What is the map used for Baidu migration?

"Baidu Map Spring Festival travel rush Population Migration Big Data" (referred to as "Baidu Migration") is a technology brands project launched by Baidu during the Spring Festival travel rush boom, and it is the first big data visualization project with the theme of "population migration" in the industry.

Project introduction

20 14 During the peak period in Spring Festival travel rush, Baidu launched a brand project-Baidu Migration, which enabled Baidu map positioning and visual big data to broadcast the population migration in Spring Festival travel rush. [ 1]

Baidu Migration uses Baidu map and Baidu Eye's LBS open platform to calculate and analyze its LBS (Location-based Service) big data, and uses innovative visual presentation methods to show the trajectory and characteristics of China's population migration before and after the Spring Festival for the first time in the industry.

The 20 15 version of "Baidu Migration" was launched on February 20 15 15. Compared with 20 14, it has achieved a comprehensive upgrade in functions, including population migration, real-time flight, airport fever and station fever. The dynamic map of Baidu migration includes the national population movement and ranking during Spring Festival travel rush, real-time flight details, and the distribution and heat ranking of national railway stations and airports. Through the dynamic map of Baidu immigrants, we can intuitively determine the source and destination of immigrants.

A new highlight of "Baidu Migration" 20 15 is the addition of "Baidu Eye" function, which is a real-time flight information query product developed by Baidu based on Baidu map. Through Baidu Sky Eye, you can see the real-time dynamics and location of aircraft nationwide. Click on the icon of the flight to query, and you can also view the specific information of the flight, including take-off and landing time, model, aircraft age and so on.

The launch of Baidu Eye has turned the cold flight information of previous flight query software into a visual full-graphic interface, which not only makes it easier for family members who pick up and drop off the plane and travelers who fly home to grasp the latest flight information, but also intuitively understand the current location of the flight, which is also a brand-new presentation form of Baidu map, big data technology and traditional travel information.

June 5438 +20201October, Baidu Migration 3.0 launched a new migration trend chart function. This upgrade includes the function of specifying the migration trend map of a city: after selecting the "migration destination" or "migration source" of a city in turn, you can view the migration trend of the peak migration population in Spring Festival travel rush from the first day of Spring Festival travel rush to yesterday, which is more intuitive and clear.

At the same time, the upgraded version will expand the designated city analysis sources and destinations from the previous 10 to 50. [ 1]

As an innovative project, "Baidu Migration" hopes to serve the scientific decision-making of government departments through the innovative application of big data, endow sociology and other scientific research with new observation perspectives and methods and tools, and create opportunities for the public to get close to the value of big data and popular science data.
