Digital camera with GPS capability
"Jose Marques" wrote in message ... On 2007-10-23 00:52:23 +0100, said: What about other brand name cameras, such as Nikon and Canon? Nikon D200, D2-series etc. have GPS support. An optional (MC-35) cable will connect to serial interface Garmin and other brand GPS. A dedicated GPS is available from a third party: http://di-gps.com/di-GPS/n2.htm This fits in the hot-shoe or on the strap. a review is available he http://www.naturfotograf.com/GPS_review.html I personally use a stand-alone GPS unit (not connected to the camera) then merge the information after the fact using GPSPhotoLinker on a Mac. See: http://oregonstate.edu/~earlyj/gpsphotolinker/ this matches position to image based on the time the image was taken and interpolating track information from the GPS. Is there anybody who has tried connecting a tomtom GPS to a (Nikon) digital camera? Is there any way to do that? Cheers, ink |

You REALLY need a better GPS. Mine is usually accurate to a few feet! If I go on a trip, and return home, it won't go to 00 until I actually put the car under the carport. Leaving it in the driveway (20 feet) won't do. whoosh! If you're in your carport and take a picture of an object half a mile away (with a GPS enabled camera), does the "00" refer to the position of the camera or the position of the object? Now if you're using a camera that records the direction that the camera was pointing, and that can also record the subject's distance in the EXIF data, I suppose that the subject/object location can be determined with a trig. calculator. Not with a great deal of accuracy, but to a better resolution than half a mile. I suppose the problem would be significant should one have a long telephoto lens, and being taking pictures from a mountaintop. I recall taking some nice shots of the mountains on Hawaii from the top of another mountain on Maui.... Quite a distance, but that adds another dimension to the needed numbers, altitude. sigh. |

The Spider Well, because many of us would like to later return to the scene, and can't recall WHERE it was, exactly. It also makes the story of your once-in-a-lifetime trip more interesting if you can tell WHERE the picture was taken so someone else can also go there. Not many people are organized enough to write down that information for every picture. |

More important what the **** do you do with the other data beyond the latitude and longitude? Nothing is what. The Spider Many of us DO use the EXIF information. Just because YOU don't doesn't make it useless for the rest of us. |

While we're getting picky, if he's talking about photographs of the ground
from the air, those would be AIR photographs. A photograph of something in the air taken from something else in the air is an aerial photograph. "Ron Hunter" wrote in message ...

Isn't there some software available where you leave your GPS recording your
track then download that when you get home, the software then links each image to the position by getting the date / time from EXIF - I think it was clever enough to allow for any error in the camera time setting. MB |

MB Yes, there is such software, and it will allow some correlation between the GPS and camera, after the fact, but it still won't help with camera direction, or altitude. I have never, personally, used my GPS tracking data, but it is there if I want it. |

Dale There are a few options for geocoding photos: you can get a GPS logger and use separate software to match time-stamps in order to determine photo location, or you can get a bundle with the logger and software together. The altitude data I have gotten is pretty good - I've even used it on a plane and you can clearly see the takeoff and landing when visualised in Google Earth. (NOTE: Do not use Bluetooth on a plane without checking with the flight staff.) I've reviewed a number of GPS loggers, with and without photo mapping software included. Unfortunately very few loggers support the Mac. You can see a list of my reviews at http://scilib.typepad.com/techreviews/reviews-list.html -- Richard Akerman |
