This paper evaluates advantages of application of digital photogrammetry for the purposes of production of technical documentation for the objects under protection, comparing it with the classical photogrammetric procedures. Based on gained experiences, paper reviews procedures for the completely digital production of technical documentation. Process of making technical documentation is divided in two logical stages. First stage comprises of photogrammetric recording, necessary field measurements and production of archive documentation. Archive documentation is in completely digital form and it includes: geometrically rectified photogrammetric photos, data on control points, parameters of exterior orientation for all photos and digital orthophotos as a preliminary source of geometric information. Second stage involves the production of detailed documentation with data describing object geometry such as: floor plans, facades, sections, etc, by using suitable CAD tools. Considering that this constitutes the most complicated and the most expensive part of making technical documentation, this stage is done when needed. Proposed method will be illustrated in paper by using experiences gained on projects of making technical documentations for objects of historical and cultural heritage for the towns of Kragujevac (Serbia and Montenegro) and Banja Luka (Republic of Srpska). |
