This book addresses the latest developments in Information Technologies (IT) for geo-engineering. It contains papers from the 5th International Conference on Information Technology in Geo-engineering (5th ICITG), held in Golden, Colorado, USA, 2024. The book is divided into the following chapters: 1) Geotechnical Instrumentation, Sensor and Sensing Technology; 2) Imaging Technology, Virtual and Augmented Reality, Information and Computer Technology; 3) Data-Driven Investigation and Modeling, Big Data and Databases; and 4) Machine Learning and Artificial Intelligence. IT encompasses a broad field with extensive and powerful uses in geo-engineering, particularly in dealing with large amounts of uncertain data typical of many geo-engineering research and projects. Given its broad range and most up-to-date coverage, the book benefits students, educators, researchers, and professional practitioners, encouraging them to take the geo-engineering community into the digital age.
