Hello, this is where the analysis behind CITYACCESSMAP lives. CITYACCESSMAP is a web application for global scale urban accessibility insights. Please explore the app here for more information.
To download the processed data for any city that the application covers, please go here (each file is a different urban area, and is named according to the Urban Centers Database's naming convention). To reproduce the data collection and analysis behind this data please go here. Global-scale raw amenities data is collected from OpenStreetMap using OsmPoisPbf and the uac_filter.txt query. Accessibility calculation are computed using the 1_calculateAccess.py script. Population grids for functional urban areas are extracted from the Global Human Settlement Layer and pre-processed using the 2_extractUA_QGIS.py script, to be run in QGIS. Accessibility per grid cell (the data used for the visuals in the app) for urban areas globally is computed using the 3_calculatedGridAccess.py script.
The scientific research behind this project is published here.
