Spatial Data

Spatial Data in SAI

Spatial Data is supported by Well-known text (WKT) that is a text markup language for representing vector geometry objects on a map, spatial reference systems of spatial objects and transformations between spatial reference systems.^[1]

When you define the algorithm's input in SAI you can support WKT input using the appropriate descriptions. This is an example, note that text in square brackets is mandatory:
