New Sony GPS Camera Accessory

Anyone heard of any leanings in that direction? Actually, I believe you don't need their hardware. I develop GPS based applications, and thinking about it, if you have a tracklog recorded in a given format (NMEA is common to most, if not all, GPS devices), it shouldn't be difficult to write an application that goes through a folder where your pictures are stored and match the date picture was taken from the EXIF, and get the coordinate from the tracklog file at that time, and write back to the EXIF. I would create such a software easily, but I doubt that nobody thought about it yet. Cheers Padu well someone thought it was good enough to make a product!!!! Perhaps there is something to it, though I can't imagine a LARGE numbr of people having a requirement like this.. real estate military surveyors reporters who have a large number of images and travel lots ???? Apparently it links with Google-Earth, so you can go to a spot, and then look at the photos you took there. Not a very practical purpose, but I'm sure if you look at who a lot of Sony's customers are (cashed up 20-somethings who like gadgets, and will buy anything so long as it says S O N Y), that there will be quite a few who would go for such gizmos. Quite handy if you need to bury something in the middle of a forest, desert or snows cape and find it again. |

It is potentially a method of automatically tagging every picture you take with the location on earth where it was taken. I guess if you don't want or need this information it has not much use. |

Really just the outdoor pics, and of those, just the ones that you took long enough after powering up the GPS for it to have acquired signals and figured out the coordinates. This can take up to 12 minutes, depending on how long it's been since you last used the thing. |

It seems though that the software that comes with it will interpolate so that even indoor pictures can be tagged (at least approximately).

I didn't notice that info in the specs.The Pharos GPS I have for my laptop usually takes max 15-30 seconds to start up and orient itself. |

It seems though that the software that comes with it will interpolate so that even indoor pictures can be tagged (at least approximately). Hmmm... I'd rather have no data than a guess. Really just the outdoor pics, Even outdoors, the GPS system doesn't work well under trees. Foliage is not transparent to the signals, resulting in multipath, phase changes, and positions that can be off by miles. and of those, just the ones that you took long enough after powering up the GPS for it to have acquired signals and figured out the coordinates.

I didn't notice that info in the specs.The Pharos GPS I have for my laptop usually takes max 15-30 seconds to start up and orient itself. Probably depends on the unit. My old Eagle Explorer gets a fix in a couple minutes when powered on after months of sitting in a drawer, but it's quicker if I use it more often. Paul Allen |

Anybody who travels and has trouble reconstructing the location of each shot later. I just came home from the Queen Charlotte Islands with 600 images that were mostly taken at remote Haida village sites that haven't been occupied since the smallpox epidemics of the 1800's. I took notes on what villages we stopped at each day, but tagging all those images with locations later was laborious. A technological fix for that problem is tempting, although having more gear to lug around while clambering in and out of the Zodiac, wading ashore onto a rocky beach, and traipsing through the mossy woods is not. :-) hmmmm heres an idea.... if you could photograph say... a city from multiple anges with full GPS data including elevation..... I would think some clever software could give you amazing 3d photogrpahic renderings. It would need to deal with the inherent uncertainty in the position data. It's possible to get centimeter accuracy with really expensive gear, but the normal handheld GPS has an uncertainty in the tens of meters that changes constantly as the satellite constellation changes. come to think of it, one of my customers used their camera to record every inch of Melb. GP to make photo realistic game textures..... GPS data would probably be pretty usefull there too! just think aloud.... well in text! Yeah. Let your fingers do the thinking. Paul Allen |

well someone thought it was good enough to make a product!!!! Perhaps there is something to it, though I can't imagine a LARGE numbr of people having a requirement like this.. snip An idea to be sold to the masses has to be simple enough not to require much interaction from the user, and that's what I think it is. They sell the idea that everything is "integrated". I'm almost getting the motivation to research what is on the market already that works with any GPS and any EXIF enabled camera... hmmmm heres an idea.... if you could photograph say... a city from multiple anges with full GPS data including elevation..... I would think some clever software could give you amazing 3d photogrpahic renderings. The guys from Microsoft Research labs are already doing that... I've watched a demo of their software and it is really incredible. They use a database of pictures taken from several different cameras from several different angles and that is used to build a 3D model of a city. come to think of it, one of my customers used their camera to record every inch of Melb. GP to make photo realistic game textures..... GPS data would probably be pretty usefull there too! just think aloud.... well in text! maybe it is the time (as a software developer) to develop some applications in this area huhn? I'll think about that. Cheers Padu |

Apparently it links with Google-Earth, so you can go to a spot, and then look at the photos you took there. Not a very practical purpose, but I'm sure if you look at who a lot of Sony's customers are (cashed up 20-somethings who like gadgets, and will buy anything so long as it says S O N Y), that there will be quite a few who would go for such gizmos. Google earth is a revolution, they opened their API for anyone to use. One of the consequences, for example, is smugmug. They are able to use google earth in their webpage to show pictures of a given location. I found it very useful. For example, before going on a recent trip to santa barbara, calif., I took a look at the pictures/locations using smugmug/google and I found some nice shooting locations. The inconvenience right now is that you have to enter coordinates for each individual picture. If there was a way to automate and include coordinates into the exif, that service would be expanded immensely. Cheers Padu |

"Unspam" Quite handy if you need to bury something in the middle of a forest, desert or snows cape and find it again. Isn't that the concept behind geocaching? |
