My understanding of the location reporting of the Shake is that it is obfuscated for privacy and Branden mentioned that in a future release there will be logging of GPS location. Where and when is the data obfuscated i.e. does the Shake send accurate GPS location data to ShakeNet and it is then obfuscated before being made public or is it obfuscated in the RPi before transmission?
If you are planning to log GPS data to /opt/logs would the plan be to log accurate GPS data or the obfuscated location?
I am experimenting with interferometry techniques to image subsurface structure from correlated data acquired from two or more Shakes. The timing and accurate location of the devices is an important part of the process. Of course I can do this with with a handheld GPS, but it’s more manual data handling, more scope for human error, etc. and my units have a GPS built in anyway.
It would be nice if we had some control over how this obfuscation occurs, i.e. is the GPS location shifted by a fixed offset, is it a randomised offset, or can we disable it altogether?
I hope I haven’t created more questions than answers here.
