Geoscientifical data model and research of data fusion technology
Dai Ta · Journal of Central South University of Technology(Natural Science) · 2001
This paper discussed the building of geoscientifical data model after generally describing the basic concepts, main data sources and general characteristics of geoscientifical data. Geoscientifical data models have two types of modes: vector and raster. Vector is made up of point, line and polygon. Based on the characteristic of geoscientifical data model, the application of data fusion and the general method used in geoscientifical data are discussed. Data fusion is mainly expressed by fusion of information of supplement and cooperation, fusion under entropy′s structure, fussion of multi source of remote sense. The method of data fussion in geoscience is made up of imagine interpreter, expert system, geo statistics and multi statistics, manual NN. It is a new attempt in geoscience, and will be a new issue for the application in geoscience of data fussion.
