Digital Images in Support of Historical Building Data Bases
The study of complex monuments is highly interdisciplinary, requiring input from surveyors, architects, archaeologists, historians, geotechnical and structural engineers, etc.
A specialised Data Base is required in order to organise and preserve all of this information. In particular, rectification and orthoprojection techniques allow for geometrically corrected raster images to be inserted into a Data Base; particular software applications are required to preserve this characteristic.
This paper presents the results collected during the study of an extremely complex monument, both in terms of single photograph treatment as well as mosaicking of multiple images. Particular attention was given to defining specific criteria which could be applied for the manual creation of a Digital Elevation Model (DEM), which is necessary for the orthoprojection of a monument image.
