Come convertire minuti di laurea secondo in decimale in java

Question

Questo è un GPS fondamentalmente applicazione in cui sto ottenendo le informazioni di latitudine dai metadati di una foto in questo formato 28" 41'44.13597.

La mia necessità è quella di convertire le stesse informazioni in decimale e il fuori mostrerà i dati in formato decimale come 28,705,45 mila.

si prega di aiutare con il codice o qualsiasi riferimento

Grazie in anticipo

Answer 1

/** answer=hour+minutes/60+seconds/3600 */ 
public double convertHourToDecimal(String degree) { 
    if(!degree.matches("(-)?[0-6][0-9]\"[0-6][0-9]\'[0-6][0-9](.[0-9]{1,5})?") 
     throw new IllegalArgumentException(); 
    String[] strArray=degree.split("[\"']"); 
    return Double.parseDouble(strArray[0])+Double.parseDouble(strArray[1])/60+Double.parseDouble(strArray[2])/3600; 
} 

Answer 2

Dividere i minuti di 60. e i secondi di 3600., quindi aggiungere i tre insieme.

Answer 3

Non so di qualsiasi libreria Java che farà questo per voi, ma la formula per la conversione da gradi in gradi decimali è: gradi + (minuti/60) + (secondi/(60 * 60))

     } 
    } 

    // Decimal degrees = whole number of degrees, plus minutes divided by 60, 
    //plus seconds divided by 3600
