WKT is part of the list of new keywords that we saw earlier and stands for well-known text, as WKT is a text-based markup language and is human-readable. Its use is to represent objects on a map, like points, polygons, lines, and curves. WKT can express 2D, 3D, and even 4D coordinates.
However, you can now instantly recognize this point expressed in WKT:
Indeed, it is the Parisian Eiffel Tower. Congratulations!
Now, not everybody sees what the next line represents:
POLYGON( 48.858093 2.294694, 49.858093 2.294696, 49.858093 2.294740)
If it represents anything at all! And where it is! (I chose numbers randomly).
