Using cognitive information in the expert interface system for intelligent structuring and quality control of spatial data measured from photogrammetric or remotely sensed images

Abstract

Preparation of spatial data for GIS simultaneously during feature measurement process from photogrammetric models reduces data editing phases after feature digitizing process. Therefore, most of the problems caused by separating data production process from preparation of the data are overcome. To achieve this purpose, specialty required for spatial data structuring and preparation, should be available in an interface system which establishes a direct connection between photogrammetric and GIS systems. Design and implementation of the first version of the expert interface system for integration of photogrammetric and GIS systems show that expert system capabilities for modeling the knowledge and inference method of experts, has an effective role in automation of spatial data preparation and structuring. In this paper, capabilities of expert systems for spatial data preparation and structuring are explained and main structure of the first version of the expert interface system is presented. Implementation and test of a new designed section to provide required information for identifying active features and improve decision making capability of the expert system are also discussed.
