City noise 3D digital map manufacturing method

Abstract

The present invention discloses a city noise 3D digital map manufacturing method. The method comprises the steps of (1) recording the city spatial form data via a city spatial form module; (2) acquiring and processing the instant sound source information via a noise instant acquisition module, and establishing a sound source instant acquisition database; (3) carrying out the city noise three dimensional simulation on the city spatial form data and the sound source instant acquisition database via a noise three dimensional information simulation and display module, and outputting a city noise three dimensional map. The city noise 3D digital map manufacturing method of the present invention combines the sound environment data information and a computer database based on a GIS and a city coordinate system, carries out the visual representation on the noise that can not be observed by the naked eyes by the data translation, dynamically displays the needed data via a computer, can obtain the needed information visually and rapidly, and facilitates the researches of reducing the city noise, improving the city environment quality, guiding the traffic adjustment and establishing a traffic quiet zone.

Description

technical field [0001] The invention relates to a method for making a 3D digital map of urban noise, which belongs to a method for designing a 3D digital map. Background technique [0002] With the continuous acceleration of my country's urbanization process and the rapid development of cities, environmental issues have become more and more important issues in urban development, hindering the sustainable development of cities. Noise pollution, water, air, and solid waste pollution are called the four major public hazards of urban environmental problems. Urban noise is one of the environmental problems facing urban development, which seriously affects the daily life of urban residents. The prediction of urban noise at home and abroad , Noise control and protection have been extensively studied, and there have been many achievements on the origin, propagation, control and reduction of noise, but less attention has been paid to the interaction between urban acoustic environment...

Noise pollution, water, air, and solid waste pollution are called the four major public hazards of urban environmental problems. Urban noise is one of the environmental problems facing urban development, which seriously affects the daily life of urban residents. The prediction of urban noise at home and abroad , Noise control and protection have been extensively studied, and many achievements have been made on the origin, propagation, control and reduction of noise, but less attention has been paid to the interaction between urban acoustic environment, urban spatial form, and architectural spatial layout. , lack of urban noise 3D digital map production and display technology based on the acoustic environment of urban space
