This makes me wonder how much effort I want to keep putting into keeping it running.
I don't know why I didn't notice this until just now, when wks commented on the thread.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
My own version is much cleaner however 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.
