The KML files have a "red fence" where the height is based on speed showing your journey.
They are split every N minutes (the default is 5) but all will load into Google Earth where the time slider will work.
Is the kml2kmz just a gzip?

Internally they contain the raw GPS data (so if you want actual altitude, etc. you can post-process - also the light and temperature from the tablet).
Still, the kml/kmz logging from minigpsd seems to be working OK for me now, so thanks very much for the help tz1. Nice work.

> Is the kml2kmz just a gzip?
This is just a wrapper around gzip that changes gzip headers to (pk)zip headers and the central directory which is what kmz files are. Most GPS data compresses over 10:1.
>Would be nice to get Google Earth to replay the KMZs in flight sim mode.
It will bounce every 5 minute kml - there is a "lookat". I didn't want to clutter it up too much and it can be post-processed.
I did a 5 minute split to minimize problems when there might be bad data (found a problem with minus signs inside XML comments, occasional system crash, etc.). Also so you can more easily discard dead data or find the point you want.
(losing 1 hour of log is worse than 5 minutes, and searching thousands of lines for a bad marker is much easier than searching millions of lines).

tz1,
Has Google suspended your API key for maps? I get a key error..
also, this is in the dogmap.html source:
Google has disabled usage of the Maps API for this application. See the Terms of Service for more information:
several pages back someone requested using their own key in a config file.. This would prevent your key from being suspended..

The source is available.
The key is in the source.
I've not had problems.
