Groundwater alluvial boundaries - polygons - Queensland

A compilation of Groundwater Alluvium Boundaries containing polygons describing Alluvium Boundaries within Queensland. The data was obtained from departmental maps showing bores, borelines and alluvium boundaries. Some data was captured from geological maps showing alluvium. The scale and detail of these maps was varied and diverse with some maps not providing a full coverage of an area.本数据集为地下水冲积层边界（Groundwater Alluvium Boundaries）汇编成果，包含用于描述昆士兰州境内冲积层边界的多边形要素（polygons）。该数据源自标注有钻孔、钻孔剖面线与冲积层边界的部门官方地图，部分数据提取自标注冲积层信息的地质图件。上述地图的比例尺与细节丰度参差不齐，部分地图未能实现对应区域的完整覆盖。
