Item An Object Based Geographical Information Systems for Transportation (GIS-T) Data Model for Road Maintenance in Uganda(International Journal of Technoscience and Development, 2014) Kayondo-Ndandiko, Mazzi Lydia; Bax, Gerhard; Togboa, Sandy Stevens TickodriThis paper presents an object based Geographical Information Systems for Transportation (GIS-T) data model for road maintenance in Uganda. It is part of research aimed at accentuating the use of Geographical Information Technologies for road maintenance. Specifically, the study aimed at defining a GIS-T data model for road maintenance based on the data requirements in the sector as a process towards establishing standards for geographical datasets. This was accomplished through identification of road maintenance data requirements, review of organisational reports, workshopnproceedings, organisational terms of reference for various projects, understanding and consideration of the Information Quality Levels (IQL) and a review of existing data models and standards in transportation. This resulted into a conceptual and logical data model for road maintenance based on concepts of dynamic segmentation and linear referencing. The study concludes that understanding of the transportation network of the country is essential to adoption of the proposed model. The choice of the GIS software for the physical model implementation with a full set of dynamic segmentation tools is fundamental.
