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. You must add the tag that identifies WKT information. This is an example, note that text in square brackets is mandatory:
