IsWhere Image and Videos - Under Deveopment


Geotagging Imagery and Video

IsWHERE is a log of my thoughts, reflections, and news/blog links on the emergence of image and video geospatial tagging. On May5th this year, I opened a second blog to deal with more detailed aspects of tools for FalconView and TalonView can be found at RouteScout. Trends I want to try and follow are the various disruptions resulting from spatial smart-phones, how many GPS devices are out there, smart-cameras, and other related news. And yes, I have a business interest in all of this. My company Red Hen has been pioneering this sort of geomedia for more than a decade.

So beyond a personal blog, I also provide a link to IsWHERE a shareware tool created by Red Hen Systems to readily place geoJPEG or geotagged imagery and soon GEM full motion media kept on your own computer(s) into Google Earth/Map from your File Manager media selection. Works great for geotagged images from Nikon, Ricoh, Sony, iPHONE, Android and all geo-smartphones that can create geotagged images. IsWhere - read about it

Blue2CAN GPS and Nikon D Series Cameras

Red Hen Blue2CAN for Nikon D3 and D300 GPS cameras review

Pocket GPS World

Last year Nikon announced the latest in their range of Digital SLR cameras, the D3 and D300. These are targeted at the top of the range with a price tag of £3400 for the D3 (yes that is three thousand) and a slightly more affordable £1300 for the D300.

Red Hen Systems have produced a tiny Bluetooth adapter that connects to a bluetooth GPS and transmits the GPS data to the camera: the Blue2CAN. The Blue2CAN retails at $279 USD.

Both new Nikon cameras have a special 10 pin connector which amongst other functions allows you to connect a GPS to the camera. This then provides a NMEA datastream from which the camera can extract the positional information and stamp the image meta data with the location that the picture was taken.

In the last year I have reviewed a number of GPS systems that offer a mechanism to match GPS tracks to digital photos. Whilst these do work they add an additional step into the workflow and the possibility of errors creep in with each additional step. The beauty of this system is to have the camera stamp the image when the shutter is pressed.

To get started the Blue2CAN and your Bluetooth GPS need to connect to each other. Technically this is known as pairing.

The Blue2CAN should be attached when the camera is switched off. As soon as you switch on the adapter's LED will flash 3 times within a second and will then start looking for GPS devices. If it doesn't find a Bluetooth GPS then it will go to sleep for 20 seconds and then search again. This will continue until it manages to pair with a GPS. There is little feedback during this process and it can be a little disconcerting whilst waiting for it to happen.

Once paired you need to tell the camera to record the GPS position with the image. This is achieved by pressing the menu button, selecting GPS, then "Auto meter" then select "enable".

I was amazed how simple Red Hen had made this process. The main issue with Bluetooth devices is getting them paired, for some reason it is either simple or very complex. I am fortunate enough to have over 20 different Bluetooth GPS receivers and in my tests only 3 failed to connect to the Blue2CAN. These were a Globalsat BT-359, a B-Speech GPS 20C and Evermore BT GPS receivers. I suspect that this is because they need a passcode to pair.

Another interesting feature is that even if the camera is switched off the Blue2CAN will still remain active and paired to the Bluetooth GPS receiver. This enables it to instantly have the connection when the camera is switched on, a great idea! Unless of course you use the GPS with a phone or a PDA. The GPS can only connect to one device at a time. It took me a while to work out what had gone wrong with my PDA navigation, with my camera in the boot of the car the GPS was still connected so my PDA couldn't get a connection. I overcame this by luck by switching the GPS off and on again.

Although the Blue2CAN is constantly powered whilst connected I found there was more than enough power in a charge to take hundreds of pictures over a 3 day period (some including the built in flash) and still have about 30% left in the battery.

The Red Hen Systems Blue2CAN is a Bluetooth adapter for the high end Nikon digital cameras allowing the connection of a Bluetooth GPS receiver. The compatibility of the adapter was impressive, working seamlessly with a huge range of Bluetooth GPS receivers.

The installation and setup is simple and required no technical knowledge. If you are capable of operating one of these Nikon cameras then you are well over-qualified to set up the GPS for the camera.

Thanks for the insightful review.

I'm planning on getting this, but can't decide between the Holux M-241 and the EMTAC mini-s3.

Which do you think is better? Is there a different receive you recommend?

I have just got one of these for my D700. Although the manual says it needs a bluetooth device that doesn't need a code, I have got it working fine with my BGT-31, Holux M1000 and my QStarz BT-Q1000P.

All of these need a '0000' paring code entering when adding to a PC/Phone, but looks like the Blue2CAN defaults to 0000 as it works for my devices.

Good stuff as I don't need/want anymore GPS devices!
