The Nature of Geographic DataSpatial RelationshipsThese relationships are generally very numerous, may be complex, and are important.• Spatial relationships:‣• Topological relationships(independent on coordinates)for example: next to, inside‣• Metrical relationships(dependent on coordinates):for example: ten kilometres away• Non-spatial relationships:for example: Owner of, builder of.what it is near ?12
