GPS data logger (skiing, trackdays etc)

[glade]

Last year i tried to buy a Navman ski tool off ebay but when it arrived it didn't work.

Today I found this...

Ski-log for £99. (demo video here)

Which appears to be this GPS datalogger on ebay with a different logo.The ski-log product also appears to have a UI designed specifically for skiing and easy interface with google earth.

I went a bit mad last night and bought the ebay datalogger.

I have already found some aviation websites and a gps visualiser that can create tracks in google earth, but software suited to skiing/trackdays would be better.

Anyone got any experience with GPS datalogging?

Any good software I could use with it?

I just use my 2610 or eTrex as a logger more than anything else. The Garmin software interfaces with Google Earth. I am not certain you can overlay logs on normal Earth without subscribing, unless the logger comes with software. Having said that progs like GPSBabel can often convert logs into formats that might. I can overlay on Arquet mapping, Memory Map and G Earth but there is sometimes a bit of jiggery pokery. What format does in log in?

Don't know what format, but i definately need to find out... I assume it will just give a CSV file.

I've found a site that does FREE software for track analysis. Looks pretty good in their marketing bumph. Question is if i can import the data from this datalogger.

Default: GGA, GSA, GSV, RMC; Optional: VTG, GLL need to look and see what will handle those I suppose. Or does it export in other formats?

i wasn't sure if that was an output from the gps sensor, not the data logger?

Do GPSW do this one? If so look at the specs on there I would before I buy on ebay. In fact they may do loggers for not much more.

I got the GPS datalogger last week... seems pretty good. certainly gets an accurate track.

Here is a track of me driving accross town. Its bang on all of the roads in google earth.
Track accross town

Using excel i can chart height and speed etc. Everything that the £100 ski software does really.

I'm pretty pleased that I have saved a bit of cash and that I can get the unit to do what I want... the unit is even sensitive enough to work inside my factory... Time and motion studies might get interesting

Do these devices and software compensate for height as well as distance? If it doesn't factor in height changes they can't be very accurate.

For example, if you skied 1.4 linear miles down a 45 degree slope, as the crow flies that would only appear to be 1 mile, giving you a lower speed reading.

it logs height above sea level, so I assume so.

Might seem like a silly question. But why on earth would you want to log your skiing? Can't you look at a piste guide?
