Features and Ground Automatic Extraction from Airborne Lidar Data
The aim of the research has been the developing and implementing an algorithm for automated extraction of features from LIDAR scenes with varying terrain and coverage types. This applies the moment of third order (Skweness) and fourth order (Kurtosis). While the first has been applied in order to produce an initial filtering and data classification, the second, through the introduction of the w...
متن کاملAutomatic Road Extraction from Airborne LiDAR : A Review
LiDAR is the powerful Remote Sensing Technology for the acquisition of 3D information from terrain surface. This paper surveys the state of the art on automated road feature extraction from airborne Light Detection and Ranging (LiDAR) data. It presents a bibliography of nearly 50 references related to this topic. This includes work related to various main approaches used for extracting road fro...
متن کاملAirborne Lidar Data Processing and Information Extraction
February 2007 109 continued on page 110 Lidar is changing the paradigm of terrain mapping and gaining popularity in many applications such as floodplain mapping, hydrology, geomorphology, forest inventory, urban planning, and landscape ecology. One of the major barriers for a wider application of lidar used to be the high cost of data acquisition. However, this problem has been greatly alleviat...
متن کاملBuilding Detection and Structure Line Extraction from Airborne Lidar Data
The development of LIDAR (Light Detection and Ranging) system makes the acquisition of 3D surface information more convenient and immediate than other geomatics technologies. However, the 3D coordinates of the surface features, such as the corners, edges and planes of buildings, cannot be obtained directly from the LIDAR data because of its blind characteristics. How to detect the feature locat...
متن کاملA Novel Algorithm for Road Extraction from Airborne Lidar Data
Road data in 3-dimensional forms is required for a variety of geospatial applications e.g. road maintenance, transport planning and location-based services. Although airborne lidar can produce dense point clouds from which 3-dimensional road information can be retrieved in detail, lidar data is often incomplete due to the line-of-sight requirement, and therefore a better result of information e...
