This makes me wonder how much effort I want to keep putting into keeping it running.

Ben, I think NJGIN has been really fast and stable ever since they made some changes last year. I wouldn't give up on them yet, this was evidently just a little glitch. They are getting ready to make a bunch of service changes again on August 23, so maybe this is related? As I read it, the changes should have no effect on the maps we use though. https://njgin.state.nj.us/oit/gis/NJ_NJGINExplorer/docs/NJOGIS_Service_Deprecation_notice.pdf

What is FML? I recently spent a little time starting to put together my own USGS topo for the Northeast US, but it's a huge project and I got discouraged. If you just want New Jersey, NJGIN has that. We discussed this a few years ago, and IIRC your objections were that NJGIN's servers were slow and they don't switch to the 100k topo when you zoom out.

I think NJGIN servers work very well now. And there should be a way to combine their 100k and 24k WMS layers to accomplish what you want. In Leaflet it's very simple to create a layer group and configure the zoom levels for each map. Isn't this possible in the Google API? If not, then this open source package should be able to do it: https://mapproxy.org

If all else fails, I can put a tileset together for South Jersey that you can host locally at NJPB.

I'm not much of a fan of the arcGIS topo, there are a lot of JPEG artifacts and it isn't even a "real" USGS topo, it's the old National Geographic version with hillshading that muddies things up and adds nothing in flat areas like the pines. The NJGIN version is a little odd because they converted the maps to a 12-color palette in an attempt to standardize the colors. I don't think they're too bad though, you can compare here

NJGIN: https://online.boydsmaps.com/#15/39.8187/-74.5357/njgin24k
arcGIS: https://maps.njpinebarrens.com/#lat=39.81865&lng=-74.53568000000001&z=15&type=topo&gpx=

My own version is much cleaner however :D https://online.boydsmaps.com/#15/39.8187/-74.5357/pines1999

Mine also goes up to level 16 while both NJGIN and arcGIS are only level 15. But it's probably a bigger tileset than you would want to host at NJPB. I could give you a level 15 version however, that would be around 1GB for South Jersey.

I don't know why I didn't notice this until just now, when wks commented on the thread.

The extra level is nice to have but I occasionally use the topo map for things outside of NJ, which the NJGIN and Boydsmaps versions wouldn't cover (as far as I know.)

A Pennsylvania USGS 24k Topo is available on the mobile app.

https://mobile.boydsmaps.com/#15.00/40.792350/-77.842326/pa24k/0.00/0.00

Am also making a regional Mid-Atlantic 24k topo, which is a big project that will take awhile, but it's coming. :)
