Explain it to me like I am five…

Every time I think I have figured out what Google Street View expects, I encounter a new problem. This time, I have a file that Google says has gaps in the GPS data:

But the problem is, I have already tried to fix this multiple times using tools like gpsbabel. This command line utility will create in-between points at the rate you specify. You can use a value of 1 second and get a point every second in the entire GPX file.

Using GPX Editor on the Mac lets me inspect the tracking points. If I sort by duration value, the longest value in the entire file is 4 seconds:

Yet, Google claims there is a 7 second gap after 9 seconds. Looking at the points in time order shows this is not the case: (But do note, this GPS starts sooner than the video; so the points I show here may be from time before the video begins. This does not change the issue, since there is nothing reported longer than 4 seconds in the entire file, anywhere.)

Anyone care to explain why this happens and how I can fix it? I have gotten every other file I have uploaded to work just fine, except for these two I have been working on since last week.

Even when I run gpsbabel with a 1 second “gap” between each point, I still get this type of error.

What else is Google looking for? Web searches and even chatting with Google’s Gemini A.I. have not produced anything helpful.

Comments appreciated…
