Lidar (also written LIDAR, LiDAR or LADAR) is a remote sensing technology that measures distance by illuminating a target with a laser and analyzing the reflected light. Although thought by some to be an acronym of Light Detection And Ranging,[1] the term lidar was actually created as a portmanteau of “light” and “radar”. Lidar is popularly used as a technology to make high-resolution maps, with applications in geomatics, archaeology, geography, geology, geomorphology, seismology, forestry, remote sensing, atmospheric physics,[4] airborne laser swath mapping (ALSM), laser altimetry, and contour mapping.

LiDAR Use for Site Selection

LiDAR Use for Site Selection

In this case, a city needed to locate a site for a new 6-million-gallon water tank. Criteria included a parcel size of at least 3.7 acres to accommodate construction without excessive cut/fill or shoring requirements; preferably undeveloped land to avoid conflicts with constructed properties; elevation between 4,700 and 4,720 feet to

Landfill Gas Treatment Systems

Landfill Gas Treatment Systems

Prior to conversion, limited treatment is required for direct use of landfill gas (LFG) in boilers or engines. Primary treatment steps may include dehydration and filtration to reduce moisture and particulates, as well as hydrogen sulfide and/or volatile organic compound (VOC) removal.

Advanced treatment is required to produce high-BTU gas for

Using LiDAR for Water Resources Management

The Northwest Florida Water Management District, charged with responsibilities for water supply, water quality, flood control, and ecological protection in Florida’s Panhandle, needed better topographic information to fulfill its mission.

The district partnered with other agencies to fund a comprehensive LiDAR project and share the data publicly. “The need to develop

How LiDAR Technology Helps Manage Water Resources

LiDAR is a remote-sensing technology similar to radar. A hybrid of “light” and “radar,” it is also written lidar, Lidar, or LIDAR since consensus on its status as a word or acronym is yet to be reached. While radar uses radio waves, LiDAR measures distance and color by illuminating a

From the Ground Up

At the western base of Utah’s Wasatch Mountains, a narrow urban strip approximately 120 miles long and 6 miles wide is home to 80% of the state’s population. Known as the Wasatch Front, this linear metropolis includes Provo, Ogden, Salt Lake City, and scores of smaller towns and cities, with

New Tools to Measure Environmental Benefits of Watershed Restoration

Join The Freshwater Trust to explore new tools to measure and track environmental benefits from various watershed conservation and restoration projects.

The main focus will be the StreamBank® BasinScout suite of tools, which are used to coarsely survey large landscapes and watersheds to estimate the potential for different types of environmental
