EverPhoto GPS Data Logger GT-800BT
EverPhoto GPS Data Logger GT-800BT
The EverMore EverPhoto is a great concept, take a GPS, and a digital camera, merge the technologies and get images with positional information. No longer do you have to rack your brains to try and work out where you took a particular photo, let the technology do that for you!
You record your tracks, take your photos and when you get home the PhotoLogr software matches the two up and displays the results on Google Earth, or even creates a web site with links to Google Earth allowing you to share your pictures with your friends.
What's in the box?
The EverMore GT-800BT comes complete with:
* The Bluetooth GPS * A USB cable * A mains power adapter * A CD containing the PhotoLogr software and drivers
This is all packaged in a rather snazzy retail box. All you need to get going apart from a digital camera.
The EverMore 800BT is a GPS Datalogger and Bluetooth GPS combined in one device. It is based on the Atmel GPS Chipset, which is often used in security applications rather than general consumer GPS devices.
On the top of the datalogger is the on/off switch (clear plastic) and two indicator LEDs. To switch the datalogger on you have to press the button for 3 seconds or so. A good security mechanism to stop the GPS activating from a knock in your pocket or bag.
Once switched on the datalogger is activated on its own. The green LED will light solidly until the GPS achieves a fix when it will start to flash slowly. A fix is when the GPS has located the satellites and knows it's position.
The blue light on the right is the Bluetooth indicator. To activate Bluetooth just press the power button again and the bluetooth LED will light solidly. When a device is connected the LED will flash.
On the side of the GPS datalogger is a mini-USB connector. This is used to both charge the battery, and also transfer the datalog to your PC.
As with a lot of these devices the base of the GPS has a rubber finish. This is good for gripping a dashboard, but if your dashboard is just that little bit slippery then the included non-slip mat will prove to be useful Using the EverMore 800BT Datalogger
What is this GeoTagging all about? Put simply it is a method of working out where a photo was taken, and saving that information to be used in a location aware application such as Google Maps or Google Earth.
The GeoTagger software uses a feature of digital images called EXIF data. You don't need to understand this other than that EXIF provides some details about your pictures embedded within the image file. This records things like when the picture was taken, the camera it was taken on, the exposure etc.
There is a definition of the standard EXIF fields, and these can be used in determining when the picture was taken. There are also fields for location, but very few cameras have built in GPS. This is where the EverMore datalogger comes in. The datalogger records trackpoints which have a position and timestamp associated with them. Match the timestamp on the GPS to the camera's picture taken time and you can find out where the picture was taken, it really is as simple as that.
