Presenting a webapp to track your location on a photo of a physical map
Those big signs with a map and a "You are here" dot can be quite useful when navigating a park, city, or new location in general; they could be even more useful if you could carry them around with you and see your location moving on the map!
This talk will be a quick presentation of a new webapp designed to do exactly that: after adding 3 calibration points the gps location can be transformed to image coordinates and shown directly on the map. More points can be added to manage maps that are not drawn to scale.
The app is implemented in Svelte and designed as a PWA (Progressive Web App), meaning it can be used from a browser or installed to a smartphone, and it can work completely offline as well.
This is an eaely look into a personal project that will hopefully grow larger in future.
