TIN Data Type
A TIN or Triangulated Irregular Network is a collection of triangularly shaped polygons each of which have a surface that touches the surface of the next geometry in the collection.
Examples:
Without specifying SRID:
CREATE TABLE tins (name VARCHAR(30), t TIN);
With specifying SRID:
CREATE TABLE tins (name VARCHAR(30), t TIN SRID 4326);
Show a line followed by an arc:
CREATE TABLE tins (id INT, t TIN);
INSERT INTO tins (id, t) VALUES (1, GeomFromText('TIN(((0 0, 5 5, 10 0, 0 0), (5 5, 10 0, 15 5, 5 5)))'));
