Object Fusion in Geographic Information SystemsPresents four different 'fusion' algorithms for fusing together distinct objects that represent the same 'real-world' location. Overview: Object Fusion uses spatial location (latitude, longitude) as a global identifier for merging objects from two different geographic databases. The techniques used to determine if two different spatial locations can be considered equivalent are those typically used in the GIS field (for the same purpose). In essence these techniques can be classified as nearest-neighbour techniques in which different criteria (or thresholds) are used to determine if two locations are 'near' enough to be classified as the same location. Algorithms:
