Other tools and resources

map-making.app is only one of many tools that can be useful for making GeoGuessr maps.

MapCheckr

https://mapcheckr.vercel.app/ by MrAmericanMike and RollinHill checks all the locations in your map as GeoGuessr would, and tells you if any are broken or undesirable. This way you can remove gen 1, trekkers, or unofficial coverage from your map. If you make your map in map-making.app, you can avoid those cases initially, but over time new Street View coverage can be published or deleted, and MapCheckr can help you find out. To use it with map-making.app, export your map as JSON and import it into MapCheckr. You can do this again every few weeks or months to check for new problems.

Map Generator

https://map-generator.vercel.app by RollinHill picks random locations in an area of your choice. You can use this to computer-generate a starting point for your maps, but you can also use the generated data in other ways. For example, if you're picking locations in an area with a lot of Gen 1 coverage, you can use the Map Generator with a date filter to find out which roads have more recent, higher-quality images.

This tool is also used a lot to discover new street view coverage as it is released.

There's also the "nsj" Map Generator, an expanded version by Nur, Niels, and other community members, available at https://map-generator-nsj.vercel.app/. You can see if its additional options are useful to you. It also supports marker clustering which has better performance if you're generating many thousands of locations.

pano-tools

https://geo.emily.bz/pano-tools by emilyapocalypse can automatically assign pano IDs to existing maps to avoid unofficial coverage. You can also use it to bulk-update maps to new coverage or to remove pano IDs entirely, which can be necessary when interacting with other tools.

http://map-links.vercel.app/ by Nur finds all linked panoramas starting from one source panorama. Linked panoramas are the ones that you can get to by clicking the arrows in Street View. This tool is mostly useful if you are working with hidden coverage. You can enter one panorama into it, and find out where the hidden coverage goes.

SV-Map

https://sv-map.netlify.app/ shows the official blue lines layer, and archives blue lines layers at different dates. You can find newly covered roads by comparing the blue lines across time.

GeoGuessr Maps List Enhanced

This great userscript by Kommu makes GeoGuessr's "My Maps" listing usable, by sorting the maps and displaying them in a nice table.
