数字地质调查信息综合平台(DGSS)在我国地质调查中逐渐占据主导地位。以1∶5万水系沉积物化探测量后期成图的实际应用为例,通过迭代法计算背景值和标准偏差,求得异常下限,进而绘制出地球化学元素等值线图及异常图;通过软件集成的数据分析功能分析各元素相关系数,确定元素组合,绘制组合异常图、综合异常图。展示数字地质调查信息综合平台在处理数据及数据成图两方面所具有的功能强大、方便快捷、高效精准的优点。
Digital Geological Survey Information Integration Platform (DGSS) in China’s geological survey gradually occupy a dominant position. Taking the practical application of late mapping of the sediment geochemical exploration of 1: 50000 series water as an example, the iterative method was used to calculate the background and standard deviation, and the lower limit of anomaly was obtained. Then the contour map and abnormal map of geochemical elements were drawn. The integrated data analysis function analyzes the correlation coefficient of each element, determines the element combination, draws the combination anomaly chart, and synthesizes the anomaly chart. Show digital geological survey information integrated platform in the processing of data and data into two aspects of the powerful, convenient, efficient and accurate advantages.
