Joys of Geotagging

Dear friends,

After my recent holiday to Scotland, I ended up having a few hundred images taken over a span of 6 to 7 days and had the onerous task of having to catalogue them. Once the images were organised in a date-wise folder, it was up to managing and mapping the names of places to the images from a separate piece of planner or itinerary.

This works well at a higher level to document the places one has visited, but certainly does not help if one chooses to return to the exact same spot at a future date or even share the knowledge with a friend, where the image was made, like it happened in my case.  Many a times during my holiday, I had pulled to the side of the road and shot a certain picture and these were generally tagged as the nearest name of a village or a place. 

After extensive search online, I had figured that the easiest way to Geotag one's images is to have an App on one's phone and synchronise the date/ time on the App and the Camera and then start shooting images after launching the App on the phone when ready to start a "trip." Once the trip is finished, the data from the App and the images from the camera have to be synchronised to arrive at a "geotagged" image. And there are many Apps one could find on the App Store that would do this.

 

However, I came across a wonderful App called gps4cam pro and downloaded the same from the App Store for £2.49. What is wonderful about this App is that one does not need to synchronise the date/ time on the App and the Camera - it is quite easy to forget this fact when one is travelling to a different timezone. Instead, one starts the trip on the App when setting out and go about shooting pictures as normal. When finished, one just need to generate a QR code from the App for the trip. A QR code is a type of matrix barcode or a two-dimensional barcode, a kind of optical label that is machine-readable. One would then take a photo of this QR code from the App with the same camera with which the pictures were shot. 

There is a simple 4 step process:

  1. Launch gps4cam on your smartphone by pressing "Start a new trip"
  2. When you are done, end your trip and generate a QR code
  3. Photograph the QR code with your camera
  4. Upload your picture and use the free gps4cam desktop software to geotag your photos

Below is one of the images I had taken today to test the App

When viewed on the map, I was able to appreciate the accuracy of the app and now I am convinced that images coming on to my new galleries will be more accurate in terms of location. Below is the location on the map where the above image was made (within the square area, the other Pins denote the other sets of images from my trip)

I would be happy to hear your own experiences with Geotagging.
