Does anyone have a suggestion for a map provider I can use with Leaflet that provides country outlines only? The closest thing I can find so far is one of the Carto "No Labels" maps, however, even those show some additional features at certain zoom levels.

NOAA has GIS layers  that just display country outlines. 

Here is a GISsurfer Leaflet map I produced that uses dynamic layers to restyle that data.

Hello,

My site only use country outlines. If you want to do something like it, I can send you the JSON file.  note: I removed a couple of tiny countries in the oceans because they end up just looking specks on the map.

I’d love to see a map that outlines the counties, but only those showing on the map already.

Did you mean counties or countries?  I have the JSON for the countries that are on my site:  oneworld-futbol.com

The map link I posted has a bunch of GIS overlay layers you can turn on/off.  One layer displays country outlines.  Another layer displays USA county outlines.  The overlay layer that is 'on top' can be clicked to display all the attribute data for the thing that you clicked.  For help using the map, click "Map tips" upper left corner.

Years ago I had a project where we made world boundaries for ever year from WW2 on with a accompanying data sheet. I need to find a use for it. Michael Page, geographer

I meant COUNTIES within each state of the United States. I would like one that I can only show for the area on the screen.

The national map (from the USGS) has an ArcGIS layer that displays county outlines
See layer 23 at:

Is that what you are looking for?

Here is a Leaflet map centered on your county and using the default styling defined on the server to display that layer.

Since this layer supports 'dynamic layers', your map can restyle the data.  For example:

These are Exactly what I’m looking for. Thanks Joseph.

Great - glad I could help.  BTW, that map service has a different layer that you can use to add county names to your map.

If you might be interested here is a version of the map I want to add it to. But there are very literally hundreds of others which is why I want the counties only for what’s on the screen.

I took a quick look at your map and code.  I expect you realize there are newer versions of both Leaflet and the ESRI plugin.  And at the risk of adding to your work, I  suggest you add some support  for USNG/MGRS coordinates.  FEMA is working on shifting to that coordinate system for large scale disaster response.  You could start with a simple coordinate conversion tool and later on work on adding grid lines.
Actually there are some ArcGIS overlays I could dig out that will add USNG/MGRS grid lines.  Lemme know if that would be useful.

Actually I wrote that code so long ago I didn’t know about the new versions. Getting these maps working was far more work than almost all the rest of the code I wrote for Net Control Manager. The only grid system in use right now is the Maidenhead Grid Square system used by ham radio operators, which is who the overall application is used by.
But I do want to look at the new version of Leaflet and ESRI I wish I could predict what that would do to the existing code. Being a one man band here, retired, two grand children, and three other kids taking up my time it may be a while before I can modify all the MySQL, PHP, etc. for it.

I really appreciate your time to look at my stuff, if you ever run out of things to work on Joseph, please let me know. In the mean time thanks again.

Hi Harry,

This thread has gotten so long I don’t see any map links by you, The only ones I found in the thread are way to complex for this old head to get around. Maybe you could repost your link and I’ll give that a try.
Thanks...
