Geo Photos (GPS plus Camera = Geolocation photographs)
Sunday, January 21st, 2007UPDATE: Found a nice self contained unit that replaces the Pocket PC, and Bluetooth gps receiver, more information at the bottom of the post.
I have been wanting to set this up for some time and recently found a combination of hardware and software that work for me. What is this all about you ask? Well let me shed some light on this. Geo photo, coding, or what ever you want to call it, is the ability to write GPS data to jpeg EXIF headers. This text data is stored in the header of a jpeg adding the longitude, latitude and altitude you took your photo at.
You can do this a few ways, first of all you can buy a camera with built in gps (as of this time they are still pretty low quality), buy a hand held gps device that stores (waypoint, GPX, NMEA data) or a combination of devices. I have chosen the latter because I had a few piece of hardware already. Most if not all devices export out to some data format the one I choose is NMEA data since it works with the software im using on my PC.
My hardware setup consists of:
- Pocket PC with built in bluetooth
- Canon SD900 10 mega pixel camera
- i-Blue 737 bluetooth gps.
and the software im using:
So how do you make this all work?
Well in theory you connect your gps to your pocket pc via bluetooth launch the Navio software, start it’s gps logging option which can record every few seconds your location to a file and then take your photos.
