Moving Forward with UAS Mapping

For geospatial professionals, the most exciting aspect of the current explosion in unmanned aircraft systems (UASs) is using them for mapping, a task for which they complement manned aircraft and Earth imaging satellites. The trade-offs among these three platforms include cost, endurance, coverage, resolution, processing time and refresh rates.

Big Data Help Scientists Dig Deeper

In 2008, the U.S. Geological Survey took 3.6 million images acquired by Landsat satellites and made them free and openly available on the Internet. Dating back to 1972, the images are detailed enough to show the impact of human decisions on the land, and they provide the longest continuous view of Earth’s landscape from space.

Geiger-Mode LiDAR Delivers Fast, Wide-Area Mapping

In recent years, a new breed of LiDAR system has emerged, enabling collection from much higher altitudes and at higher resolutions. These Geiger-mode sensors differ in several ways from the traditional linear-mode LiDAR commonly used in commercial airborne systems.

Moving from Pixels to GEOINT Information

From new platforms, such as unmanned aircraft systems (UASs) and cubesats, to new sensors, such as light detection and ranging (LiDAR) technology, the amount of remotely sensed data is increasing exponentially. How do we make sense of all these pieces of data and turn them into geospatial intelligence (GEOINT)?

Consider the Benefits of Mobile LiDAR for Transportation Projects

Mobile LiDAR has become an effective solution for rapid data collection in recent years. For example, using mobile LiDAR imaging, the Utah Department of Transportation recently undertook a groundbreaking inventory of numerous roadway assets. Laser scanning is helping many state agencies comply with a new federal law requiring them to digitally map the U.S. National

Emerging Programs, Markets Drive Earth Observation Growth

Competition is expected to heat up in the global Earth observation data market, with an ever-increasing number of satellites and new companies looking to expand their business. By Adam Keith, director of space and Earth observation, Euroconsult (www.euroconsult-ec.com), Montreal, Canada. From 2004–2013, 162 Earth observation (EO) satellites were launched by civil government and commercial entities

Satellogic to Offer Real-Time Earth Observation

Last year saw the birth of many new commercial endeavors aimed at taking advantage of the widespread commercialization of space to expand the number of low Earth orbit Earth observation satellite constellations. Satellogic (www.satellogic.com) recently announced plans for a constellation of its own satellites, called CubeBugs, after successfully launching and testing two satellites in 2013.
