Testing GlobalSat DG100

Posted by dolphinpix on 28 January 2008 in English.

Uploaded, 2008 England Peak district - test run of GlobalSat DG100.

Car has a hardwired (powered from the car stereo 12V - so it comes on when the car is running) GPS data logger based on the DGPS-XM4 Model GPS DataLogger ( http://homepages.tig.com.au/~robk/ ) fed from a Garmin Serial WAAS mouse embedded under the plastic trim of the dash, out of sight.

Another DGPS-XM4 attached to a handheld garmin marine GPS again with WAAS for walking, however enabling serial NMEA output cuts down the GPS battery life to 8 hours (not good for long walks or camping).

Answer, replace the DGPS-XM4 and serial cable with something smaller, lighter with its own batteries. So a test of the GlobalSat DG100. First results look good!

GPX Sensible file sizes

Posted by dolphinpix on 24 January 2008 in English.

Okay, discovered files which were good for Geotagging photographs are too long to OSM in terms of fair share of processing time.

Now cutting track logs down to below < 5000 points where possible.

Projects,

Highlands of Scotland - 10 years of GPS track logs, but only plan to upload tracks under 5 years old as well aware of new road layouts in certain areas of the highlands.

Derbyshire/Staffordshire Peak District, uploading extensive data covering white peak.

Lake district, less popular areas, uploading data covering western and northern areas.

Royal Deeside, minor roads.
