County and city ArcGIS server addresses are included in this report with the hope that students in middle school and high school will use those local resources to help them learn about and explore geospatial data for their own backyard. As explained below, most of these server addresses were found with simple Google searches. This report is online as follows: pdf file https://mappingsupport.com/p/surf_gis/list-federal-state-county- city-GIS-servers.pdf txt file https://mappingsupport.com/p/surf_gis/list-federal-state-county-city-GIS-servers.t xt csv file https://mappingsupport.com/p/surf_gis/list-federal-state-county-city-GIS-servers.c sv All three file types are updated once per week. The csv file only includes GIS server addresses at the state and county level. The FIPS code is included in the csv file. @ArcGIS server administrators: Thank you to those who have converted from http to https. However, too many of you have not yet made this conversion. Do you know that SSL certificates from https://letsencrypt.org/ cost nothing? And there is a second group of you that has attempted to convert to https but either have not done so correctly or are using SSL certificates that the browsers do not trust or that have expired. Those servers are flagged in this report as having an SSL problem. If you would please get new SSL certificates from LetsEncrypt, then this problem will go away. To test your https implementation, try browsing to your “rest/services” address and see if an error message appears. Both Chrome and Firefox browsers require TLS 1.2 protocol. Way too many of you are still using TLS 1.1. Why am I doing this? I am a software developer in the field of online maps. One of my projects is GISsurfer which is a general purpose web map based on the free open-source Leaflet map API (Application Program Interface). One of the features of GISsurfer is the ability to display *any* public-facing (i.e. no login required) ArcGIS MapServer, ImageServer and FeatureServer data. If you would like to give this a try: 1. Open GISsurfer: https://mappingsupport.com/p2/gissurfer.php 2. Zoom in on a state, county or city where you would like to see some GIS data. 3. Click the basemap button and change the basemap to “USA basemap”. 4. Click the basemap button again and look under the “Overlay” heading (mobile users might need to scroll down). Select “Add GIS overlays”. 5. Use this ArcGIS server list to copy the address for an ArcGIS server for that state, county or city and then paste that address into the GISsurfer dialog box. 6. Click “Send request to GIS server”. After a few seconds, the sidebar will open and display the top of the table of contents for that GIS server. 7. Click an entry in the table of contents to go down to the next level. 8. An entry with a checkbox can be displayed on the map as an overlay. Click that entry to add that GIS data to the map as an overlay. 9. Click “Menu” ==> “Link to this map”. The link that is displayed will replicate the map on your screen. For more information please visit the GISsurfer homepage. Click the green “Menu” button and then select “Help”. Scroll down just a bit and start by reading the “Overview” section. Automated weekly scan: Once a week my code automatically tests each link in this report. Each link is tested at least 3 times spread over a 24 hour period. Bad links will promptly be fixed or flagged. Addresses in this report that are flagged “dead link” are not clickable. No doubt in many cases that government entity still has an ArcGIS server but has simply changed the address and/or configured their server for internal use only. Every few months I will check the jurisdictions that are flagged “dead link”. In many cases I will be able to find a new ArcGIS server address to add to this list. If you find out any new ArcGIS server addresses, please let me know. 2 Each GIS server link will also be tested to detect (1) if directory services (i.e. table of contents) has been disabled and (2) whether login credentials are required. This automated weekly code will also test each http link to see if there is now a https version. This report will be updated with any such new information. Usually an updated list will be posted each Wednesday morning. Tip: Sometimes a link that is flagged as ‘dead’ is only down temporarily. If you think such a link might have data you would like to see, you can always replace the leading underline character with the letter “h” and give the link a try. Tip: If you are looking for a certain type of data, try a Google advanced search. For example, if you are looking for trail data then search on: trails site:___________ Replace the underline with the address for an ArcGIS server and enter that search into a browser bar. See any mistakes? Some of the servers in this list have multiple jurisdictions and from one entry to the next they jump between states/counties/cities. No doubt I became mesmerized a time or two by the repetition involved and entered some server addresses under the wrong state. Or I may have entered a city server’s address in the section for county servers or vice versa. I cannot fix it unless someone tells me I goofed. Why are the multiple entries for some counties/cities? The focus of this list is to present links that go directly to data for a state agency or county or city/town/village. Some of the servers on this list have data for multiple jurisdictions. It would have been nice if the server administrator had made a folder for each jurisdiction and then put all the data for that jurisdiction into that folder. Unfortunately, sometimes that did not happen. Data ‘Portals’: Yes, this report does include some addresses for federal and state data portals. No, publishing portal addresses is not the primary purpose of this report. Want to help #1? If you know of a federal, state, regional, county or city ArcGIS server that is not already listed below and that includes at least some data where no login credentials are required, please send me an email via the contact link posted above. Note that I am only looking for the ‘top’ endpoint for ArcGIS servers. Those links all end in “rest/services”. I would particularly like to get addresses for more ArcGIS servers operated by regional planning bodies. Want to help #2? Each state has a section for links to county ArcGIS servers and then a section for links to city ArcGIS servers. Find your state and see if it looks like I listed any city servers in the county section or vice versa. Want to help #3? Some counties and cities have agreed to cooperate and have data layers for both jurisdictions on a single server. When that happens I want to show both the city name and county name in this list along with a pointer to whichever one is hosting the combined data. If you know of any such ArcGIS servers, please send me an email via my contact page. Go to https://mappingsupport.com, click the big green “Menu” button and select “About and contact”. 3 Want to help #4? See the section “USA Miscellaneous Servers” near the start of the list. If you can identify any of those links as primarily having data for one state or one county or one city, please let me know and I will move that server link to the appropriate location. Caution: Some of the GIS data on these servers will be draft and/or temporary. Also the server administrators sometimes renumber the data layers with little to no warning. This will break any maps that are based on the former layer numbers. Another common problem is the use of gibberish names to identify data folders/layers/attributes combined with the lack of metadata to translate that gibberish into something useful. And when you want to ask a question about the data usually the GIS server metadata lacks any contact information. Anyone can easily search for ArcGIS servers. Assume you want to know if St. Louis County Minnesota (County seat is Duluth) has a public-facing ArcGIS server. First, find the county website. Note that the website address includes “stlouiscountymn”. Second, do a Google search on: stlouiscountymn “rest/services”.
