Hi Martin

Feel free to use our free datasets at http://www.sogis.ch/daten You just have to register to download, but the data are all free to use.
You may use e.g the Cadastral survey data of the City of Solothurn. In the zip you'll find Bo_BoFlaeche_A (ground cover, Polygon), Li_Grenzpunkt (border points of the properties, points). For lines there's e.g. Ei_Linienelement (line elements of the ground cover) or Bo_BoFlaeche_B (the same as Bo_BoFlaeche_A but not polygonized).
