After you register spatial columns as layers, you are ready to supply them with spatial data. As noted in Where spatial data comes from, there are three ways to supply this data: use a function, called a geocoder, to derive it from attribute data; use other functions to derive it from other spatial data; or import it from files. This chapter:
For information about functions that can derive new spatial data from existing spatial data, see Functions that generate new geometries from existing ones.
