Movable bridges are rare, and they tend to be engineering marvels, but the Cape Fear Memorial Bridge in Wilmington, North Carolina is an unusual case even among those. Rather than swinging or folding, its roughly 400-foot steel center span rises straight up between two towers, high enough to clear the barges and sailboats working their way toward the Port of Wilmington, then settles back onto a four-lane roadway carrying U.S. 17, 76, and 421 across the river.

A pioneering project in Poland has proved that aerial mapping, combined with Lidar technology, can be an invaluable tool for accurately mapping the green urban environment. In fact, the new, cost-effective method has been extended to encompass the country’s entire tree population. This article highlights the groundbreaking project by MGGP Aero. The company has achieved remarkable results by using advanced computer algorithms to identify and elegantly reconstruct numerous tree species from hyperspectral images. Additionally, the use of Lidar enabled multiple applications including measuring and visualizing crown height and mapping biomass. Read more...
