A method and system for making and displaying a digital map of urban global energy consumption

Abstract

The invention discloses an urban global energy consumption digital map making and displaying method and system. The method comprises the steps of acquiring urban block power consumption data and urban road fuel consumption data; importing urban three-dimensional vector information data into a geographic information system to form a base map module of a digital map; performing automatic simulative analysis on the acquired block power consumption data and road fuel consumption data; and establishing digital map layers with different attributes for urban global energy consumption data and an urban global energy consumption analysis result, and displaying the urban global energy consumption digital map after performing data superposition on the data and image information according to geographic coordinates. According to the method and system, the urban global energy consumption data is combined with an urban three-dimensional spatial form in a vector graph manner, so that the urban global energy consumption can be conveniently subjected to spatial implementation positioning and spatial form coupling analysis; and the method and system are oriented to the field of urban planning and building design engineering practice, so that urban engineering practice and urban construction decision-making management can be assisted.

Description

technical field [0001] The present invention relates to a digital map, and more specifically to a method for making and displaying a digital map of energy consumption in the whole city, and a digital map system for energy consumption. Background technique [0002] At present, low-carbon cities have become the forefront of global urban development. Urban development is facing important issues such as how to reduce urban energy consumption, use energy reasonably and effectively, and improve energy efficiency. In terms of spatial distribution, urban energy consumption is mainly divided into static energy consumption of urban blocks and dynamic energy consumption of urban roads. The static energy consumption of urban blocks is mainly measured by building power energy consumption, while the dynamic energy consumption of urban roads is measured by motor vehicle oil consumption. Energy consumption is the main measure. Electricity energy consumption and petroleum energy consumption...

Problems solved by technology

[0004] At present, many cities at home and abroad already have dynamic energy consumption measurement and information monitoring systems for urban roads, but they are generally used for urban road information management and traffic flow control. Combining the two for analysis and research from the perspective of the city as a whole, especially the lack of visual map display applications and related patents for city-wide energy consumption
