Base information for a local scale Species Distribution Model of Baccharis halimifolia and Juncus maritimus in the Oyambre estuary, Spain

The data includes the presences and pseudoabsences used for building a Species Distribution Model for the species Baccharis halimifolia and Juncus maritimus, at local scale in the Oyambre estuary, in the northern coast of Spain. It also includes the environmental rasters used for the models, both a dataset with the training conditions in 2005 and the evaluation conditions in 2014.

The rasters include statistic values of hydrodynamic variables, salinity and other information used to build the models at a resolution of approaximately 10x10 m.

The presences are spatial points indicating the location of known occurrences of the species in the years 2005 and 2014 in the estuary. The pseudo-absences are points generated randomly with a 20 m buffer around the presences. Readme file inside the folder with more information.

本数据集包含用于构建物种分布模型所需的数据，包括在西班牙北部海岸Oyambre河口的Baccharis halimifolia和Juncus maritimus物种的实地尺度下的存在和伪缺失信息。此外，数据集还包括用于模型构建的环境栅格数据，涵盖了2005年的训练条件和2014年的评估条件。栅格数据包含了水文动力变量、盐度及其他用于构建模型的信息，分辨率为约10x10米。存在数据由表示已知物种发生位置的时空点构成，而伪缺失数据则是在存在点周围20米范围内随机生成的点。文件夹内的Readme文件提供了更详细的信息。
