How LiDAR is Being Used to Help With Natural Disaster Mapping and Management

Michael Shillenn, vice president and program manager with Quantum Spatial outlines three projects where LiDAR data from the USGS 3D Elevation Program (3DEP) has been used to assist in planning, disaster response and recovery, and emergency preparedness.

How GIS Helps Drive Hydrography Data

There are more high resolution maps of the Moon and Mars, than the seafloor. Largely because of high costs and challenges at every stage of data gathering and processing. However, GIS-driven technological innovations have the power to change this with improved navigation and positioning systems and geoprocessing in real time for faster accurate surveys.

LiDAR: Light Detection And Ranging

LiDAR is an acronym for ‘light’ and ‘radar,’ a tool developed to detect targets and to use reflected light off of objects as a kind of visual sonar. Light Detection And Ranging (LiDAR) can determine how far objects are away from each other by shining a laser onto a target and analyzing the […]

Wearable Cartography – Portable Mapping System

Researchers from MIT’s Computer Science and Artificial Intelligence Laboratory have developed a portal mapping system that transmits remotely a digital map of the wearer’s environment.  The concept behind the technology is known as simultaneous localization and mapping or SLAM and previously had only been applied to mapping by robots. The device was […]
