Well-known text representation of coordinate reference systems ( WKT or WKT-CRS) is a text markup language for representing spatial reference systems and transformations between spatial reference systems. The formats were originally defined by the Open Geospatial Consortium (OGC) and described in their Simple Feature Access [1] and Well-known ...
Well-known text ( WKT) is a text markup language for representing vector geometry objects.

Properties. Web Mercator is a slight variant of the Mercator projection, one used primarily in Web-based mapping programs. It uses the same formulas as the standard Mercator as used for small-scale maps.
