Problems solved by technology

However, water transparency estimation still faces challenges in coastal waters and inland lakes, because there are various types of water bodies in these regions due to the large spatial and temporal changes in bio-optical properties, and the original scheme cannot adapt to the complexity of the region. The calculation of water body transparency cannot effectively monitor and evaluate water quality

Abstract

The invention discloses a transparency calculation method and system for water bodies in coastal and inland waters, and relates to the technical field of water color remote sensing. The method comprises the following steps: collecting spectral data of water bodies of coastal and inland waters; performing clustering analysis on the spectral data, and dividing the water body into different water body types according to an analysis result; selecting corresponding preset transparency inversion models according to different water body types; and calculating the spectral data by adopting the preset transparency inversion models to obtain the transparency of the water body. According to the scheme, water transparency calculation can be suitable for water bodies of coastal and inland waters with complex optical properties, and the scheme has the advantages of large-range waters, real-time data synchronization, continuous observation and the like.

Description

technical field [0001] The invention relates to the technical field of water color remote sensing, in particular to a method and system for calculating the transparency of nearshore and inland water bodies. Background technique [0002] Water quality in inland and even coastal waters continues to deteriorate due to climate change and increased human activity. Therefore, effective water body monitoring is of great significance for the protection and management of aquatic ecosystems. Water transparency is an effective indicator for monitoring and evaluating water quality, and it is usually expressed as the depth of the Sephardt disk (Z SD ). [0003] At present, water transparency inversion algorithms can be roughly divided into two categories: empirical methods and semi-analytical methods. Empirical algorithms typically use a combination of blue, green, and red bands as independent variables to estimate Z SD , but this method only works in certain regions. Semi-analytica...
