基于MapObjects野外地质数据采集系统设计与实现

野外地质数据采集系统是计算机辅助区域地质调查系统的一个重要组成部分,由于没有合适的数据采集的地质模型和数学模型,使常规十分简单的地质现象用计算机辅助进行数据采集、存贮、处理显得十分困难.文章通过以点为核心的数据采集模型,利用数据库前端与后端分离技术、动态模型技术、元数据、数据字典技术、数据分块存储、共享技术,在Visual Basic 6.0与MapObjects相结合的环境下,研发了地质数据采集系统,有效的把老三件(地质锤、罗盘、放大镜)与新三件(笔记本、GPS、数码相机)有机的结合起来,实现了地质数据的方便采集、存贮、处理及输出.

DESIGNING AND REALIZATION OF FIELD GEOLOGICAL DATA COLLECTION SYSTEM BASED ON MAPOBJECTS

The field geological data collection system plays an important role in the computer-aided regional geological survey system. However, owing to no proper geological model and data model for data collection, there are many problems in using computer to describe the phenomena of geology, which is very simply with the old way, for example the data collection, storing and data processing. This paper sets the point as the core of data model, and makes good use of dividing the database into fore-part and back-part technology, automatic model technology, metadata technology, data dictionary technology, and the data storing which is separated to story. Using Visual Basic 6.0 and MapObjects, data collecting, storing, processing and importing have been realized, combining the three old tools (geology hammer, compass and amplifying lens) and the new tools (computer, GPS and digital (camera).)
