GIS based cadastral planning

Abstract

With the proliferation of digital data and the increased availability and functionally of visual based mapping products, the use of a GIS has become the logical base for a cadastral information system, or in terms of this paper a 'GIS based cadastral planner'. The Digital Cadastral Data Base (DCDB) that forms the base layer of the 'GIS based cadastral planner', has been derived from a paper based cadastral reinstatement using existing cadastral surveys and survey control. This DCDB has then been value-added to generate a cadastral information system. Since the DCDB is presented using a common or defined coordinate system, it has the ability to form a coordinated cadastre that contains all the property corners as well as the reference marks. This paper outlines the reasons and methods used to develop a GIS based cadastral planner, as well as the benefits of an all in one, visually based system for planing cadastral surveys.
