Data underlying the publication: The relation between proximity to and characteristics of green spaces to physical activity and health: A multi-dimensional sensitivity analysis in four European cities

The research objective was to examine if the significant findings between green space, physical activity and health stem from unique green space characteristics or similar mechanisms. This dataset is a correlation matrix of 105 green space indicators gathered in GIS, covering 7 different green space characteristics (surrounding greenness (NDVI 0-1), accessible greenness (NDVI 0-1), accessible green space (m2), accessible green corridors (m2), accessible total green space (m2), sum of green space uses (n), mix of green space uses(n)) in 15 distances from 100 to 1,500 m every 100 m.

本研究旨在探究绿地、身体活动与健康之间的显著关联，究竟源于绿地的独特属性，还是相似的作用机制。本数据集为基于地理信息系统（GIS）采集得到的105项绿地指标相关矩阵，涵盖7类不同的绿地特征，具体包括：周边绿地覆盖度（归一化植被指数（NDVI），取值范围0~1）、可及性绿地覆盖度（归一化植被指数（NDVI），取值范围0~1）、可及绿地面积（单位：平方米）、可及绿色廊道面积（单位：平方米）、可及总绿地面积（单位：平方米）、绿地使用类型总数量（单位：个）、绿地使用类型混合度（单位：个）；所有指标均以100米为步长，在100米至1500米的15种距离梯度下完成采集。
