Delta state (GIS) Road network

This study is aimed application of GIS and Remote Sensing approach for the analysis of Asaba Urban Street network of Delta State Nigeria. In this study, data were obtained from IKONOS satellite images, existing street guide map and from field work using the handheld GPS. The methodology adopted included data capture which was by scanning, digitizing, and fieldwork carried out for ground-truthing, annotation and for the collection of coordinates selected points. The acquired data were processed using ArcGIS10.2 software, Microsoft Excel and the Geo-Trans 3.3 software. Results of the analysis carried out revealed that the total number of roads was 2100 while the total distance of road network in the study area was 8,092.17km.
