Site Location

If latitude and longitude coordinates not available, it is often possible to determine the site location based on the site name, city, and other information. One way to do this would be to look up a location name in http://maps.google.comgoogle maps and then locate it on the embedded map. Google Maps can provide decimal degrees if the LatLng feature is enabled, which can be done http://maps.google.com/maps?showlabs=1here. Google Earth can be particularly useful in locating sites, along with their coordinates and elevation. Alternatively, the site website or address might be found through an internet search (e.g. Google).

Use tab:siteloc to determine the number of significant digits to indicate the level of precision with which a study location is known.
