Method Summary

Modifier and Type	Method and Description
double	getAltitude() Returns the altitude in some unit.

Method Detail

getLatitude

double getLatitude()

Returns the latitude in some unit. The unit is very likely decimal degrees north, but we don't enforce that anywhere.

Returns:

the latitude in some unit.

getLongitude

double getLongitude()

Returns the longitude in some unit. The unit is very likely decimal degrees east, but we don't enforce that anywhere.

Returns:

the longitude in some unit.

getAltitude

double getAltitude()

Returns the altitude in some unit. If this EarthLocation was retrieved from a PointFeature (via PointFeature.getLocation()), then the unit can be obtained by calling pointFeature.getFeatureCollection().getAltUnits().

Returns:

the altitude in some unit. A value of Double.NaN indicates "no altitude".

getLatLon

LatLonPoint getLatLon()

Get the lat/lon location

Returns:

lat/lon location

isMissing

boolean isMissing()

Are either lat or lon missing?

Returns:

true if lat or lon is missing
