If you have a camera body that does not have built in or attached GPS receiver, your files will not have location data included when the files are imported into your post processing program. You can could shoot a few shots with a camera that does gave GPS. That could be a phone, tablet, P&S camera...etc. You would then cut and paste the location data from the location aware shots onto the files that are missing GPS coordinates. Another approach is to use a device as a GPS location tracker that records a GPS location every x minutes and puts it into a file that can be exported in the GPX format. That tracking file can then be used to put lat/long coordinates by comparing the GPS time to the camera time. If any are you are using a dedicated GSP device to create the GPX logs that you use to process photos, what device are you using? If you are using a phone or tablet to do the GPX log creation, what app are you using on that phone or tablet? Any and all feedback appreciated!
