Method Detail

milesToDegrees

public static float milesToDegrees(float miles)

readMiles

public static double readMiles(String arg)

Answer a distance in miles as expressed by arg in Double format. arg may end in "mi" (to mean miles, no change) or "km" to mean kilometres (hence multiplied by 5/8).

readNumber

public static double readNumber(String param,
                String arg,
                double low,
                double high)

readDegrees

public static double readDegrees(String param,
                 String arg)

deltaLat

public static double deltaLat(double d,
              double lat,
              double lang)

Answer a delta in degrees latitude which corresponds to the distance d [in miles] in the vicinity of the point at latitude lat and longitude lang. The answer is approximate.

deltaLong

public static double deltaLong(double d,
               double lat,
               double lang)

Answer a delta in degrees longitude which corresponds to the distance d [in miles] in the vicinity of the point at latitude lat and longitude lang. The answer is approximate.
