Multispectral LiDAR: Deserts, Rivers, Forests, More

“Originally LiDAR was seen as a means of obtaining elevation data, but there is a growing interest among researchers in accurately mapping water/land interfaces and identifying species by spectral characteristics, which requires multiple laser wavelengths,” says Juan Carlos Fernandez Diaz, senior researcher at The National Center for Airborne Laser Mapping (NCALM).

LiDAR Sensors Meet Florida Citrus

According to Tom McPeek, CEO and founder of AGERpoint Inc., a lot more can be done with geospatial technology to spread precision agriculture into a sub-market of farmers who grow permanent crops that develop on a tree, vine or bush as opposed to annuals that grow in a field, often low to the ground.

Geo Positions: Detecting Change Over Time With 3D Models

Upon obtaining a degree in geography from the University of Dusseldorf in Germany about 10 years ago, Sandra Bond came to the U.S. as an exchange student to write her thesis on the San Andreas fault. “Then I just ended up staying,” she says. Now, a decade later, she has worked her way up to the role of geographer and LiDAR analyst with the U.S. Geological Survey (USGS).

A Total Look: The Power of GIS, 3D BIM Together

From a cost and labor standpoint, the beauty of BIM has always been its noninvasiveness.  Architects and builders can see the electrical, plumbing, heating and cabling “bones” of structures in virtual renderings, and they can determine how to build around them with minimal disruption. Because BIM can plug into an assortment of other digital technologies, it also seems natural that to extend it to work with geospatial imagery and GIS in general.

Is Linear LiDAR Still Relevant?

Much of the technology available to geospatial service providers today was completely unimaginable as little as 10 or even five years ago. That isn’t just my observation. It’s what I heard over and over again at the 2016 MAPPS Winter Conference in Las Vegas and the 2016 International LiDAR Mapping Forum (ILMF) in Denver.

Photogrammetry’s Place in the Geospatial Toolset

Photogrammetry is the science of making measurements from photographs — especially for recovering the exact positions of surface points. “The problem is that it is hard to find a qualified photogrammetrist under the age of 50,” says Darryl Murdock of the U.S. Geospatial Intelligence Foundation. “Instead, what we have are many individuals who have geographic information systems (GIS) background, but very little analytics experience or exposure to other geospatial disciplines.” Why does this matter?

Newfound Value in Drone Aerial Imagery for Real Estate

One market that stands to both give to and gain from geospatial professionals — aerial imaging experts in particular — is real estate. As image-capturing experts within the mapping field increasingly take to drone technology to modernize their techniques, their value to real estate agents continues to grow.

Gearing Up for UAV Commercialization

With the global unmanned aerial vehicle (UAV) market expected to show double-digit growth over the next five years, government agencies along with private sector companies in surveying, agriculture, energy, retail, utilities, mining, construction, real estate, news media, film production and other fields are seeking out ways to commercialize UAV technology, or to at least use it to introduce new efficiencies and cost savings into their work processes.

Drones and Privacy: Transparency is Key

As a technology that allows unmanned aircraft to fly while carrying a variety of sensors, drones are no more invasive than a news helicopter overhead or an emissions monitor with a license plate camera on the side of the road. However, due to the original use of the technology for military purposes, portions of the U.S. public are raising questions about how drones will be used in civilian life, and what will prevent someone from using a drone in a destructive or offensive manner.
