Accurate predictions of the characteristics of urban streets in particular with respect to the typical traffic situations are crucial for numerous real world applications such as navigation, schedulin...
In times of higher market prices of fossil fuels and to meet the increasingly environmental and economic threads of climate change renewable energy must play a major role for global energy supply. Th...
Digital terrain model (DTM) is one of the important input parameters in urban flood application. This is because it influences the flow direction, flow velocity, flood extend and flood depth. LiDAR ...
LIDAR is a powerful remote sensing technology for acquisition of 3D information from terrain surface. Algorithms used for LIDAR data in urban area are used mostly to deal with the 3D points cloud an...
Today with the fast advancement of spatial data acquisition ability, the update circle of data becomes shorter and shorter and the volume of spatial data increases more and more, and distributed stora...
The research in the detection and feature extraction of typical objects in urban areas has intensified. In existing detection technologies, it has been shown that the LIDAR technique is very promising...
Based on the character of Lidar data,this paper presents a fusion arithmetic to abstract DEM,and presents a flow to get building data from the object data. Firstly, this paper preprocesses the range i...
Currently available laser scanners are capable of performing hundreds of thousands of range measurements per second at a range resolution of a few centimeters. Despite that increasing performance, up ...
In contrast to conventional airborne multi-echo laser scanner systems, full-waveform (FW) lidar systems are able to record the entire emitted and backscattered signal of each laser pulse. Instead of c...
In 2005, the main commission of the technical services of the city of Geneva launched a study to evaluate which users would potentially be interested to integrate the third dimension in the available ...
In its report "State of the World Cities 2006/07", the United Nations states that the number of urban area inhabitants is expected to rise to almost 5 billion by 2030, constituting roughly 62% of the ...
Very high resolution space borne imagery is essential for a large scale and very detailed urban monitoring and the Quickbird sensor is one of those. It offers images with a spatial resolution of 0.6...
Almost two thirds of the world’s population will live in cities by 2030. Thus, human settlements typify the most dynamic regions on earth. To cope with this development urban planning and management...
Urban forests are important as valuable green resources to give moisture and tranquillity of mind in our living, requiring an efficient control of forest increase/decrease and growth rate. In this s...
This paper shows how the complementary advantages of GPS and cellular received signal strength (RSS) positioning methods improves hybrid location estimation performance in dense urban environments. In...
