Abstract
A coherent geographical information system Geo-union has been implemented on microcomputers and put into practical use with many Remote Sensing projects. In this paper, major functions and characteristics of the system are presented, and a typical application system for environmental study of dynamical analysis and planning of geo-resources is discussed in terms of using Geo-union as a basis of application tool-set.
Introduction
The geographical information system (GIS) in conjunction with remote sensing study has become increasingly important. On the basis of GIS, result data from remote sensing study not only can be stored and queried, but also be further processed and analysed by using dynamical analysis and planning models. These are the major goals of our efforts to develop a geo information system GEO-UNION which has been implemented on microcomputers and been put into practical use with many remote sensing projects. In following sections main characteristics of the system GEO-UNION, and its major functions will be presented. A typical application of environmental study on dynamical analysis and planning in terms of geo-resources management will be shown to exemplify the capacity of the system that it can further be used as an software development tool-set for professional application development users
