[fdo-users] Spatial Filter Help Needed

[Gavin Cramer]

FDO property names are case-sensitive.  For SHP, they are usually taken from field names, which are often uppercase by conventoin.  Perhaps it is supposed to be SHAPE?

I'm trying to intersect a circle (created from input coordinates) with a
shapefile.  I've created the circle geometry and am now trying to set up the
filter.  In the code below, the statement

while(reader.ReadNext())

throws the follwing exception:
"The property 'Shape' is not in the readers selected property set"

SUGGESTIONS....THANKS

**********************************************

OSGeo.FDO.Expression.GeometryValue pGVal = new GeometryValue(pByteCircle);
OSGeo.FDO.Expression.ComputedIdentifier pPropName = new
ComputedIdentifier("Shape", new Identifier("Geometry"));

IdentifierCollection pIDColl = sel.PropertyNames;
pIDColl.Add(pPropName);

OSGeo.FDO.Filter.Filter pPtLineFilter = new
OSGeo.FDO.Filter.SpatialCondition(pPropName,
OSGeo.FDO.Filter.SpatialOperations.SpatialOperations_Intersect, pGVal); }

OSGeo.FDO.Commands.Feature.IFeatureReader reader = sel.Execute();
while (reader.ReadNext())
{
     ......some code....
}
