Baidu map based water flow situation display method

Abstract

The invention discloses a Baidu map based water flow situation display method. According to the method, firstly, access is performed by using a Web browser on a system back-end management platform; a 'city switching' button is set to rapidly replace city information corresponding to a current map view; secondly, two modes for displaying a water flow situation range are set; then, the number of water flow situation records within a certain convergence zone is displayed at the current level in a map zooming mode; finally, specific situation information and summary information of all recent water flow situation records within the current zone are displayed on a page, and water flow situation values reaching or exceeding the preset danger level are marked with red in a table and are marked with different colors on a map. The Baidu map based water flow situation display method can obtain the given range in a real-time water flow situation information table and the water flow situation information within a given time and uses round markers corresponding to colors to perform visual display on pages according to situation level values.

Description

technical field [0001] The invention belongs to the fields of geography and hydrology, and in particular relates to a method for displaying water flow situation based on Baidu map. Background technique [0002] With the acceleration of urban construction and the continuous increase of construction scale, urban rainstorm and flood disasters are becoming more and more frequent, causing heavy human and economic losses. The formation of urban waterlogging is closely related to the drainage status of urban drainage systems. Therefore, strengthening the construction of drainage pipe networks has become especially important. [0003] The urban drainage pipe network system is an important urban infrastructure. Its function is to collect and transport urban sewage and runoff generated by the city and snowmelt in a timely manner. It has the dual functions of protecting the environment and reducing the burden on the city. With the acceleration of urbanization in our country, the const...

Problems solved by technology

However, it is usually limited to the monitoring of a small number of points, and the limited monitoring data cannot know the operating status of the system well, and provide decision-making information for the operation optimization and control of the overall system of the drainage network.

This has resulted in a passive situation in which the current drainage system "only monitors but does not control" and can only be dealt with afterwards

[0005] As the foundation of the drainage system, most of the collection and management of water flow information is carried out by government agencies using professional data collection equipment and fixed at a certain point all the year round. Due to the constraints of human and material resources, the collected data is not comprehensive and not timely.
