This article mainly introduces the GIS development of Mapbox Vector tiles example analysis, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let Xiaobian take you to understand.

Vector tiles is vector slicing according to translation understanding, making vectors into slices, which can quickly draw large-scale maps and provide complete map design flexibility; vector data, according to the way of map slicing, is requested to the client through web, and real-time rendering is carried out on the client side according to the style to achieve the display effect, especially suitable for frequently changing data.

Refer to the web page, mapbox English URL, the specific interpretation according to the understanding of the above translation:

In traditional map slicing, we slice the data in advance and slice the map into small pictures (for example, 256-256). The client requests these pictures and displays them according to different locations. in this way, the display map will not get stuck because the request picture is too large, but the disadvantage is that when the local map changes. We need to update the data, and then slice the map. When the level of the map is relatively high, the slicing speed is relatively slow.

Vector tiles publishes vector data directly and requests according to the corresponding level of slices. The returned data includes basic map information and style information, and is rendered on the client side to achieve the same map effect. In this way, when the data changes, you only need to update the vector data on the server.

Of course, this technology is also derived with the development of webgl technology, because the rendering speed of webgl is very fast, and the number of rendering is relatively large, so it can be displayed so smoothly.

Domestic Amap also uses this similar technology. Amap now lists the information of the map on the picture, such as poi information, so that the client requests this kind of data and draws it directly.

Thank you for reading this article carefully. I hope the article "sample Analysis of Mapbox Vector tiles in GIS Development" shared by the editor will be helpful to you. At the same time, I also hope you will support us and pay attention to the industry information channel. More related knowledge is waiting for you to learn!
