Hi, GIS it to large extent based on principle "one geometry - one set of attributes". The bird observation case would handle easily a situation where each observation has an own point geometry. Your case is rather often handled in two steps: user clicks on a polygon, application gets an ID for the area and sends a query to the database, reads the observations and shows them for the user. I know that BirdLife of Finland has been building some bird observation stuff on top of QGIS and WFS. Maybe you can try to find some contact there. -Jukka Rahkonen- _______________________________________________ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user
