Revision and analysis of Topographic map using Remote Sensing and GIS. Up-to-date and accurate maps are basic tool for any meaningful planning and development of any nation

      Аннотация: Topographic map are needed for every developmental activities ranging from general engineering and construction works, economic and physical planning regulation, environmental management, general planning etc. Most of the topographic maps available in Nigeria are outdated and to be revised in order to achieve the desired needs. This book presents a detailed approach on the use of Remote sensing and Geographic Information System (GIS) in revising 1;50000 topographic map. Details of how to process satellite images such as sub mapping, resampling, creation of maplist, image classification, accuracy assessment etc were treated. Statistical analysis such as error matrix, kappa coefficients were discussed in details and used in comparison of the satellite images. Diagrams, tables were included to make the study clear. We hope that this book will be beneficial to numerous researchers in this field across the globe.
