Damage to the Underground: A Stitch in Time Saves Nine
Avoiding damage to utility infrastructure could save billions. This is a summary of a white paper “Reducing Damage to Underground Utility Infrastructure during Excavation” prepared by Geoff Zeiss and Dr. Sakura Shinoaki and published by the Geospatial Information & Technology Association. Over two decades in the United States there have been more than 400 fatalities and...
Fusing Data on Doomed Ash Trees
By using fused data gathered with lidar and hyperspectral imaging, a geospatial services company helped a large utility to identify 90% of ash trees with the potential to fall into their power lines—in a timeframe that wouldn’t have been possible without the use of remote sensing. By Ian Berdie, Zach Raymer, and Mia Chen Remote-sensing...
Lidar vs.Wildfires in Southern California
After the 2018 wildfires in Southern California, lidar data was collected to enable risk-mapping assessment and planning, to identify fuel-load reduction programs, and to escalate the emergency assessment of post-fire debris flow hazards. Featured image: This lidar image was taken over Lake Casitas, California. The data are clear: Natural disasters are on the rise, and...
Making Aerial Lidar Work for Small Businesses
Aerial lidar’s growth has created challenges for small business in the aerial-data collection data; here’s how one company turned them into opportunities. Featured image: Midwest Aerial’s main lidar-flying aircraft. For several decades (1950s -1980s), the commercial mapping industry operated in a relatively stable technology environment. While numerous and important technological advances were made (most notably...
Teaching Roots and Research at the University of the Philippines
One of Southeast Asia’s oldest surveying schools is promoting the use of geospatial technologies and thriving in the digital age. When Louie Balicanta walks inside the high-ceilinged corridors of Malcolm Hall on his way to teach land surveying, he knows how much responsibility rests on his shoulders. Not only is he an assistant professor at...
The Many Facets (and Faces) of Surveying
Surveyors have traditionally done a variety of essential and interesting work—and they continue to do so. We’ve asked surveyors from various work disciplines what inspires them. To get an idea of where we are going, it’s important to stop and take a look at where we have been. This rings especially true for those of...
