Well, in MapInfo (also commercial GIS) you can have different geometry types in the same table. Oracle Spatial supports not only multible geometry types in same table, but even multible geometry columns for each feature. Perhaps more flexibility is better, but of course software should help the user in avoiding doing things he really don't want to do. -Jukka Rahkonen- _______________________________________________ jump-users mailing list [email protected] http://lists.refractions.net/mailman/listinfo/jump-users
