Regional E-Atlas of the Greater Phoenix Region: Areas of significant agricultural and residential groundwater use, 1996-2000

Spatial distribution of well water usage (groundwater) for the period 1996 - 2000. These data present significant areas of agricultural and residential groundwater use during this period. This is a spatial data object with a Coordinate Reference System (CRS) of EPSG:3479 NAD83(NSRS2007) / Arizona Central (ft); https://www.spatialreference.org/ref/epsg/3479/). The coordinate reference system (CRS) associated with these data when they were constructed initially was misrepresented in early versions (<= knb-lter-cap.101.8) of this dataset. The CAP LTER has attempted to assign a CRS based on reasonable values but the accuracy of the identified CRS cannot be certain.

1996—2000年期间井用水（地下水）的空间分布情况。本数据集呈现了该时段内农业与生活用水地下水使用的显著分布区域。该数据集为空间数据对象，其坐标参考系统（Coordinate Reference System, CRS）为EPSG:3479 NAD83(NSRS2007) / Arizona Central（英尺）；相关详情可查阅https://www.spatialreference.org/ref/epsg/3479/。该数据集在初始构建阶段所关联的坐标参考系统，在其早期版本（<= knb-lter-cap.101.8）中存在错误标注。CAP LTER已尝试基于合理参数为其分配坐标参考系统，但所确定的坐标参考系统的准确性仍无法保证。
