Modeling image interpretation in remote sensing through a virtual GIS shell (VGIS)

摘要

Abstract: Automatic capturing and updating of spatial data by means of remote sensing and image processing, nowadays, poses one of the major problems in the efficient use of geographic information systems (GIS). The paper describes a project that aims at the use of the `knowledge base' inherent in GIS for automatic interpretation of remote sensing images. The implementation and proficient use of GIS have become so complicated, that it is growing towards a domain in itself. As a first step of a subsequent integration, we propose the development of a `virtual GIS shell' (VGIS). It frees image analysts (as well as other GIS- Inexperienced users) from learning the internals of GIS to use this technology for their purposes. VGIS is a first step towards an automatic use of the immense knowledge and data incorporated in a GIS. VGIS allows users to deal with abstracted data, hiding technical information about the database and allowing them to concentrate on the users' tasks. !19
