Terrestrial Groundwater Dependent Ecosystem (GDE) Density

This dataset is based on the Potential Terrestrial Groundwater Dependent Ecosystem (GDE) mapping undertaken by Dresel et al. (2010). Dresel et al. (2010) recognised that the dataset over estimated the occurrence of mapped terrestrial GDEs. For this reason, the GDE dataset was refined to provide information regarding the relative density of GDEs across the State. Areas of very low GDE density were assigned less weighting than an areas with very high GDE density GDE. This provided a suitable solution to the problem of mapped GDE over estimation.

本数据集基于Dresel等人（2010）开展的潜在陆地地下水依赖型生态系统（Groundwater Dependent Ecosystem, GDE）制图工作。Dresel等人（2010）指出，该数据集高估了已制图的陆地GDE的分布情况。因此，研究人员对GDE数据集进行了优化，以提供全州范围内GDE相对密度的相关信息。对于GDE密度极低的区域，其权重赋值低于GDE密度极高的区域。这为已制图GDE的高估问题提供了一种合适的解决方案。
