AUTOMATIC GEO-REFERENCING METHOD OF A BUILDING'S SITE PLAN CAD DATA USING A PARCEL CONTOUR FROM ATTACHED CADASTRAL MAPS

摘要

PURPOSE: An automatic geo-referencing method of buildings site plan CAD data using a parcel contour from attached cadastral maps is provided to create a continuous map coordinates for building site plan CAD data. CONSTITUTION: A polygon expressed in an accumulation turning function is automatically selected in an adjacent ground boundary by suing a similarity measurement result between the boundaries extracted from a map for boundary of a building(400). A conformal transformation function is inducted by suing an azimuth angle obtained in the measurement of a similarity of a turning function and an area ratio of a lot boundary polygon(500). The polygon induced through the conformal transformation function is transformed into map coordinates(600).
