Geometries can optionally have Z (3rd dimension) and M (measure) values associated with each point in addition to X and Y coordinates
You will learn
You will learn the basics of multidimensional coordinate systems that introduce Z (3rd dimension) and M (measure) coordinates to geometries’ points.
Prerequisites
Step 1: Introducing Z and M coordinates
Step 2: Optional coordinates in geometries' constructors
Step 3: Storing and retrieving spatial data with Z and M
Step 4: Processing spatial data with Z and M
Optional
