Geoinformation is created by manipulating geographic data in computerised system. Typical applications are land registration, hydrology, cadastral, land evaluation, planning and environmental observation. Geoinformatics is a science which develops and uses information science infrastructure to address the problems of geosciences related branches of engineering. Geostatistics is a branch of Geology that deals with the analysis of mining processes through mathematical models. Evolved originally in the exploration of minerals, ores and coals, it is currently applied in disciplines such as petroleum geology, hydrogeology, hydrology, meteorology, oceanography, geochemistry, geography, forestry, environmental control, landscape ecology and agriculture. This book deals with the subject area of geoinformatics in its totality. The book is user-friendly and research oriented. It is supported with elaborate glossary of related terms, acronyms, bibliography, websites and links. The book will go a long way to serve as a perfect reference book on the subject. An introductory overview of geoinformatics, web accessibility, cyberinfrastructure and GEON project is provided. Select Case studies involving organisations like PACES, GSA and Z- GIS- Centre for Geoinformatics are made. The author of this book believes in its full utility for readers.
