Geographic coordinates (obtaining)
Methods to obtain geographic coordinates of a place include:
- Category:Lists of coordinates
- Manually:
- On the web:
- Multimap provides geographic coordinates of a location selected from a map.
- http://www.world-gazetteer.com provides geographic coordinates of many cities (select country - "cities" - city)
- For US coordinates, USGS GNIS service is extremely extensive. It also provides linkouts to topozone and terraserver so that you can tweak the results to your liking.
- Looking at a website built by GPS users, e.g. http://geourl.org/ or http://www.findu.com/ or http://www.geocaching.com/
- Looking for GPS "Waypoint" files
- Googleing for the city name together with "latitude", "longitude", which will give hits like http://www.infoplease.com/ipa/A0001769.html
- Looking at a wiki that uses map coordinates, e.g.http://susning.nu/
- Zooming in on the place on TerraServer-USA and getting the values at left
Regardless of the source of coordinates, good practise is to evaluate whether they appear reasonable at first glance.
