The invention discloses a method and a device for displaying a large amount of spatial data at the front end. The method comprises the following steps: receiving an interactive operation signal of a user; determining a front-end display scale required by the spatial data according to the interactive operation signal; determining the zoom level of the front-end display scale, wherein the front-end display of the spatial data is partitioned into a small scale, a medium scale and a large scale; when the front-end display scale is the large scale, displaying the spatial data falling into a front-end display interface by adopting a dynamic data rapid pick-up technology; when the front-end display scale is the medium scale, displaying spatial data falling into the front-end display interface by adopting a dynamic aggregation technology; when the front-end display scale is the small scale, displaying statistic information of the spatial data falling into the front-end display interface in different areas in order to improve the front-end display effect of the large amount of spatial data.
