Latitude, Longitude to GeoPoint
Android Snippets
So how do you get a GeoPoint(int , int) from a double latitude, longitude>?
As GeoPoint coordinates are based in micro-degrees i.e.(degrees * 1E6) you can simply do the maths every time:
GeoPoint gp = new GeoPoint((int)(latitude* 1E6), (int)(longitude* 1E6));
...or extend GeoPoint():
private static final class GeoPointD extends GeoPoint {
public GeoPointD(double latitude, double longitude) {
super((int) (latitude * 1E6), (int) (longitude * 1E6));
}
}
Then it is simply a case of:
GeoPoint point = new GeoPointD(37.234569, -122.123456);
...or wrapped in a neat little 'util' class:
package com.gojade.map.util;
import com.google.android.maps.GeoPoint;
public class MapUtil
{
public static GeoPoint getGeoPoint(double latitude, double longitude) {
return new GeoPointD(latitude, longitude);
}
private static final class GeoPointD extends GeoPoint {
public GeoPointD(double latitude, double longitude) {
super((int) (latitude * 1E6), (int) (longitude * 1E6));
}
}
}
