It’s been a few weeks since I first mentioned my Canon GP-E2 GPS receiver, so it seems like as good a time as any for an update. I’ve taken it out for a few walks in and around Newcastle, and I’ve got a few observations.
Every GPS thingy I’ve used takes a while to lock on to the satellites in the vicinity of Grey Street – I presume it’s the proximity of lots of buildings that causes that. The GP-E2 takes a similar amount of time, so don’t expect to be able to switch on and have an accurate location fix immediately. It only takes a minute or so, but it’s worth bearing in mind. I suspect it’ll lock on quicker in more open locations.
Location accuracy in central Newcastle and Gateshead is generally at least as good as I’ve seen with other devices – within a small number of metres for the most part, with some variations which I’d attribute to local conditions, such as large masses of metal and concrete in the vicinity of the Pilgrim Street roundabout. Certainly good enough for knowing where your pictures were taken. One point that I read somewhere was that we don’t actually know how accurate the geographical coordinates are on the Google maps that are used by both Canon’s Map Utility and Lightroom, so it may not always be the device’s fault if the position is a bit off.
I ran into one slight gotcha. I’d set the camera options so that the camera’s time is set by the GPS device. What this does is set to the UTC time used by the GPS system. Nothing wrong with that, and in the UK it’s the same as local time for half the year, but at this time of year it’s an hour behind local time. Fortunately, Lightroom makes it easy to fix this – select all the images that have the wrong time, click the little icon next to the time field in the Metadata area and you’ll see this:
Select the “time zone adjust” option, set to +1 hours and click the Change All button. Job done.
So far, I like the GP-E2 – I’ll post a long term review when I’ve had the opportunity to get to some more places.
 And I’ll be finding out soon
 Or whatever is correct for your location
