Abstract |
| Land information forms an integral part of any Land Administration System hence the need to discuss issues pertaining to data handling. Data handling techniques have evolved from the traditional land surveying using chains and plane tables to more current sophisticated methods such as the use of GPS, Lidar and Satellite imagery. It is however important to note that the techniques in use differ from country to country though often similarities are noted. At the same time, it is logical to promote methods which enable efficient execution of the data acquisition process as well as the subsequent processing while keeping costs at a minimum and maintaining quality. A complete land administration system requires that all land be surveyed and registered and as such relies on these techniques. The boundary surveys in Zimbabwe are incomplete and thus there is no seamless cadastral database available. Land surveys in Zimbabwe are based on the use of total stations traverses as the major data acquisition technique and there are set standards which regulate the operations. GPS use has been restricted within the Surveyor General’s office while there has not been significant progress in the utilisation of photogrammetry and satellite imagery for mapping. This paper discusses the current data collection and processing techniques for land surveys as well as newer or more sophisticated technologies that are being implemented in other nations and recommendations for implementing other technologies for data handling in Zimbabwe. |
