OBJECT STYLES OF SPATIAL ENTITY FOR FIELD GEOLOGICAL MAPPING BASED ON OBJECT-ORIENTED METHOD
Abstract：In order to carry out field geological mapping and data acquiringwith computer assisted technology, the focus should be put on the acquiring of field geological spatial entity data, so as to develop geological mapping field data acquiring system. With the help of software engineering and system engineering, the combination of object-oriented software developing technology with practical field mapping is applied in every stage of the system development. Methods for the analysis of the field mapping spatial entity and the analysis models for its data object are studied. In this paper, the building of E-C-R model of field geological spatial entity, class hierarchy and information structure model are discussed. These models have been the base of this system development and satisfactory effect has been achieved.
