The impact of data quality filtering of opportunistic citizen science data on species distribution model performance: dataset used for Maxent modelling.

This dataset contains all the necessary data to repeat the analyses conducted in the article 'The impact of data quality filtering of opportunistic citizen science data on species distribution model performance'. Per square kilometer in Flanders, the csv-file contains (i) the model predictor values, (ii) the filtered and unfiltered presence-only occurrences of the 255 considered species used for model training and (iii) the presences and absences per species used for model testing. Details on how the data was collected and how the dataset was formed can be found in the article's Methods and Materials and Supplementary Information.

本数据集包含了复现论文《机会主义式公民科学数据的质量过滤对物种分布模型性能的影响》（The impact of data quality filtering of opportunistic citizen science data on species distribution model performance）中所开展各项分析所需的全部数据。在法兰德斯（Flanders）地区的每平方公里尺度下，该csv文件包含三类内容：(i) 模型预测变量值；(ii) 用于模型训练的255个研究物种的过滤后与未过滤的仅存在型观测记录；(iii) 用于模型测试的各物种的存在与缺失记录。关于该数据集的采集方式与构建细节，可查阅该论文的《材料与方法》（Methods and Materials）及补充信息（Supplementary Information）章节。
