(For example, to plot a square object on a map, the vertices of the polygon are numbered 1,2,3,4,1, in this order) Another point for validation on data is the point in polygon, which helps in finding points lying outside a polygon. E.g., for a particular lon-lat coordinates in a city, if the point is intersecting the polygon in an odd number ...

Formulas for the Web Mercator are fundamentally the same as for the standard spherical Mercator, but before applying zoom, the "world coordinates" are adjusted such that the upper left corner is (0, 0) and the lower right corner is ( , ): [7] = ⌊ (+) ⌋ = ⌊ ( [ (+)]) ⌋ where is the longitude in radians and is geodetic latitude in radians.
