		<abstract>This paper describes a proposed model for defining directional relationships between geometries into Spatial Data Management Systems (SDMSs) uniting the characteristics of the Cone-Based Model and the Projection-Based Model. The proposal also includes the implementation of the created model built as SDMS's extension, unlike other existing implementations which are produced in the form of external SDMS tools.</abstract>
