Abstract:
Surveying (spatial recording) and GIS definitely accompany the entire process of acquisition of both thematic as well as geometrical data throughout the whole duration of SFB HiMAT.
The use of aerial and close-range photogrammetry, 3D-scanning (airborne and close-range laser-scanning), mapping and graphical representation (visualization in plans, maps and 3D models) of identified historical structures, mines, buildings, archaeological sites and archaeological finds is essential for documentation, archiving, publication and understanding of complex interactions and correlations between disciplines. As these different measurement techniques deliver data in different resolutions and accuracy, adequate and successful data fusion of these heterogeneous data into an identical framework of coordinates is still a challenging task.
Recording of thematic data of all groups is complemented by spatial registration (e.g. by using GPS receivers) to deliver data that can be stored and further used in any spatial context. Geoinformationsystems (GIS) have been established to acquire, archive, administrate, analyse and represent these spatial data. A graphical user interface (GUI) allows the access to the entire database with spatial concern (coordinates). Vice versa, the thus established databases can – in combination with geo-basis-data - be requested to represent these data in charts, maps and plans of its thematic content. Different subprojects / user groups so use of the graphical geobasis data for different questions, change and edit their own data and connect and correlate it with the result of others. Thus the establishment of a powerful Geoinformationsystems for the entire project was necessary from the beginning / planning of the project to guarantee that from the start onwards all available data can be used by all project partners simultaneously.
The above GIS databases have also been connected to historical maps and plans after having them referenced to the same coordinate frame as the other data already stored (geocoded). So a combined representation of all available (even recent topographical) data - within old maps - will be possible and e.g. has the potential to compute and visualize the historical changes in surface geometry the volume of waste-heap, erosion etc.
