Pentax O-GPS1 unit for K-5
As far as software goes, I think it is a feature of particular websites to "trawl" through a photo's additional data to determine if a standardised geo-positionary "signal" is encoded into the image.
I have found that Flickr will "geo-position" photos I take on my gps-enabled smartphone, but in the absence of a gps device in my Kr, I have to geo-position my photos manually.
I'm not even sure if this was the answer to your original question, but hopefully it is of some use.

I would hope that pentax software could read the data from a pentax product though.
k5, 50mm FA, 18-55mm Kit, 50-200mm DA, 15mm Fisheye Sigma, 10-17mm DA Fisheye, 18-55mm DA WR, DA* 60-250, DA* 16-50
Does anyone out there know if it's possible to link GPS data from the O-GPS1 to photos in Pentax Digital Camera Utility 4? I can't find any info on the Pentax website. If I can't use DCU4, what software should I use to map GPS locations to photos and Google Maps or similar?
Many thanks

Lightroom. works a treat.
I Borrowed Miss Smeggy's mobile phone ( blackberry ) after installing a GPS logging app on it. I put in the car dashboard and drove around with my cam on it's drive by shooting mount and fired off loads of pics as a test.
Got home loaded the geolog file into lightroom and voila it automatically drew the route in google maps in it's map module and tagged the all selected pics.
I had to syncronise the time between teh camera and the mobile phone, which wasn'teasy given the Blackberry doesn't have a seconds readout. but I could easily shit the EXIF data of the series of pics back forth by a second or two to match the locations ( 2 seconds is quite a distance whiel driving.

Most of the go tags were within a metre accuracy. then just hit control-S and the GPS lcoation is written to the iamge file. Or is exported during a lightroom export caommand.
