The establishment of a multipurpose cadastre based on digital orthophoto techniques


With the advance in computer technology during the last decade digital
photogrammetry has become operational and is gaining more and more acceptability.
Especially the ability to display geo- and height-refernced digital orthophotos on the
monitor of digital workstations has given us a very powerful tool for multipurpose mapping. Screen-digitization offer a practically unlimited scope for data aquisition, as the full content of the aerial photograph is available for interpretation and mapping. The applicability of the digital orthophoto is demonstrated on some executed projects.
