GIS database construction method for urban underlying surface runoff and runoff formation process analysis

Abstract

The invention discloses a GIS database construction method for urban underlying surface runoff and runoff formation process analysis, and the method comprises a base station detection module, a weather early warning module, a geographic data detection module and a GIS database, wherein the output end of the base station detection module is connected with the input end of the GIS database. According to the GIS database construction method for urban underlying surface runoff and runoff formation process analysis, firstly, a base station detection module, a weather early warning module and a geographic data detection module are selected in the method, so that complete acquisition of basic data can be ensured, and the data diversity is facilitated; the detection terminal platform is placed atthe boundary of each branch, the accuracy of data information acquisition is ensured, and after the information is integrated, the city comprehensive factors are acquired through the geographic data detection module, so that a city three-dimensional diagram can be completely established, the later establishment of a GIS database is facilitated, and the data is more convenient to take in for calculation.

Description

technical field [0001] The invention relates to the technical field of generation and confluence of underlying surfaces, in particular to a GIS database construction method for analyzing the formation process of generation and confluence of urban underlying surfaces. Background technique [0002] The underlying surface refers to the Earth's surface that is in direct contact with the lower atmosphere. The atmosphere is bounded by the earth's water and land surface, which is called the underlying surface of the atmosphere. It includes topography, geology, soil, rivers and vegetation, etc. It is one of the important factors affecting the climate. The underlying surface is the interface between the atmosphere and the solid ground or liquid water surface below it. It is the main heat source and water vapor source of the atmosphere. The boundary surface of atmospheric motion. Therefore, the nature of the underlying surface has a great influence on the physical state and chemical...
