| − | | |
| − | [[Coordinates]] are a set of numbers, [[Latitude]] and [[Longitude]], used to define a location, or [[waypoint]].
| |
| − | | |
| − | ==Format==
| |
| − | There are four commonly used formats for [[coordinates]]:
| |
| − | * DDD° MM.mmm' - Degrees and decimal minutes - used in [[geocaching]]
| |
| − | * DDD° MM'SS" - Degrees, minutes and seconds - used in general naviation, particularly nautical navigation
| |
| − | * +/-DDD.dddd° - Decimal degrees, with North and East being positive, S and W negative.
| |
| − | * UTM - [http://www.uwgb.edu/dutchs/FieldMethods/UTMSystem.htm Universal Transverse Mercator] - UTM would be a better system to use for geocaching, because it's more accurate and, being based on the metric system, it's better suited to terrestial applications. However, even though [[geocaching.com]] lists UTM as well as [[Latitude and longitude|Lat/Lon]], very few cachers or [[waypoint_management_software|waypoint management programs]] seem to use it.
| |
| − | | |
| − | ==Datum==
| |
| − | [[Coordinates]] are based on a [[datum]].
| |
| − | Geocache listings use the [[WGS84]] datum, and your [[GPS]] needs to be set to this.
