadBounds in mapshape.c is not aware of the 3D point features, and these features are treated as non point features so the returning rect is invalid.

For fixing the issue in ln 1293

if (psSHP->nShapeType != SHP_POINT) {

should be replaced with

if (psSHP->nShapeType != SHP_POINT && psSHP->nShapeType != SHP_POINTZ) {

We should probably add similar checks for SHP_POINTM as well.

Changed to C library (or is it really just affecting utilities?) and 5.0.1 release since this seems like a serious bug.

I'll leave this bug to Steve, but call on me if needed.

Anybody got test Z and M shapefiles laying around that they could post here?

3D (XYZ) Line file (breaklines).

I made the changes suggested by Tamas in the 5.0 branch and the trunk. I'd be obliged if someone could confirm that this works for them.

I tried with both line (which I believe worked in the past) and point shapefiles and all was ok. Closing...
