Integration Of Road Design Information With Carrymap For Mobile Access

Abstract

Today, technological advancement is a major driving force in changing the face of the spatial information around the world. High spatial resolution satellite imagery has revolutionized the Mapping discipline. The GIS database technology for storage of large datasets, data management, and analysis and update facilities has had the greatest impact on spatial information environment. This study aims at development of road design and all road features to be displayed in mobile phone application (CarryMap). The study covered Limuru and Kabete constituency’s rural roads, which are under Kenya Rural Roads Authority (KeRRA). The methodology employed in the study involved use of GIS software to develop a database which contains both spatial and non-spatial data. Cadastral maps were scanned, georeferenced, cropped and mosaicked. An overlay with high resolution satellite imagery was done to establish whether there were buildings and other developments that are constructed on the road reserves. Road design with chainage and elevation both super elevation and camber were overlaid with Kenya New Road Classification Map 2018. Using AutoCAD application, the Topographical data was imported and plotted. The plotted data was used to create road design, then the road design was imported to ArcMap so that it can be compatible with CarryMap which can be displayed on mobile phone. Using this CarryMap mobile application you can be able to know exact chainage and real-time location while in the field. Static survey was performed to connect all the roads to the National Control Network. The project has demonstrated the benefits of integrating Remote Sensing, Cadastral Survey and Geographic Information Systems approach in Land Management and Road Construction. This study has demonstrated the use of the CarryMap application as a mobile application that can be used in design and real-time monitoring of road projects.
