The aim of this study is to develop a Geodatabase in managing road network for part of Shomolu Local Government Area. In order to achieve the aim and objectives of this research, Satellite images, road network map, road network information, picture of; road, roundabout and their coordinates were obtained using Handheld GPS. The road network was mapped using the satellite imagery. File geodatabase was created in ArcCatalog. The road network documents served as an inventory for the database which was finally created using ArcGIS 10.3.1. Query analysis was carried out on the results. Analysis such as road density and connectivity level were carried out. The zipped shapefiles were exported to ArcGIS Online to finally create a web map. The study revealed that the only federal road observed was Ikorodu Road which is the longest in terms of Road length. It also reveal that 63.8% of the roads were tarred while only 14.2% were untarred, the untarred roads were mostly road that serves as close, lane and avenue. It was observes that majority of the roads were inner street and are maintained by the Local Government. Also, there were few main roads characterized by single lane. The study also reveals moderate connectivity level of the road network and also the value of 11km-1shows the high density of roads in the study area. The study reveals the capability of GIS-database to maintain, map, monitor and manage both spatial and non-spatial data. It is therefore, recommended that government should establish GIS unit in the federal and state ministry of transport board and also encourage the local government areas to do the same for proper planning, development and management of road transport infrastructure. |
