Sybase IQ v15.4 and higher and SQL Anywhere v12 and higher can store spatial data (data that describes the position, shape, and orientation of objects in a defined space) using spatial reference systems.
Spatial Reference Systems (SQL Anywhere)
Sybase IQ v15.4 and higher and SQL Anywhere v12 and higher support spatial reference systems, which define the space in which geometries are described. PowerDesigner models spatial reference systems as extended objects with a stereotype of <<SpatialReferenceSystem>>.
Spatial Units of Measure (SQL Anywhere)
Sybase IQ v15.4 and higher and SQL Anywhere v12 and higher support spatial units of measure, which define the units in which geographic coordinates are measured, and how these units are converted to radians or meters. PowerDesigner models spatial units of measure as extended objects with a stereotype of <<SpatialUnitOf Measure>>.
