# How to calculate north east lat/lon coordinates of a tile?

 0 HI there! I know the below code calculates the north west corner long/lat coordinates of a tile, but is there a way to calculate the north east, south east or south west corner long/lat coordinates? (I'm terrible at maths...). I'm programming in java, and any zoom around 17 - 19 would do. static double tile2lon(int x, int z) { return x / Math.pow(2.0, z) * 360.0 - 180; } static double tile2lat(int y, int z) { double n = Math.PI - (2.0 * Math.PI * y) / Math.pow(2.0, z); return Math.toDegrees(Math.atan(Math.sinh(n))); } Thank you very much! asked 30 May '19, 02:18 xj18205 36●1●1●2 accept rate: 0%

 1 I just realised I can use the NW corner of the surround tiles to work out this answer! answered 30 May '19, 03:06 xj18205 36●1●1●2 accept rate: 0%
