CadastralUltra : a purpose-built low cost GPS system for cadastral surveying in Nigeria
Elujobade, Gbadegesin
The cost of modern survey-grade electronic and satellite technologies required for proper and professional cadastral surveying is on the high side for the average practitioners in Nigeria. The practitioners have therefore resorted to the use of approximate devices based on such technologies such as consumer-grade handheld GPS devices which are ordinarily meant for outdoor activities as hiking, biking, backpacking, mountaineering, boating etc. The use of such handheld GPS devices do result into the production of unfit-for- purpose data and also, the professionalism of the practitioners is been gradually eroded. To stem this unhealthy trend, a purpose-built, easy to use, low cost GPS system for cadastral survey was conceptualized and built through a partnership between Darelash and Unistrong. This paper presents the making, functionalities and performance of the low cost GPS system that is able to compare in accuracy of obtained coordinates with known survey grade GPS systems at a price that is less than that of the survey grade by a factor of 10.
