Abstract

The invention discloses an underlying surface nested remote sensing refined drawing method for sponge city construction. 'low influence degree development 'is introduced; The invention discloses an advanced idea of a sponge city, a grade nested classification method and the like. The invention provides a novel remote sensing refined drawing technology which is suitable for sponge city constructionand is supported by an urban surface multi-source data integrated grade scale nested classification system. Sponge city construction planning, design and engineering implementation application objectives are developed, and the key technology and the multi-level proportional scale drawing and visualization method for extracting the surface water permeability, the relative slope information, the population density level and the urban function division multi-attribute information of the'pattern spot entity 'are integrated. The system can realize an intelligent calculation and statistical mappingmethod for sponge city construction target identification. The method has the advantages of being low in cost, high in classification precision and high in applicability, and the target application requirements for sponge city construction, landscape garden planning, ecological environment protection and the like are better met.

Description

technical field

[0001] The invention belongs to the application field of geographical information and remote sensing technology applied in urban planning and sponge city engineering construction industry, and focuses on solving the problems of high-precision big data collection, processing, intelligent calculation and drawing in the process of sponge city planning and engineering construction, and is used in the early planning of sponge city construction , Geographic information surveying and mapping of engineering construction and ecological environmental protection have broad application prospects. Background technique

[0002] In the 1990s, the Department of Environmental Resources of Prince George's County in the United States proposed the concept of "Low Impact Development" (Low Impact Development, LID) based on its previous research on stormwater management. As a result, Best Management Practice (BMP), Urban Green Infrastructure (UGI) and Green Stormwater Infrastructur...
