[Qgis-user] Android phone GPS to QGIS or BeeGIS

[conradh]

Hi Zoltan,

Have you tried using Franson GPS gate. I used it a couple of years back to
interface between a "Qstarz" GPS data logger which transmistted a NMEA live
stream via blue tooth and QGIS on a laptop. I came to the conclusion that
sometimes the QGIS buffer gets full so using GPS gate buffers the live NMEA
stream and generlly keeps things orderly.

I am not a fan of using your phone GPS for the following reasons a) battery
life b) you always need to use your phone for something else and c) if you
use a stand alone gps transmitter you can tape it to the front dash in the
car/ put it under the sun visor etc so that you have a clear gps signal
through the front windscreen of the car. The application was ground truthing
power line routes around Ankor Watt in Cambodia to ensure the line routes
were outside the nominated temple areas and worked quite well. However the
learnings were that it is hard to use a laptop in a car on a bumpy road and
you should always have a backup gps logger.  I also taped a mobile phone USB
dongle to the front windscreen of the car so I could download GE as a
background map in real time but this did not work so well, too many wires
and not a good phone signal in some areas. If I was doing it again I would
have the case of a GPS transponder taped to the front dash so I could easily
remove the transponder as needed (they get hot in the sun when parked) and
use some sort of tablet, with good battery life, which would be easier to
use in a moving vehicle. In a similar manner if you are data logging while
wandering about you can put the transponder in your hat band as they are
quite small and you will be more likely to recieve a good gps signal (clear
view of the sky)
