Today at the ILMF event in Denver, Wesley Newton from the U.S. Geological Survey discussed the use of lidar for wildlife habitat modeling. The USGS works to assess the quality of habitat, population demographics, species survival, and why wildlife are found in specific habitats. The group works to model and explain the mix of wildlife [...]

The workflows of capturing and extracting digital reality from point clouds has taken some leaps forward recently, given advancements in both computer hardware and software. The increased speed at which these large volumes of data are processed, and the automation of feature extraction, greatly improve the utility of the data. While, the workflow aims at [...]

The LAS 1.4 Specification was approved by the ASPRS Board on November 14, 2011. There was a good deal of back-and-forth regarding the process and specification, nicely summarized in this column that we published in V1 Magazine regarding some contentious issue with what was proposed. Martin Isenburg, the author of the column that we published, [...]

We learned of the benefits of lidar for forestry management today at the Esri Forestry GIS Solutions Conference. Generating an accurate 3D model of the earth’s surface with lidar has many advantages over imagery, given that it’s a move toward modeling as opposed to just a photo. There is a great deal of information here [...]

The ability to capture real-world conditions with LiDAR has helped engineering design firms to get into the operation side of business. I spoke recently with Les Alby, head of partnerships at AVEVA, a leading design and information solutions software company in the plant, power and marine industries. Alby stressed that modeling inside plant detail has [...]

A team of scientists combined field measurements, airborne Light Detection And Ranging (LiDAR)–based observations, and satellite-based imagery to develop a 30-meter-resolution map carbon density for the Island of Hawaii. The work accounted for 40 vegetation types across the full one million-hectare expanse of the island. This high-resolution carbon mapping effort estimates a total of 28.3 [...]

New York will soon get an online solar mapping site similar to those developed for San Francisco and other cities. The $640,000 mapping and online interface project is being coordinated by the City University of New York, with help from the Center for Spatial Information at Hunter College, and others. Sanborn Map Company gathered LiDAR [...]
