As an end-to-end process, BIM delivers much more functionality to users over the life of a project than stand-alone software. However, CAD will continue to play a role in architecture, engineering, construction and operation.
“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).
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.
If you agree with the old saying, “Many hands make light work,” you understand why crowdsourcing is an excellent approach for filling gaps and improving accuracy in maps. The practice has been used online for more than a decade and has proven highly effective in identifying and updating many types of geospatial information.
The need for improved documentation for subsurface features will only continue to expand as the volume and complexity of our utilities increases along with the earth’s population. In the long run, carefully thought-out standards will reduce project costs and prevent damage and injuries, while utility specialists trained in all aspects of utility design will enhance the efficiency and safety of our systems.
Searching for new ways to apply existing geospatial technology is an important component in the continued growth of mature companies. By considering the universal benefits sought by every business, such as reducing operating costs while improving production, performance and profitability, applications in many new markets can be identified.
While the FAA has released the Notice of Proposed Rulemaking that provides some direction for commercial small UAS operations in the US, the regulatory environment remains challenging. Organizations wanting to prepare for commercial operations are faced with many gray areas as they attempt to build and manage UAS programs that comply with the requirements.
Fisheye lenses produce a panoramic image, useful for viewing wide areas in one picture. Due to the non-uniform resolution around the edges, fisheye imagery is not typically used for traditional mapping applications. However, as the quest for small light-weight payloads for unmanned aerial vehicles (UAV) continues, even cameras equipped with fisheye lenses are being considered.
In the April 2017 issue of POB, find out how 3D tools played a role in the renovation of the Institute of Civil Engineers headquarters in London. Also, POB releases the results of its 2017 3D Surveying Trends Study.
