山东省莱芜市幅1∶50 000水文地质图数据集

This dataset is prepared based on the latest data obtained from a new round of hydrogeological survey with the 1:50 000 Spatial Database of Topographical Map and some data of 1:50 000 Geological Map of Laiwu City, Shandong Province, as the base map. In addition to the hydrogeological map, the dataset includes data sheets on pumping (domestic) wells, springs, boreholes, water quality analysis and calculation of water volume including 209 pumping (domestic) wells, 14 springs, 13 reservoirs, 13 long-run monitoring points (936 point-times monitoring data), 100 point-times of simultaneous-measurement of groundwater level and groundwater volume, 6 environmental geological points, and 90 sets of samples acquired (total analysis, isotope and rock). For this dataset, the platform MapGIS 6.7 is used to prepare maps, the data size is about 169 MB, and the national geodetic coordinate system CGCS 2000 and Gauss-Kruger Projection (6-degree belt) are adopted. Furthermore, not only is 2D method used to mark critical hydrogeological information in the dataset, 3D method is introduced in the master map and part mosaic maps to express relief.本数据集以山东省莱芜市1:50000地形空间数据库及部分1:50000地质图数据作为底图，基于新一轮水文地质调查获取的最新数据编制而成。除水文地质图外，本数据集还涵盖抽水井（民用）、泉点、钻孔、水质分析及水量计算相关数据表，具体包含209眼民用抽水井、14处泉点、13座水库、13个长期监测点（配套936测点次监测数据）、100测点次的地下水位与水量同步监测数据、6处环境地质点，以及90组采集样品（含全分析、同位素及岩类分析）。本数据集采用MapGIS 6.7平台进行制图，数据体量约169 MB，采用2000国家大地坐标系（CGCS 2000）及高斯-克吕格6度分带投影。此外，本数据集不仅通过二维方式标注关键水文地质信息，还在主图及部分镶嵌图中引入三维方法以表达地形起伏。
