GEO tagging images is a way of using GPS coordinates to create a reference point on a map where the photograph was taken. This can be used with e-mailed images or blogs, where I'm concentrating my efforts for now.
I have been researching this topic for some time trying to find a quick and easy way to make this happen. After much research, I have found lots of somewhat useless information. Most people that have articles about it make it seem quit simple. I haven't found this to be true. As a matter of fact, I have found it to be very confusing and difficult. I want to GEO Tag photographs for several reasons; most people I have talked to really like the idea, I want to teach it in my Travel Photography Class, and last, I've been asked to provide this service to some of my clients.
I have found that there are several ways of getting the GPS coordinates needed. The first and easiest is to have a camera with a built in GPS receiver which will do the work for you. Next is to use a data logger, which I don't have yet, and last, the very time consuming way - using several programs to generate the GPS information needed for the images. The free program I'm using is called GeoSetter.
I have also found an app for Android phones called "Geotag Photos Pro" that will track your location(s) and create a file that you upload to their website. You then create a login for retreiving your data to sync to your images. The trick with this app is to make sure your camera time is precisely synced to your phone, which the app will help you do. This is good for short trips where you have a few images you need to tag.
These images below were done the hard way. Since these were taken several years ago, I wanted to see if and how I could link them. Some of the problems I have noticed, when you click on "Google Map Link", some of them will place a marker on the map and others don't. At this point, I'm not sure why but I do prefer to have the markers. The idea is to pinpoint where you were, the whole object of GEO tagging! I also want the map to be zoomed in closer to the area where the photograph was taken - working on that as well.
I will admit, knowing more about this topic now, I will be using a data logger for my trips in the future. This will eliminate several time consuming steps.
As I continue my research on this topic, I will edit and add more.
