Because of the complex, diverse and varied of spectrum of wetland and spectral confusion with other land cover classes and among different types of wetlands, it is difficult for Wetland information extraction automatically. In this paper, we proposed a new hybrid approach for coastal wetlands automatic extraction based on “spatial & spectral” or “Tupu” coupled information. Due to the coastal wetland...
With the rapid growth of population and the acceleration of industrialization and urbanization, the living conditions of human are getting worse. In order to make decisions scientifically and maintain the sustainable development ability of society, more new technologies and concepts should be introduced and applied. Through the powerful ability of processing spatial information and simulating the...
The Super Sketch-Pad (SSP) is a dynamic geometry software of China, which is a Chinese version designed for the teaching and learning of mathematics. This paper mainly introduces its motion driving mechanism, some application in dynamic geometry, locus, and trace, and so forth. SSP lead students to understand the geometrical characters of graphs visually, to see the beauty of geometry and to enhance...
