基于百度地图API地震应急避难场所信息地图化动态显示的实现

使用ASP和jQuery等语言设计完成后台数据库几百条数据快速推送前台页面的编程,且鼠标掠过前端显示页面内任意坐标点图片时会显示该避难场信息和图片。本文着重阐述其具体的实现过程。

Implementation of a Dynamic Display of Earthquake Emergency Shelter Information Based on Baidu Maps API

The government information service is increasingly dependent upon the Internet platform, which is especially important for administration during an earthquake.Earthquake information services based on the Internet platform,with the development and improvement of a national earthquake network system,have become the most important medium for providing an external service that disseminates earthquake data and information to the public.This could provide a web platform where domestic and overseas seismic scientists and technicians assemble global and local seismic data.Meanwhile,it could provide civilians with a source of general scientific information.Furthermore,a functional module such as a dynamic display module for map visualization of information on earthquake emergency shelters could display details provided by earthquake researchers to the public.The realization of quick and dynamic transmission of thousands of background data sets to the public is an urgent topic regarding the application of the Internet.This study explores earthquake disaster shelter data information,discusses the extraction of data from the database using the ASP language,and the format transmission of data into JSON data.Moreover,the specific programming process to efficiently deliver background data and information regarding earthquake emergency shelters using the jQuery function and Baidu Maps API function to the front page has been realized and explained.Furthermore,the information about the refuge field will be displayed by moving the mouse across the front page to an arbitrary coordinate point on the image. This study primarily focused on the specific process for realization of this system.displayed.This paper primarily focuses on the specific realization process of this system.
