Smart phones, car navigation systems and now driverless cars are based on coordinates and coordinate systems. This book is about why coordinate systems work, and why they sometimes don't work. The previous editions are based on the North American Datum(NAD 83), the horizontal control datum for the United States, Canada, Mexico, and Central America, and the North American Vertical Datum(NAVD 88). By tracking the dynamic nature of the Earth, NGS will provide a new National Spatial Reference System that is semi-dynamic. It will replace NAVD 88 with a GNSS/geoid datum and replace NAD 83 with a...

This book provides a comprehensive discussion of topographic LiDAR principles, systems, data acquisition, and data processing techniques. Ranging and scanning fundamentals, and broad, contemporary analysis of airborne LiDAR systems, as well as those situated on land and in space are covered. Also discussed are data collection in terms of waveforms and their properties; error budget, quality control, and data organization; LiDAR data processing and information extraction. State-of-the-art technological developments used in filtering algorithms for digital terrain model generation are...

Earth Observations (EO) encompasses different types of sensors (e.g., SAR, LiDAR, Optical and multispectral) and platforms (e.g., satellites, aircraft, and Unmanned Aerial Vehicles) and enables us to monitor and model geohazards over regions at different scales in which ground observations may not be possible due to physical and/or political constraints. EO can provide high spatial, temporal and spectral resolution, stereo-mapping and all-weather-imaging capabilities, but not by a single satellite at a time. Improved satellite and sensor technologies, increased frequency of satellite...
