|
| Abstract:The database for groundwater resource in China constitutes a part of the research achievements of the project "New Round Nationwide Groundwater Resource Assessment" sponsored by the Ministry of Land and Resources. Covering the spatial and attribute information of groundwater resource and environment, it has realized the transition from the paper media to the digitalized information flow so as to represent the achievements in a better way, and has also laid a foundation for realizing the data sharing to a wider extent. This paper deals with the designing thought and the construction process of the groundwater resource database in such aspects as its overall structure, standardization of groundwater resource information, map layer division, data gathering, technical flowing process and quality control system. |
