Baidu migration behind Data Tile Rule analysis (custom layer)

Note: The article is just curious to do the testing, not applied to the business, have the need to contact the relevant company.

Baidu migration products come out, its visual effect quickly get everyone's recognition. ，

However, we all know that the normal map tile data, is a variety of data overlay, how can be able to do such a clean map.

So you want to analyze this visualization effect.

Found that Baidu's map slicing level is very high, not static, but can dynamically support slicing. It is known from the style parameters it supports.

Styles=t:water|e:all|c: #044161, T:land|e:all|c: #091934, T:boundary|e:g|c: #064f85, T:railway|e:all|v:off,t:highway |e:g|c: #004981, T:highway|e:g.f|c: #005b96 |l:1,t:highway|e:l|v:on,t:arterial|e:g|c: #004981 |l:-39,t:arterial|e: G.f|c: #00508b, T:poi|e:all|v:on,t:green|e:all|v:off|c: #056197, T:subway|e:all|v:off,t:manmade|e:all|v:off,t: Local|e:all|v:off,t:arterial|e:l|v:off,t:boundary|e:g.f|c: #029fd4, T:building|e:all|c: #1a5787, T:label|e:all|v:o Ff,t:poi|e:l.t.f|c: #ffffff, T:poi|e:l.t.s|c: #1e1c1c

As you can see from this, you can close some features. such as water systems, vegetation, notes and so on. Of course, the use of these parameters can also be related to the opening and color settings of the elements.

Have to admire the service capability of Baidu map.

Here is a list of photos to download. The effect is strong. (which closes the layer features of the high-speed and provincial lanes, the current tag does not know how to close ...) ）
