Template:Sources-lat-long

There are a few web sites that provide useful lat/long information.

OpenStreetMap (OSM) – Browse the map, click with the right mouse button on the desired location and select "Show Address". The lat/long value of the location can then be copied from the text field in the upper left part of the website.
- Nominatim – OSM reverse geocoding
- If a destination has a geo tag, there will be a map icon at the top right of the article. If you know the area, then you can get co-ordinates for listings by going to that map (of any article), positioning the mouse pointer, then right-clicking to show lat and long info.
Wikipedia gives co-ordinates for most articles about places
Geomap – search via OSM Nominatim, provides coordinates in WV templates formats
Geobatcher is a tool which can take an entire section of Wikivoyage listings, and insert coordinates for up to 100 listings at a time. More instructions in article, How to use dynamic maps.
Multimap lets you search for cities in many countries and returns lat/long info (some problems with non ASCII chars in the names)
The Getty Thesaurus of Names has lat/long info for most cities in its database
The Global Gazetteer from Falling Rain Genomics, Inc. is another database that gives decimal geocode values for many place names around the world.
