Aerial photogrammetry is generally low altitude flight, which is easy to operate in airspace and will not be affected by extreme weather. At the same time, it is not limited to the needs of take-off and landing sites. It only needs to select a relatively flat site for take-off ...
As we all know, aerial photogrammetry technology is playing an increasingly important role in urban planning and construction. Moreover, compared with the traditional topographic survey technology, aerial photogrammetry technology has the advantages of small volume, light ...
After the LiDAR data is obtained, the data can be post-processed only after data preprocessing. After the data preprocessing, there is a data checking software to conduct a preliminary check on the data results. The general data format check has the follo
Lidar (light detection and ranging) is an optical remote-sensing technique that uses laser light to densely sample the surface of the earth, producing highly accurate x,y,z measurements. Lidar, primarily used in airborne laser mapping applications, is eme
LIDAR (Light Detection and Ranging) technology and processing is used in a wide range of research and practical applications. With its ability to measure dimensions, distances, textures, and many other aspects of targeted subjects, LIDAR processing has be
Aerial photographs are a little different than the photos you might take with your own camera. The primary aerial photographic product is a high-resolution (39 megapixel) digital color photograph. Depending on the camera lens, photos can be taken in black
AUTHORS: Leah A. Wasser How LiDAR Works LiDAR is an active remote sensing system. An active system means that the system itself generates energy - in this case, light - to measure things on the ground. In a LiDAR system, light is emitted from a rapidly firing laser. You c...
On the afternoon of April 30, the first press conference of the 2020 Mount Everest elevation measurement was held at the Everest Base Camp, and the 2020 Mount Everest elevation measurement was officially launched.
With the continuous development and progress of earth observation technology, and the continuous diversification of means for obtaining spatial information, the use of a single means of spatial data resources has been difficult to meet people's infor
Recently, at the second forum on remote sensing application technology held in Beijing, China's autonomous remote sensing image processing software has made great progress. With the development of remote sensing technology, remote sensing application
LiDAR(Light Detection And Ranging) technology is a rapid development of active remote sensing technology in recent 20 years. Different from the working mechanism of passive optical remote sensing, LiDAR can effectively detect the spatial structure and topography of forest veget...
This article provides a very brief introduction to geographic information systems (GIS) technology and the unique kinds of GIS data files that enable such technology. Most data management professionals are more experienced with “classical” tabular data in Cartesian (rows and ...
