This page describes the cleaning process for JSON and GeoJSON data used in spatial analysis across different scales.
The cleaning module Python script can be found here (Cleaning - Spatial Data).
This data is used in appendix fashion, and as GeoJSON data, it's not easily accessed or used as dataframes, and therefore initial or final snippets. However, the process will be described.
The final results can be seen by use in the mapping functions here. Additionally, the outlines of the main areas are displayed below.
