coverage date maps
i maintain coverage date maps of every country and dependency available on google maps using my own map-generator fork. you can view the maps here, or download them and import them into map-making.app.
maps get updated approximately every month (last update: 2023-09-04). contains over 2 million locations to ensure that it is in a reasonably high resolution.
faq & updates
why are some locations in the wrong country?this is because i use a fairly low-resolution geojson for country boundaries. there should barely be any issues (say, 1 in 2000 locations at most), but it may happen. old versions of the maps had more issues due to how map-generator worked, but since i rewrote it from scratch, this should be resolved.
what's up with the 2007-01 entries that are clearly wrong?google maps apparently uses 2007-01 as the date when they are missing data. nothing i can do about that sadly
why is data so much more sparse in some parts of a country?each iteration of the map builds on the previous version. in cases where coverage has been added after the first version, this results in a more sparse dataset, although new areas will also start filling up with each update.
how often are these maps generated?once every month or so. i don't have the generation automated because making these maps requires an insane amount of api calls, and i want to make sure that i am being at least somewhat responsible with my api usage.
i have a suggestion to improve your mapsjoin my discord! i am always looking for ways to make my tools more useful ^^
