Open Route Service

Mon, 01/25/2010 - 22:34 — mdeweerd

I discovered an 'open' service that I did not know about yet: Open Route Service.   The site demonstrates the route calculation between two positions on the map.  I did not test it a lot, but I will likely look into it later.

If you test it more before I do, do not hesitate to leave a comment.


Skytraq Log Format support and Conversion to GPX, KML, KMZ, ... .

I got a CanMore GT-730F(L) GPS Dongle with Data Logger to have a hands on evaluation of a device with a Skytraq Venus624 GPS inside.  I was pretty surprised to find that it did not have a battery allowing it to log positions without USB power.  The performance on my desk is not exceptionnal compared to the iBlue 747 A+, but for the moment I blame the design for it - not the chip.
