This section describes the types, methods, and constructors you can use to access, manipulate, and analyze spatial data. The spatial data types can be considered like data types or classes. Each spatial data type has associated methods and constructors you use to access the data.

For a high level description of how the spatial data types are related, see Supported spatial data types and their hierarchy.

For compatibility with other products, SQL Anywhere also supports some SQL functions for working with spatial data. In almost all cases, these compatibility functions use one of the spatial methods to perform the operation, so a link to the underlying method is provided. See Spatial compatibility functions.
