I was hoping someone out there could provide me with an equation to calculate a 1km square (X from a.aaa to b.bbb, Y from c.ccc to c.ccc) around a given point, say lat = 53.38292839 and lon = -6.1843984? I'll also need 2km, 5km and 10km squares around a point.
I've tried googling around to no avail... It's late at night and was hoping someone might have quick fix handy before I delve into the trigonometry...
I'll be running all this in Javascript, although any language is fine.
10 km = 0.08999 radius from a certain geopoint. This calculation is only based on latitude values and applies only to geopoints with WGS84 projection.
If you want a more accurate answer you must have to calculate it by building a function of some sort. However it still don't guarantee because people even quarrel for the degrees of error. Taking altitude into account, mercator or not, etc.
The value above is just a rule of a thumb so don not use it for critical applications.
