Abstract

The invention discloses an urban water map and a manufacturing and displaying method thereof. The urban water map is made and displayed on the basis of the GIS technology, the remote sensing technology, the BIM technology and the digital photogrammetry technology, and, in combinations with data information platform downloading, on-site survey of treading points, literature data and the like, real-time basic information is obtained. Data processing is performed on the real-time basic information by adopting land class analysis, pollution analysis, key node analysis and drainage basin analysis,then an urban water map base map and a primary urban water map are sequentially made, and map effect supplementation is performed on the primary urban water map to obtain a final urban water map. Thefinal-edition urban water map not only can effectively display the river position, but also can visualize attributes such as river pollution, river flow direction and river silting nodes. In addition,river channel, drainage basin, wetland liquidity, river pollution and possible pollution can be visually analyzed on a large scale, and on the basis, a river channel and drainage basin treatment scheme is discussed.

Description

technical field [0001] The invention relates to an urban water map and a method for making and displaying the same, in particular to an urban water map for online monitoring of urban river and watershed pollution and a method for making and displaying the same, belonging to the technical field of visual maps and making and displaying the same. Background technique [0002] With the development of society and the deepening of urbanization process, the change of urban water environment has attracted more and more attention from people. As an important part of urban ecosystem resources, urban water environment has an inseparable relationship with urban economic development and human production and life. Urban water map refers to the monitoring and comprehensive management of urban rivers and watersheds in the form of visual maps. At present, the existing urban river and watershed monitoring and governance system mainly has the following shortcomings: [0003] (1) Although the...
