For each snapshot, the time of its creation is also known (stored in the meta information and file properties). Each track point has two characteristics: 1) time and 2) coordinate. And while shooting, start recording the route – you can easily find free programs that can do this, the main thing is that it can save the recorded tracks in GPX format. Its essence is as follows: when shooting with a camera without GPS, take a mobile phone with you, it has a GPS chip. It is the opposite of the one that will be described in this article. You can use a technique called GPS correlation. We will consider four programs at once, two of which are cross-platform and they work on Windows as well.īy the way, note to the owners of SLR cameras without GPS: if your camera does not have a GPS chip, this does not mean that your photos cannot have GPS tags. Of course, manually placing markers on the map is tedious, and in this article we will talk about programs that allow you to automate the process of building a route based on GPS data from a series of photographs. This can be used to reconstruct movement or for any purpose (calculate the number of kilometers traveled, average speed, and so on). If the photos have GPS tags, then by placing these locations in chronological order on the map, you can see the route of movement. Reconstruction of movements based on photographs
