I need a geojson for the official boundaries of the nairobi metropolitan area. likewise, the wards and subcounties in laikipia county as per the humdata dataset are outdated. newer documents indicate 5 subcounties instead of 3. the 2 extra subcounties are laikipia central and nyahururu subcounties. anyone with data please get in touch ASAP
For problems like that one, i use one site - osm2cdr.com
there you can choose any region or regions you want, make their style the way you want and export in any format you want. geojson is also there.
you can search for the source that you believe on modern metropolitan borders, and download a geojson with all that subregions together.
