This paper presents a method for airport detection from optical satellite images using deep convolutional neural networks (CNN). To achieve fast detection with high accuracy, region proposal by searching adjacent parallel line segments has been applied to select candidate fields with potential runways. These proposals were further classified by a CNN model transfer learned from AlexNet to identify...
The history, current status and future program of the Chinese Meteorological Satellite, i.e. Fengyun satellite (FY) is introduced in this presentation. Currently, there are 2 FY polar satellites and 3 FY geostationary satellites are in operational. The type of the instruments amounted on FY satellites includes the optical imager, the atmospheric sounder, the microwave imager, the atmospheric composition...
A fast variational fusion model based on partial differential equation (PDE) is presented for pan-sharpening. The functional is constructed with several energy terms. The gradient energy term is created by calculating the gradient vector field of the panchromatic image. The visualization energy term is used for improving the perceptual effect and the spectral preserving energy term is designed for...
Two phases of remote sensing image data of Dandong city taken respectively in 1989 and 2001 were interpreted through ERDAS software and the change of landscape pattern was analyzed with three categories of indices from the landscape pattern and landscape levels by means of using FRAGSTATS software. The results showed that the construction land was dominant and expanding tendency was obvious with glebe,...
The passage based on the wild practical work in the sample survey of rapeseed, at first analyze the application of “3S”Technologies in agriculture and analyze Hubei regional situation and the reasons of rapeseed sample survey fully. Then introduce the Sample survey of general steps in the Field and the Notices in the Operating process. And then summarize the advantages of “3S” technologies in Agricultural...
The investigation of the state of land-use/land- cover (LULC) is very important for daily cadastre supervisory work and it is an important foundation link of land management. It is also an important base of the research of land-use/land-cover change (LUCC), as well as pre-processing of monitoring of forest health and simulation of dynamic evolution of natural vegetation landscape. A land classification...
