description The embodiment of the invention discloses a spatial query data processing method and device for an electronic map, equipment, a medium and a product. The method comprises the steps that multiple pieces of historical spatial query SQL information for spatial query of the electronic map are acquired; judging whether the query time consumption of querying the SQL information in the plurality of historical spaces exceeds a preset threshold value or not; determining the historical spatial query SQL information with the query time exceeding the preset threshold as first spatial query SQL information; determining the accuracy of the spatial query based on the attribute information of the first spatial query SQL information; the attribute information of the first spatial query SQL information comprises SQL variable values, range data, statistical information of related objects and an SQL execution plan. According to the embodiment of the invention, the accuracy of spatial query can be determined based on the attribut
