Abstract

The invention provides a method for establishing an urban river network water body spectrum library. According to the method, urban river network water body spectrum data and other multi-source data are organized, put in the library, queried and displayed, and spectral signature analysis and a water quality remote sensing retrieval technology are carried out on the urban river network water body spectrum data and other multi-source data. The urban river network water body spectrum library is invented for the specific requirements that urban river network water body remote sensing water quality monitoring and evaluation is wide in range and long in monitor time, condition queries according to time, places, spectral signatures and other types are achieved, meanwhile, the function of carrying out a query according to a map is achieved, and the spectrum library achieves the function of displaying and outputting the queried multi-source data. The spectrum library achieves matching on unknown spectrums, achieves evaluation and optimization on a water quality parametric inversion model, and achieves evaluation on water quality through the water environment quality national standard GB3838-2002.

Description

Technical field:

[0001] The invention relates to a method and application for establishing an urban river network water body spectral library, and belongs to the technical field of water environment remote sensing evaluation and monitoring. Background technique:

[0002] Water resources are one of the basic elements for human survival and development. With the increasingly serious problem of water pollution, water quality monitoring has become a major issue that must be solved for sustainable economic and social development. Hyperspectral water quality remote sensing assessment and monitoring is to establish the inversion process of water quality parameters by studying the relationship between the reflection spectrum characteristics of water bodies and the concentration of water quality parameters. It has the advantages of wide monitoring range, fast speed, low cost and easy long-term dynamic monitoring. Moreover, some pollution sources and pollutant migration characteristic...
