1700 addresses for USA-based government ArcGIS servers

Anyone looking for government GIS data is welcome to use the list of ArcGIS server addresses that I curate. The list is focused on ‘root’ addresses for USA-based government ArcGIS servers. The list currently has 1,700+ server addresses from the federal level down to the city level. These are individual server addresses, not layer addresses.

Note that the list is mainly focused on ArcGIS servers, not portals. Anyone that has additional addresses for USA-based government ArcGIS servers is invited to send those addresses my way so they can be included on the list. I am looking for root addresses ending in "rest/services". Here is my contact page: https://mappingsupport.com/p2/gissurfer-about-contact.html

Any link that goes bad is promptly fixed or removed from the list. Each link on the list is automatically scanned once per week by my own code. I review the report produced by that scan and make any needed tweaks to the list. I expect that most weeks there will be an updated list posted mid-week with at least some changes.

A text file can also be downloaded by changing the file extension to txt. So far I have not produced a csv or json file. I might at some point but there is lots of higher priority work to do first.
