Liu Gang, Wu Chonglong, Wang Xinqing. RESEARCH PROGRESS OF FIELD WORKING SYSTEM OF COMPUTER-AIDED REGIONAL GEOLOGICAL SURVEY[J]. Advances in Earth Science, 2003, 18(1): 77-084.

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.
