Embodiment Construction
[0030] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and examples.
[0031] Considering that when the map layer is updated, there may be the same data between the new data set of the layer and the data set currently used for rendering of the layer, it is useless to update this part of the same data, this application will Consider avoiding these useless data updates as much as possible to improve layer update efficiency and avoid the impact of layer data update on map operations, thereby improving the smoothness of electronic map operations and the stability of electronic map operations.
