Editor to share with you what the mapbox model in GIS development is like, I believe most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

Mapbox can be like Amap or Baidu map, zoom in to a certain extent, show some simple models, and can paste some maps to achieve a flat three-dimensional effect. In the mapbox example, it shows how to load some stereo models using online slicing data on mapbox.

By downloading the data of the outline of the building on the Internet, we can also achieve the effect of loading this model. In one way, the data is converted into geojson format and loaded directly. This disadvantage is that when the amount of data is very large, the system performance consumption is also very large. The other is to slice it into vector tile and load it, just like map slices, according to the zoom range. The effect of this three-dimensional building needs to have a height field in the data, or it can be set to a uniform height.

The code is the way to load the layer, the key is to set 'type':' fill-extrusion', 'fill-extrusion-height': [and' fill-extrusion-base' 'three attributes, through the setting of base and height, can also achieve a floating effect, the specific implementation method see the official example.

However, according to the current implementation of the class library, the edge of the building can not be set, so it can not show a border effect.
