Most of the empirical topographic correction methods are based on the universal assumptions of the relationship between radiations and solar incident angles. The correction accuracy is hardly to be accessed quantitatively. This paper introduces a land cover adaptive C (LCAC) method for topographic correction, and verifies its advantage quantitatively. Experiments on synthetic and real remote sensing...
Surface albedo is the ratio of the light-flux reflected in all directions of the ground and the total flux incident. It is a very important surface parameters. In this paper, atmospheric correction algorithm based on dark pixel method was introduced, and corrected surface reflectance in study area was obtained after pre-processing of the CCD data of HJ-1 Satellite. The surface albedo of study area...
A key issue in wireless sensor networks (WSNs) is to achieve a required information accuracy under some physical resource constraints especially in terms of energy consumption. Intuitively, more accurate information can be achieved by using more jointly sensing nodes at the expense of more energy consumption. However, both our analytical and simulation results show that information accuracy may also...
