摘要
对勘探精度及分辨率要求越来越高的地球物理勘探方法对测量技术提出了更严格的标准,而"3S"(GPS、RS、GIS)技术在物探测量中的应用,为物探测量工作带来更好的解决方案。通过分析"3S"技术在测量中存在的若干技术和概念问题,指出GPS技术在物探测量中的应用,可有效提高测量精度,保证测量数据的可靠性,提高测量效率,降低工程费用;RS技术在物探测量中的应用,为在沼泽地、高山区等不易到达的地区施测提供了参照资料,其小于1m的影像图分辨率,对于物探施工设计、变观放样及精确绘制测线草图,提供了较大方便;基于位置多属性处理和分析的GIS技术,在数据处理、图形处理、空间查询、可视化表达等方面,为提高物探测量技术水平提供了强有力的技术支持。
Corresponding to more and more requirements on geophysical prospecting precision and resolution, stricter standards of surveying technology, resulted along with. While the application of ＂3S＂ （GPS, RS and GIS） technology in geophysical prospecting surveying bring forward a better resolvent. Analyzed several technical and conceptive issues in ＂3S＂ technology in surveying, pointed out the application of the GPS technology in geophysical prospecting surveying can improve survey precision effectively, ensure data reliability, increase efficiency and reduce cost of surveying; while the application of RS technology can provide reference data for swamp, high mountain areas where not easy to reach, its 〉1m image resolution is facilitated to geophysical prospecting design, flexible setting out and survey line exact sketch mapping; the GIS technology based on position multi-attribute processing and analyzing can provide vigorous support on aspects of data processing, graphic processing, spatial query, and visual expression, thus to improve geophysical prospecting surveying technical level.
