10hz GPS for data collecting for openstreetmap
I'm looking at picking up another GPS unit to use for gps tracking in order to give something back to the Open Street Map system.
But I was thinking that a 5hz, or even a 10hz GPS would be better for data logging, as a lot of my driving would be at 60km/h or faster.
There are a couple of options, either this one:
Which comes in at US$60, or getting one of these:
For AUD$67, although that would require soldering a USB serial adapter onto it, and possibly playing round with software and drivers to get it to run properly.
The main question is, would a 10hz unit give better datalogging? I am assuming it would be able to handle twists and bends in the road slightly smoother than a 1hz or 5hz unit.....
Your thoughts people? I'm happy to spend that kind of money, and I can then update the unit in the car to this one once I have the datalogging figured (I currently just use an iGPS-m Pro 1hz USB GPS, so the update to something faster would be good for me with GMPC). I could even integrate the datalogger into the carpc, although for now I would just sit the laptop on the passenger seat while I'm out for a drive, and leave the carpc for my regular music/nav duties.
