Hi,
There are hard constraints for geometries to be valid in JTS (I think
point < 2, linestring > 1, polygon > 3),
but empty geometries are considered as valid for every type. There WKT
version are
POINT EMPTY
LINESTRING EMPTY
POLYGON EMPTY
...
A weird consequence is that POLYGON EMPTY != LINEST

Open zip with Open wizard. OJ gives tons of messages about failing open some
image formats.
Tested with r3883-Plus.

sorry, right.. i seem to remember geometrical objects to be tightly regulated
in JTS, e.g. points are not allowed to be les or more than 1 point. funny
enough i can create a POINT EMPTY manually. weird.

Have you tried? Create a feature with WKT
GEOMETRYCOLLECTION EMPTY
For me the geometryconverter says that only points can be converted into
"Point". The desired result, I believe, would be
POINT EMPTY.

Hi,
JML is not an option because no other software reads it and I cannot send data
back to Oracle. A locally installed PostGIS could work but I will need to test
how it behaves with empty geometries.

Hi,
Yes I can but I do not want to. The features are real and have
valuable attributes, they are just missing the geometries because they
have not been digitized yet. I read them from Oracle with DB Query
Plugin but I must save them to a temporary format because I can't save
them back to Or
