This is a very cool project / startup! I'm curious, how do you get the ground truth data? Is that just you marking down where you are as you walk through the store?

Thank you! I tried to keep it interesting but not get lost in rabbit holes.
We have around 300 hours of ground-truth data now, in 1-second intervals, which we use for algorithm training and refinement. The same as performing a survey, our team marks their location on the map, then walks to the next location, and through post-processing we can correct any errors and interpolate the locations in between. You can see this process in the diagram with the large black dots, where the user marked their location.
