Google Earth Anomaly
On 3/2 I placed my GPS track on GE. Then on 3/9 I drove the same route and placed my GPS track on GE and there is a huge disagreement.
I used reinstalled GE and my converter program and did it over and got the same result. Then I used the track from Inreach and still got the same
result. So two independent GPS's agree.
I have been doing the same process of placing my GPS tracks on GE for over 20 years and have never had this issue. My track always agrees with GE even
at max zoom.
If you examine the GE image, you can see that the 3/9 route highway 3 is shifted just like my track.
If you examine my Inreach Image from Garmin you can see it exactly shows the track correctly for the 3/9 trip.
My conclusion is the issue is not the GPS track but is something with GE?
Can anyone tell what happened?

what time stamp (month/year) is on the respective images?
in my experience, a track recorded in 2006 will match GE images of 2006 - but not 2021
a 2021 track recorded will only match 2021 GE images
white track - 2006 recorded
black rack -2022 recorded
2006 GE image
2021 GE image

GE photos are not precise, photo data may differ from gps data you collect.
Make sure all your data and photos are in same gps reference datum.
The visual separation you show in lines seems normal for remote areas.
Woke!
Hands off!

I know it is not the same thing, but I was driving a beach road south of Punta Conejo, and my automotive GPS showed me trolling just offshore. I
didn't know my Kia could swim!
If you are not living on the edge, you are taking up too much space!

You must have goat's brand of GPS that thinks the sea level is a lot higher!

Datums verified. GPSs are the same as GE, WGS 1984
Yes, Many times repeated runs show a slight shift. That only shows up at large zoom levels as shown above. Nothing similar to my images where even the
background shifted for the latest run.
Google does suggest a different computer setting causing a shift.
I suspected a new setting for my computer, so I did the same process on a different computer with all new downloads and installs and got the same
result.

Problem identified. My file was way to large. Braking the track file into two parts solves my issue.
The reason my files are so large is because I use a lot of waypoints, and my track point interval is 3 seconds on my Lowrance and 5 seconds on my
inReach Explorer.
