Lecturer, School of Technology
Prof. Ogao serves in the newly established centre for Faculty Excellence where his roles involves helping staff and students strive and succeed in teaching learning, mentoring, leadership and professional development.
His research areas are in Geoinformatics and Information Visualization. He has supervised PhD and MSc students in Computing, IT and Geoinformatics fields, and published widely in renowned international journals and conference proceedings.
He has served as External Examiner and Program Reviewer to a number of Universities in Kenya and Uganda. He is a proponent and trainer in use of Open Source GIS software in Africa.
Visualization of pattern, trends and anomalies in budget data. The project involves dynamically following budget allocations and their subsequent utilization in development projects. A variety of intuitive visualisation techniques are incorporated to aid in presenting and interactively exploring budget data. A temporal comparison of these trends over the last 5 years is similarly highlighted.
