Using GIS in Landscape Archaeology
Landscape archaeology is a discipline where space is critical to understanding ancient settlements and human use of ancient space. The use of GIS is steadily growing as a tool in this field.

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 […]

Smart Tree Logging with Remote Sensing
Treemetrics is using satellite imagery, UAV, and LiDAR to help forestry managers to map out forests in order to better assess the quality and value of their forests and to cut down on waste.

LiDAR and the Archaeology Revolution
Changes in how archaeologists study the past are being brought about by advances in LiDAR technology. Through the use of LiDAR, archaeologists are now able to uncover more of the ‘lost’ New England of subsistence farming from the 1700s.

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 […]

Data Capture in GIS
This article provides a brief overview of the GIS data collection process along with examples of methodologies for GIS data capture. Pre-processing Data in GIS When working on a GIS project, the first issue or decision that cartographers have to face is how to incorporate data into the system. This […]

Fabric Engine: 3D LiDAR Rendering Via Web Browsers
Fabric Engine enables developers to create compute-intensive web applications with comparable performance to native, multi-threaded applications. Fabric Engine achieves this by tapping into all of the processing power of the user’s computer – something that normal web-based applications cannot do. For the GIS market, this means that any web programmer […]

Making Maps in the Dark
Aerial surveying company Bluesky International is using next generation thermal survey equipment to capture highly accurate measurements of relative heat loss from building and other structures across the UK at night. The resulting thermal maps provide municipal authorities and other organisations with intelligence with which to address fuel poverty, reduce […]
