Hello Ecke Youve got some good points. I stick with my columbus 'cause it´s so nice - and it has POI and Voice facilities as well. And it has a 1 or 2 GB memory caard - so I can use it for a long trips with no computer (the only GPS tracer with a card, I believe). The software that coes with it can make NMEA files out of the CSV files (comma seperated text files). As well as KMZ or KML files for Gogle. A KML file is quite nice - You can post it to anybody and the file will open up Google Earth and show the images there.
The JOBO Photo GPS I haven´t received yet. But I have read that its quite clever. For one it only recieves for 0,2 seconds, as the shutter is released. Therfore it has low battery consumption. Not enough time to get ALL info from the sattelites. But when you later run the files through the software (must have internet access), the softwaare will retrieve the rest of the data from the sattelites. Clever, right? Secondly, the electroniv "noise from the camera will disturb the reciever, soo the acttual recording is delayed. The JOBO allows you to adsust this delay, if needed. Anayway - my Columbus and my i-gotU is tracking all the time, which makes it a hazzle to sync the data with the images. The JOBO just records, when the shutter is fired. I'm sure you aare right about the problem with series of many FPS, but at least you woul dprobably not move very far in this short period of time, so you should be able to difine the same locaation for many shots. However, the electronic noice from the camera might ruin the whole recording. Anyway - when using the K20D exposure was so bad I had to use 3-shot bracketing most of the time. With the K-7 I don't have to anymore. This way it's esaayer to get good geotags.I hope. BTW: I wrote to HOYA today, asking them when will they offer a Pentax DSLR that supports integrated geotagging - which will write geodata directly into the EXIF data on the fly. I am awaiting their answer. As you know Samsung was going too biuld in GPS facilities in their version of K-7, which they haven't produced so far :-( I am confident that geotaagging will be HUGE. Someday soon all images will be geotagged - for database purposes - so, we can search any image database for images by drawing af rectangle on a map in a GIS-application. I need this in my work - who doesn't by the way? Regards Jens -- Treat others as you would like to be treated yourself.
