Design and implementation of an expert interface system for integration of photogrammetric and Geographic Information Systems for intelligent preparation and structuring of spatial data

摘要

Preparation of spatial data for Geographic Information System (GIS) simultaneously during feature digitizing process from photogrammetric models reduces data editing phases after feature digitizing process. Therefore, the problems, caused by separating spatial data production process from preparation of this data, are overcome as far as possible. To achieve this purpose, specialty and expertise required for spatial data structuring and preparation for GIS, should be available in an interface system which establishes a direct connection between photogrammetric and GIS systems. In this case, when a user digitizes a feature from a photogrammetric model, decision making process about the method of editing, structuring, layering, and storing of the feature in GIS database, can be carried out by such an interface system. Thus, according to the capabilities of expert systems for modeling the knowledge and deduction methods of experts, generating an expert interface system between photogrammetric and GIS systems, offers a suitable solution for this integration. In this paper, the capabilities of expert systems for intelligent spatial data structuring and preparation simultaneously during feature digitizing process from photogrammetric models, have been investigated. Also, design, implementation and test of an expert interface system for integration of photogrammetric and GIS systems in order to take advantages of capabilities of both systems simultaneously as one integrated system, has been described.
