Accuracy Issues for Spatial Update of Digital Cadastral Maps

All geospatial data are updated periodically. Cadastral parcel mapping, however, has special update requirements that set it apart from other data. Mapped boundaries change continuously to fit with new survey plans. Additionally, parcels have be fitted and aligned adjoining merge them into existing cadastral mapping. This is preferably performed by a spatial adjustment approach systematically improve its accuracy over time. paper adapts methods for analysis of networks the mapping better coordinate positioning plan dimensions.
