Huang, H., 2018. Research on intelligent measurement methods of land area inundated by seawater in coastal cities under rainy season conditions. In: Ashraf, M.A. and Chowdhury, A.J.K. (eds.), Coastal Ecosystem Responses to Human and Climatic Changes throughout Asia.

At present, intelligent measurement methods for accurately measuring land area submerged by seawater with GIS is difficult. Therefore, this article proposes a kind of intelligent measuring method for land area submerged by seawater in a coastal city based on improved Zernike moment within a rainy season environment. Based on Gauss projections, our research used the arithmetic mean method and the Pauta criterion to build the measurement model, and then used the edge detection operator to detect the land edge that was submerged by seawater, through a gray-weighted operation, which provided calculations of the basic parameters of the land submerged by the sea through interlayer interpolation and the arc tangent extrapolation methods. Experimental result shows that the method proposed in this article has a high degree of measurement accuracy.
