shapefile polygon opens in arcgis but n ot mapserver

[Brenningmeyer, Todd M.]

Hi,

I've had to deal with a similar issue connected with shapes with M values (I
can't recall if they also had Z).  When I had the entire polygon within the
view it was visible but if any portion of that file extended outside of the
viewer the rest of the features for that shapefile would disappear.  I was
able to get around this by removing the z and m values and exporting a plain
2D shapefile.  After that everything worked.  The issue appears to be the
way mapserver opens or handles M and possibly Z shapes.  The shapes were
created with arcgis 9.0 which may be part of the problem as ArcGIS products
tend to handle and create shapefiles a little differently than arcview 3.x.

Hi,

It should work if you are using Mapserver 4.4 or later.

Otherwise try showing it through OGR.

CONNECTIONTYPE OGR
CONNECTION "path/my.shp"

Best regards,
Bart
