Vector data dynamic visualization method and system

The invention provides a vector data dynamic visualization method and system, and the method comprises the steps: obtaining a map service name, a geographic vector data type in a map, and a ZXY index of a sliced map according to a map slicing request; if the cache is used, when the existence of the corresponding map slice is queried in the cache, performing format conversion and picture compression on the map slice; otherwise, converting the ZXY index of the map slice into a pixel coordinate system, and calculating longitude and latitude coordinates through pixel coordinates to obtain a longitude and latitude range of the map slice; generating MVT vector tiles according to the longitude and latitude ranges of the map slices; according to a rendering mode of the MVT vector tile, the MVT vector tile is dynamically rendered and displayed on a client browser or a server, map content can be quickly loaded and displayed, front-end rendering and rear-end rendering of the vector tile are supported, a 2000 national ge
