As my apparent obsession with GPS continues, I have created this Google Earth SD Card Logger for you all to play with. This will create GPS logs that are directly usable in Google earth with no additional processing. I have copied a test log KML file for those without SD card hardware and an image from Google Earth as well.
You will notice that the 3D plot sometimes disappears below the ground image. This is because of the accuracy of GPS altitude. Is it often 'off' by more than a meter. Since I was riding a bike around the block to collect data, an error of -1m could easily put the line underground. To see all data in GE, right click DATALOG at the left menu at the bottom, and select PROPERTIES, then play with the altitude settings.
*** UPDATE - the .kml file is in the ZIP. the forums software won't let me post .kmls directly. ***
