[Gdal-dev] problem with polygonz shapefile and ArcExplorer ...

[LALLAURET Fabrice - <SSII>]

Hi,
I have a problem with the shapefile driver in the 1.3.2 release of OGR. 
The shapefiles seems good with ArcMap or ogrinfo but can't be display 
with ArcExplorer 9.1 (Linux & windows)
(the console of ArcExplorer display the following message : > Nov 29, 
2006 6:28:41 PM:    com.esri.mo.file.shp.db 
com.esri.mo.file.shp.InvalidShapeException: 1 invalid shape/s were 
detected in ...)
I've tried with ogr 1.3.1 and it works.
The problem seems to be the addition of the "bMeasureIsUsed" in the 
shpopen.c file. When I force it to TRUE, the generated shapefile can be 
succefully display in ArcExplorer.
Why this flag act on SHPT_POLYGONZ type ?

I have attached to create a small shapefile which I can't display on 
ArcExplorer

Regards
