Design and Realization of Column System Based on MAPGIS
Wei Lian · Earth Science-Journal of China University of Geosciences · 2006
The content of the column system is related to spatial positions. This paper presents a column system built on a GIS base to clearly show spatial relationships between the strata. According to the content and the representation of the graph, the column describes the geological entities by means of spatial data format, such as dots, lines and areas. The data organization of the system is accomplished by object-oriented methods. System functions are realized based on MAPGIS. System builds different traces to present the data, which has different attributes and operations. It has a friendly interface and provides templates to build the column. The system accomplishes a column by multiple descriptions of the strata.
