计算机辅助区域地质调查野外工作系统研究进展

RESEARCH PROGRESS OF FIELD WORKING SYSTEM OF COMPUTER-AIDED REGIONAL GEOLOGICAL SURVEY

计算机辅助区域地质调查系统是近几年来在我国迅速发展的高新技术系统。其中野外工作系统是整个系统研究的瓶颈和关键之一,有针对性地综合探讨了国内外相关野外工作系统的发展现状和特点,并就其工作模式进行了对比研究,总结了系统研究开发的体系结构、途径和发展方向。国内外的实践证明,数字化填图系统的应用将显著提高传统区调工作的效率和精度,对于我国新一轮国土资源大调查和"数字国土"工程的建设有重要意义。

Computeraided regional geological survey system is a high and new technology system which was developed rapidly in China in recent years. In the whole system field working system is the key research part. In this paper, development status and characteristic of related field working system of different countries were discussed, and their working models were also compared. The field working system of Australia's FieldPad, Canada's FieldLog, United States' GeoMapper, Switzerland's FieldBook and China's GeoSurvey were introduced. Besides the software, the hardwares used in field system are also important because of field hard working environment. Some new hardwares were also described in this paper, such as Laser Binoculars with Digital Compass and Under Sunlight Readable Color Screen, et al. Based on the review, the system structure and research approach was pointed out. Methods of multiS integration and information system is essential to the system development. According to great progress in computer technology, new trend is the field working system based on lightsmall laptop computers. Lots of system application practice show that digital mapping system will improve evidently the efficiency and precision of traditional regional geological survey works. This computeraided system is very important to the Chinese new round national land and resources survey and 'Digital Territory' engineering.
