Hello michael. In this example, i have two coordinate. Coordinate 1 = (-8.3833333333, 43.3666666667, NaN)
Coordiante 2 = (-6.9666666667, 38.8833333333, NaN) Calculate the distance I use the GeodeticCalculator: GeodeticCalculator calculator = new GeodeticCalculator(DefaultGeographicCRS.WGS84); calculator.setStartingGeographicPoint(punto1.x, punto1.y); calculator.setDestinationGeographicPoint(punto2.x, punto2.y); double valueDistance = calculator.getOrthodromicDistance(); the result distance is 511894.631746389 this value is degree,meters,radians..... what measure is this value? Many thanks. -----Mensaje original----- De: Michael Bedward [mailto:[email protected]] Enviado el: miércoles, 03 de junio de 2009 9:31 Para: Preciado Venero, Abel; geotools users Asunto: Re: [Geotools-gt2-users] method distante to class coordinate (jts) Hi Abel I'm not sure if you're working with the Coordinate class form the JTS library or the Coordinate class from the GeoTools unsupported/geometry module. As it happens, the answer is the same for both... The distance will be in whatever units you are working with :-) Please note however that Coordinate assumes Cartesian (planar) coordinates. So the distance method, which does uses simple Pythagorus calculation, will return inaccurate results if you are actually working with ellipsoidal coordinates such as lat-longs. In the latter case we will send you back to GeodeticCalculator again !
