Automated Attribution of Shapefile Data Through Map Merging
Stanley DallalMap merging or conflation is the process of merging two vector maps to produce a map with superior positional accuracy and richer attribution. Conflation often involves a high degree of costly manual work to match features between two maps and update their positions and attributes. ESEA has developed an automated conflation system that significantly reduces the effort involved in merging vector maps. ESEA's conflation system implements sophisticated matching algorithms to rapidly identify corresponding features between two maps and to automatically transfer attribute information between these matched features. ESEA's capabilities were used in a USGS evaluation of current conflation technology.
