Design and implementation of an expert interpreter system for intelligent acquisition of spatial data from aerial or remotely sensed images

The significance of the imaging as a source for extracting spatial data is an important issue in today's world such that a huge part of the data required by spatial data management organizations is provided through imaging. Because of the increasing number of aerial and satellite sensors and the need for data processing in different applications, the necessity of having automated tools for the interpretation and analysis of digital images is clearly obvious. Due to the need for a human operator, the manual interpretation is a time consuming and expensive task. Use of computer tools and an intelligent system for the automation of the image interpretation process saves time and project cost, and also reduces human errors. In this paper, image interpretation is described, and a review is given on different interpretation systems. The capabilities of the expert systems are investigated considering the requirements of the interpretation systems. Finally, an initial interpretation system based on expert systems is implemented and tested.
