Internationally validated open access indicators of large public urban green space for healthy and sustainable cities - supplementary materials

Full description

This data package contains supplementary materials related to large public urban green space (LPUGS) availability and accessibility indicator validation conducted for 13 diverse cities worldwide. This research was initiated by the Global Observatory of Healthy and Sustainable Cities for the 1000 Cities Challenge and inclusion in the Global Healthy & Sustainable City Indicators (GHSCI) open-source software.

This data package contains the following:

1. The Jupyter Notebook hosting a custom Python script that makes use of the Google Earth Engine API to apply Normalized Difference Vegetation Index (NDVI) filtering on areas of public open space derived from the GHSCI open-source software to identify LPUGS.
2. A folder for each of the 13 cities involved in the study, containing spatial data in .shp format for the urban centre boundary, large public urban green spaces, accessibility grid, and pedestrian network. Additionally, official local reference data is included for the 4 select cities analysed.
3. The instructional video provided to collaborators is also included as a .mp4 file, which outlines how to access the accessibility web map, how to perform the LACO-Wiki validation, and how to access and record comments in the live spreadsheet.
4. The complete validation spreadsheet with comments included as a .pdf file.
5. Supplementary tables listing the urban centre boundary source files, official local reference data details, and further characteristic details of the 13 cities analysed as a .pdf file.
