Area-weighted mean greenspace patch size
Variable Definition
Weighted average of urban patch size (in hectares). This value is weighted by the area of each patch. Greenspace patches and total area are net of water bodies and exclude limited no observation areas in remote sensing images (due to cloud and shadow). This variable is calculated for L1UX using a 2017 greenspace map at 10 m resolution. Due to the large size of L1AD and L2, this variable is calculated using the same greenspace map resampled to 30 m resolution. Interpretation: Indicator of fragmentation. Larger values reflect a larger size of greenness; low values reflect scattered, small greenness. By weighting by patch size, larger urban patches have a higher influence in this weighted-average metric. Researchers could decide at their own discretion on using this weighted index or the corresponding unweighted one.
