Title:
METHOD FOR MEASURING MUDFLAT ELEVATION BY REMOTELY SENSED WATER CONTENT
Document Type and Number:
WIPO Patent Application WO/2018/153143
Kind Code:
A1
Abstract:
A method for measuring mudflat elevation by remotely sensed water content, comprising the following steps: measuring a soil surface spectral value of a mudflat area by using a full-band spectrometer, analyzing the relationship between the spectral value and the soil water content of the mudflat area, and building a remotely sensed water content inversion model by using a statistic correlation method; selecting a water sensitive band in remote-sensing data, and inverting the soil water content of the mudflat area; similarly, analyzing the relationship between the soil water content and the mudflat elevation by using the statistic correlation method, building a relationship model of the mudflat water content and elevation, and applying the model to a satellite image to obtain the mudflat elevation. Mudflat surface water content is inverted based on remote-sensing images, and the mudflat elevation is indirectly obtained; the method has characteristics of low costs and high precision.
