9.7 Object Identification Techniques for Maps and Images

Geospatial dataset object identification (term seldom used for geospatial datasets; terms more used are linkage, fusion, matching, integration, and conflation ; in the following we will also use the term matching) is a complex process that may utilize work from a broad range of disciplines that include geographical information systems, cartography, computational geometry, graph theory, image processing, pattern recognition, and statistical theory. Geospatial datasets have two physical representations that deeply influence the nature of matching: Vector representation corresponds to the use of geometrical primitives such as points, lines, curves, and shapes or polygons to represent maps or images.
