资源简介:

The dataset is a feature class showing the boundaries of 515 groundwater basins and subbasins as defined by the California Department of Water Resources as last modified by the Basin Boundary Emergency Regulation adopted on October 21, 2015 and subsequent modifications requested through the Basin Boundary Modification Request Process. The file is in ESRI geodatabase format and is intended for use with compatible GIS software. Groundwater basins are represented as polygon features and designated on the basis of geological and hydrological conditions - usually the occurrence of alluvial or unconsolidated deposits. When practical, large basins are also subdivided by political boundaries, as in the Central Valley. Basins are named and numbered per the convention of the Department of Water Resources. The associated data are considered DWR enterprise GIS data, which meet all appropriate requirements of the DWR GIS Spatial Data Standards. DWR makes no warranties or guarantees, either expressed or implied, as to the completeness, accuracy or correctness of the data, nor accepts or assumes any liability arising from or for any incorrect, incomplete or misleading subject data. The official DWR GIS Data Steward for this dataset is Brett Wyckoff, who may be contacted at 916-902-6779, or at brett.wyckoff@water.ca.gov. Comments, problems, improvements, updates, or suggestions should be forwarded to the official GIS Data Steward as available and appropriate.

本数据集为要素类,包含515个地下水流域及子流域的边界信息,该边界由加利福尼亚州水资源部(California Department of Water Resources,简称DWR)划定,最新版本经2015年10月21日通过的《流域边界紧急条例》以及后续通过流域边界修改申请流程提出的修改方案更新。 该文件采用ESRI地理数据库(ESRI geodatabase)格式,适用于兼容的地理信息系统(GIS)软件。地下水流域以多边形要素形式呈现,其划定依据地质与水文条件——通常以冲积层或松散沉积物的分布为依据。若条件允许,大型流域还会按行政边界进行细分,例如中央谷地。流域的命名与编号遵循DWR的规范。 本关联数据属于DWR企业级GIS数据,符合该部门地理信息系统空间数据标准的全部相关要求。DWR不对本数据的完整性、准确性或正确性作出任何明示或默示的担保,亦不承担因使用本数据(包括数据存在错误、不完整或误导性内容)而产生的任何责任。 本数据集的官方DWR GIS数据管理员为布雷特·威科夫(Brett Wyckoff),可通过电话916-902-6779或邮箱brett.wyckoff@water.ca.gov与其取得联系。如有评论、问题、改进建议、更新需求或其他相关提议,请联系官方GIS数据管理员。
