QuantySurvey

Overview

The QuantySurvey computer-aided geological survey system is the outcome of a key high-tech development project (9506002) of the former Ministry of Geology and Mineral Resources under the Ninth Five-Year Plan. In the field it runs a data collection subsystem on ultra-light portable computers (Tablet PCs); in the office it runs a compilation and mapping subsystem on desktop computers, with powerful modules for integrated compilation, statistical analysis, spatial analysis, regional assessment, geological map compilation and report writing. With it, all attribute, spatial and image data for traverses and geological observation points can be collected conveniently in the field, and mapping can be done by directly revising land resource and geological sketch maps. The whole process, from field data collection to office compilation and map drafting, becomes computer-aided, skipping the manual drafting stage to achieve "paperless mapping". The product was granted a national invention patent in 2003.

The system also integrates field survey, geophysical, geochemical and drilling records, enabling cross-retrieval, integrated processing and integrated application of "multi-S" information. Storage, retrieval and processing of spatial and attribute data become automated, fast, networked, integrated and intelligent, laying a solid foundation for 3D geological mapping. Because it uses the industry's unified data model, standard coding system, standard map symbols and legends, agreed processing methods and common software interfaces, the system is highly specialized. Competent authorities (provincial bureaux and ministries) can use it together with network technology to build complete "basic geological information systems" and "land and resources information systems", effectively advancing the "Digital Land" programme and laying a solid foundation for digitizing geological survey work and making land and resources information available to society.
