hoogw

Now I know 3 city:

By use /data.json, I can get all dataset for that city.

City of Raleigh

https://data-ral.opendata.arcgis.com/data.json

city of los angeles

https://geohub.lacity.org/data.json

Spokane County WA
https://data-ral.opendata.arcgis.com/data.json

I want more city, I want a full list of all city sub-domain

If I have that full list, I can use below URL to get any cities any dataset.

https://{city-subdomain}.opendata.arcgis.com/data.json

Ok, socrata open data have a full list of domain (233 city county state, etc...)

Here is working sample:

https://transparentgov.net/cleargov1/410/socrata-list-230-organization

In theory, ESRI should (if they have NOT yet) create a FULL list of sub-domain just like what socrata open data did.

Why? you see, any city, county are sub-domain of {city-sub-domain}.opendata.arcgis.com

or hub.arcgis.com/{city-sub-domain}::{layer-name-id}

both url-format above are inter-changeable

I have collect over 1000+ arcgis server list here,

https://transparentgov.net/cleargov1/418/arcgis-list-1000-organization

https://transparentgov.net/cleargov1/764/arcgis-1000-organization

Now I have collect 60+ of {city-sub-domain}.opendata.arcgis.com geohub.arcgis.com/xyz
hub.arcgis.com/xyz

ESRI should maintain this full list, but they have not done yet, I end up do myself to create such list.
