摘要：Detailed data captures from past decades are available in some cases for very famous historical objects of cultural heritage. So a complete set of historical plans exists for the world famous Castle of Heidelberg (about 700 plans acquired 1883-1889) which offers a high quality in large scales (1:40, 1:5 and 1:1). The presented paper demonstrates that this precious historical data base is very useful for current conservation as well as for new construction activities inside the castle. To be able to integrate this great amount of analog plans into modern data processing and management systems the original plans had been digitized by means of a scanner. Afterwards the ground plans were geometrically rectified on the base of control points which could be still identified. The measures of the actual status were done by tacheometry. The obtained accuracy after transformation lies between ± 1cm and ± 3cm which seems to be suitable for the required tasks mentioned above. To convert the information of the scanned and rectified ground plans from raster to vector format the graphical elements had been digitized manually. In the same way all sheer plans (upright projections) of vertical walls had been geometrically rectified, however, they were not manually digitized (due to the extensive amount of work) but overlaid with currently created orthophotos of these objects. The accuracy was slightly lower (between ± 1cm and ± 5cm), dependent on the number and spatial distribution of the still identifiable control points
