Method for manufacturing and displaying urban center micro heat island digital map

Abstract

The invention discloses a method for manufacturing and displaying an urban center micro heat island digital map. The method comprises a step 1) of establishing an urban three-dimensional vector map database; a step 2) of identifying an urban center micro heat island space; a step 3) of establishing an urban center micro heat island space thermal environment database; a step 4) of putting forward and establishing different map layers according to thermal environment actual measurement, thermal environment simulation analysis and urban spatial form of the urban center micro heat island space thermal environment database; a step 5) of establishing an urban center micro heat island digital map display module, respectively connecting the urban center micro heat island digital map display module with the urban three-dimensional vector map database and the urban center micro heat island space thermal environment database, and outputting corresponding urban center micro heat island digital images and data through the urban center micro heat island digital map display module according to selected data information. The method for manufacturing and displaying the urban center micro heat island digital map is favorable for urban thermal environment and heat island effect and having an auxiliary effect on urban design and urban planning.

Description

technical field [0001] The invention relates to a method for making a digital map, and more particularly to a method for making and displaying a digital map of micro heat islands in the city center. Background technique [0002] In recent years, under the background of global warming and my country's rapid urbanization, the urban heat island effect has become more and more serious, which not only affects the living comfort and health of urban residents, but also may lead to various heat wave disasters. As one of the important indicators of urban ecological environment, urban thermal environment has attracted more and more people's attention, and the need to deal with the urban heat island problem in urban planning and design is also becoming more and more urgent. [0003] At present, remote sensing image technology is mostly used in the research of urban heat island effect at home and abroad. However, the three-dimensional space in the urban center area has various forms, an...

Problems solved by technology

Existing technologies do not take into account the impact of various urban buildings and environmental spatial forms on the urban thermal environment

In addition, research on multi-dimensional and intuitive query and expression methods for information is also lacking.
