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.
