I am an information hoarder and liked the Foursquare swarm app for checking into restaurants and other interesting places when I travel, because I love seeing the pins on the map of the places I have been and remembering places later. I have scripts running to download my check-ins and store them in a self hosted map.
But I obviously don’t need to keep giving them my location data. Are there any self hosted alternatives with that kind of international database of places?
Immich is pretty good for this if you take pictures at each location. It has a global map that shows all your photos with a heatmap-style display and a drawer that shows a grid of the photos within your viewport as you can and zoom around. It doesn’t seem like you can view a specific album on the map currently but you can at least filter the map to favorites or a date range.
