Quantifying Energy Demand in Mountainous Areas
Despite their rich energy renewable potential, mountainous areas suffer from energy poverty. A viable solution seems to be the radical turn towards renewable resources. Any tailor-cut energy planning for mountainous areas presupposes the adequate estimation of the energy demand of buildings, which in this case is hindered by the lack of long-term meteorological data, especially in remote, high ...
متن کاملPrecipitation Resource Potential in Mountainous Areas in Hebei Province Analysis
The climatic conditions of Hebei Province cause this area shortage of water resources, man-made factors lead it more serious. In March 2007 in Hebei , 37 mountain counties got samples of soil and corn, conducted indoor tests, through analyzing Hebei rainfall and soil moisture and corn yield in mountains, using potential resource calculated model to precipitation, they analyzed and evaluated pre...
متن کاملEstimation of Solar Radiation on Building Roofs in Mountainous Areas
The aim of this study is estimating solar radiation on building roofs in complex mountain landscape areas. A multi-scale solar radiation estimation methodology is proposed that combines 3D data ranging from regional scale to the architectural one. Both the terrain and the nearby building shadowing effects are considered. The approach is modular and several alternative roof models, obtained by s...
متن کاملEfficient occlusion-free visualization for navigation in mountainous areas
In three-dimensional (3D) navigation, if mountainous terrain is displayed based on ordinary perspective projection, viewers often find that the features of interest are occluded, which prevents an overview of the features. This paper presents an approach for the automatic generation of consecutive nonperspective views of mountainous terrain. The proposed method can generate views without occlus...
متن کاملA Point Cloud Filtering Approach to Generating DTMs for Steep Mountainous Areas and Adjacent Residential Areas
Digital terrain models (DTMs) are considered important basic geographic data. They are widely used in the fields of cartography, land utilization, urban planning, communications, and remote sensing. Digital photogrammetry mainly based on stereo image matching is a frequently applied technique to generate DTMs. Generally, the process of ground filtering should be applied to the point cloud deriv...
