GeoHex for Java
GeoHex V3 for Java implemented by CHIKURA Shinsaku.
GeoHex class can convert between latitude/longitude and GeoHex
V3: ported from JavaScript implementation by @sa2da.
Currently only #decode, #encode, #getZoneByLocation and #getZoneByCode methods are ready.
Gradle:
compile 'org.geohex.geohex4j:geohex4j:3.2.2'
or simply copy org.geohex.geohex4j.GeoHex.java into your app.
import org.geohex.geohex4j.GeoHex;
String code = GeoHex.encode(35.780516755235475, 139.57031250000003, 9);
// code -> "XM566370240"
GeoHex.Zone zone1 = GeoHex.getZoneByLocation(35.780516755235475, 139.57031250000003, 9);
// zone1.lat -> 35.78044332128247
// zone1.lon -> 139.57018747142203
// zone1.level -> 9
// zone1.getHexSize() -> 37.70410702222824
GeoHex.Zone zone2 = GeoHex.getZoneByCode("XM566370240");
// zone2.lat -> 35.78044332128247
// zone2.lon -> 139.57018747142203
// zone2.level -> 9
// zone2.getHexSize() -> 37.70410702222824
