Spatial Cadastral Information System and topographic mapping of a new residential layout

Abstract

The purpose of this paper is to produce a spatial Cadastral Information System (CIS) and a topographic feature of the CIS of a new residential layout. Differential GPS has been used to collect 3D coordinates which are later used to geo-reference the base map prior to digitization. The CIS shows equally-spaced resident parcels with area of 1.2 hectares and an undulating hill to the east. Attribute information of individual parcels suggests the possibility of incorporating different government institutions into a single computer system for proper management. This could be useful in enhancing tenement rate, tax identification and collection as well as utility management without missing or duplicating entries. The possibility of updating and retrieving at will any information about any parcel such as parcels with Certificate of Occupancy could be improved. It is recommended prior to establishment of any government layout, Digital Elevation Models (DEM) and its contingents such as slope and flow direction be first made to allow ways of leveling of steep slopes. This will control water flow in case of flood.
