Advanced Techniques for the Management of Geological Mapping
Abstract from thesisThe transfer of information from a 1:25.000 geological database to the printing of a 1:50,000 geological map sheet is a major problem in geological map production. It relates mainly to the greater detail of field information archived in the database with respect to that needed at a smaller representation scale. This research is focused on a new implementation of a geological database scheme that allows a digital version of the rules to be used by geologists and cartographers in the generalization process. Additionally, a system to avoid overcrowding of symbols is prototyped.
A review of the major works on multi-scale databases and on the concepts of categories and hierarchies has influenced the generalization model proposed for multi-representation. Geographic Information Systems provide the means to carry out the necessary operations. The proposed system is based on the application of conventional and artificial intelligence computer techniques for the production of digital geological cartography, from the gathering of geological field data to the printing of a geological map. Four parts comprise the system:
