The invention relates to a multi-dimensional spatial data rendering method and device, and belongs to the technical field of spatial data visual expression. The method comprises the steps of obtainingmulti-dimensional spatial data, performing type filtering on the multi-dimensional spatial data, and performing dimension filtering on each type of data to obtain two-dimensional data and three-dimensional data under each type of data; performing corresponding projection transformation on the two-dimensional data and the three-dimensional data under each type of data to obtain a vector tile and athree-dimensional tile of each type of data; and according to the dimension requirement of the display scene, performing scene transformation of the corresponding dimension on the obtained vector tiles and three-dimensional tiles of each type of data, and performing rendering display according to a scene transformation result. According to the method, unified rendering is carried out on each typeof data of each dimension, rendering efficiency is improved, scene transformation of the corresponding dimension can be carried out on the vector tiles and the three-dimensional tiles according to the dimension requirements of the display scene, display of different scene dimensions of the spatial data is achieved, and display is more comprehensive and more accurate.
