Method for manufacturing and displaying large-scale urban space energy consumption digital map

Abstract

The invention discloses a method for manufacturing and displaying a large-scale urban space energy consumption digital map. The method comprises the following steps of: performing data simplification on urban space form three-dimensional data, establishing a pixel corresponding to needed data type, converting the pixel into urban three-dimensional vector information data, and loading into a geographic information system; establishing an urban space energy consumption database, uploading space energy consumption big data immediately; connecting a three-dimensional vector information module with an urban space energy consumption database; importing data and image information from the database, performing data superimposition according to geographical coordinates, and exporting a digital map capable of displaying urban space energy consumption. According to the method, urban space energy consumption data is combined with an urban digital map system in a vector image mode, so that spatial visualization display of urban space energy consumption is realized; by virtue of the digital map, the space energy consumption condition of a whole city can be mastered; based on a cloud data technology of a computer, automatic calculation processing of urban space energy consumption mass data is realized, and time-consuming and labor-consuming manual data processing is avoided.

Description

technical field [0001] The invention relates to a method for making a digital map, in particular to a method for making and displaying a digital map of urban space energy consumption. Background technique [0002] Low-carbon cities have become the forefront of global urban development. With the rapid development of urban construction, my country's urban energy consumption has increased significantly year by year. Huge energy consumption has become a huge burden on the national economy. How to reduce urban energy consumption and use it reasonably and effectively Energy and improving energy efficiency have become important issues facing urban development at present and in the future. Urban spatial energy consumption is closely related to urban spatial form and layout, and is crucial to building low-energy cities and conducting research on spatial energy consumption in various urban land uses. Reducing urban space energy consumption is conducive to promoting energy conservation...
