I’ve noticed recently that a lot of the GPS traces in my area are doing weird things. Many of the traces are fine, but a good portion of them are what can only be described as ‘dashed’. I thought it might not be just mine, so I checked other areas of the world, and it’s happening other places too.

Here’s a sample from my region. Most of those traces are my own, but some are dashed and others are smooth. I think that the dashed ones are more recent.

What’s also perplexing is that I can download the trace from OSM, and it displays all the detail that there should be.

Does anyone know what’s going on?

EDIT: I looked back over my traces, and everything back to about July 26 is fine, but prior to that for a couple months is all funky.
