1. A map data processing method, comprising:
receiving first data encapsulated in a form of offline data, the first data being used to characterize low-frequency data in map data;
obtaining second data after initiating a first online request, the second data being used to characterize high-frequency data in the map data; and
performing merging processing on the first data and the second data, to obtain target data to be displayed in a map;
wherein the first data and the second data are obtained by a background server by layering the map data based on an update frequency of different geographic information elements and/or importance of the different geographic information elements according to a layering model, the layering model is obtained by training a model after performing feature extraction on training data, and a data source of the training data comprises a plurality of data sources with a different confidence level.
