A large-scale urban spatial energy consumption digital map production and display method

Abstract

The invention discloses a large-scale urban space energy consumption digital map production and display method, which simplifies the three-dimensional data of urban spatial form, establishes graphics elements corresponding to the required data types, converts them into urban three-dimensional vector information data, and imports them into Geographic information system; establish a database of urban spatial energy consumption, and upload big data of spatial energy consumption in real time; connect the urban three-dimensional vector information module with the urban spatial energy consumption database, import data and image information from the database, and perform data superposition according to geographical coordinates. Export and display urban spatial energy consumption digital map. The present invention combines the urban space energy consumption data with the urban digital map system in the form of vector graphics to realize the spatial visual display of urban space energy consumption, and the spatial energy consumption of the whole city can be grasped through the digital map. Based on computer cloud data technology, the realization of Massive data of urban space energy consumption is automatically calculated and processed to avoid time-consuming and labor-intensive manual data processing.

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...
