Children’s walking to urban services: an analysis of pedestrian access to social infrastructures and its relationship with land use

The data and codes that support the findings of this study.<br>The dataset includes pedestrian path network and public social infrastructures in Seoul. All data are in shapefiles importable to GIS software.<br>Code descriptions are below.<br><br>Through two scripts, we can create walksheds from all linestring features in a pedestrian path layer.
