Apple Maps gives the wrong location for several apps

I’m out the field daily birding and photographing wildlife. I use my iPhone 14 Pro to check the “Weather”, use the birding app “Merlin” and “iNaturalist” and occasionally post photo to “Facebook” while still on the move. One area I cover almost daily is a CT State Park in Madison, CT. All of the above mentioned apps report I’m in “West Haven, CT.” This is nowhere near Madison, CT. When reporting a sighting I have to manually note that the location is incorrect. This has been happening since I purchased the phone over a year ago and I hope iOS upgrades would eventually fix the location issue. Here at iOS 18.0 and “Location Services” still is not reporting the correct location.
