1. A data inquiry system for 3D location-based image, video, and information, comprising: a client device, having a space module and a first transmission module, and the space module being used for retrieving space parameters pointed by the client device, and the space parameters being transmitted by the first transmission module, wherein the space parameters are retrieved by only the space module itself; and a remote server, having a database, a processing module and a second transmission module, and the database being provided for storing a plurality of object data of a plurality of objects and a plurality of related image and video data, and each of the plurality of object data comprising an object space position parameter, and the processing module obtaining space parameters through the second transmission module, and determining a space inquiry range according to the space parameter, and the space inquiry range being a conical range that uses the location of the client device as a vertex, and the processing module inquiring and identifying an object data of the object space position parameter situated in the space inquiry range, filtering out a first part of the plurality of object data, which is smaller than a critical value, and displaying a second part of the plurality of object data, which is larger than the critical value, on the client device, wherein the second part of the plurality of object data, which is displayed by the client device, is used for enabling a user to identify an object from the second part of the plurality of object data and to further retrieve the image and video data related to the object, which is identified by the user, wherein the critical value is an access rank of each of the plurality of object data or a magnitude, which is displayed on the client device and corresponded to each of the plurality of object data, of each of the plurality of object data.
