Testing the Accuracy of Cadastral Survey Techniques: Handheld Gps Receiver and Satellite Image for Land Registration Andenet Ashagrie

The type of cadastral survey technique to be used requires technical knowledge and capacity, which should strike a balance between accuracy, cost, value of the property and resources available. Most disputes among holders of land are more related to the accuracy of cadastral surveying techniques. In contrast, the cost of surveying techniques is the major factor for a country with poor economy. Balancing these issues will be difficult for a country which has not yet implemented a modern cadastral system and has no standard surveying techniques. This book, therefore, provides a systematic accuracy test for two surveying techniques used for land registration. Handheld GPS receiver and high resolution satellite image are compared with real time kinematic (RTK) GPS. The comparisons are made for the area and coordinate of the parcel by calculating its relative percentage error and root mean square error respectively. This analysis should support any decision to choose a standard cadastral surveying technique for a country, and should be especially useful to professionals in Cadastral Surveying and Mapping fields.
