Geospatial Evaluation of Building Facility in Oyo State, Southwestern Nigeria

Geospatial image acquisitions through the Unmanned Aerial Vehicle (UAV) techniques has been used geospatially to assess the Infrastructural building roof facilities of Emmanuel Alayande College of Education Campus, Oyo State, Nigeria. Unmanned Aerial Vehicle (UAV) is an aircraft without a human pilot on board, it is a veritable tool to solve numerous problems socially, and spatially which serves as an effective means of search, detection and identifying objects and the subjects of interest, as well as the precise determination of their coordinates. Drone deploy flight planning software were also used during this study. This paper focused on the building roof assessment of Emmanuel Alayande College of education Oyo. To achieve this aim, a UAV (Drone) was flied at a height to acquire the image data, which was processed using Argisoft Photoscan Professional image processing software and an orthomosaic, was acquire. The orthomosaic was analyzed with ArcGIS 10.3 and a map of building assessment of Campus was obtained. The findings shows geospatially how important is the geospatial technology for mapping roofs of infrastructure in this citadel of knowledge.
