Computer implemented methods are disclosed for providing geographical information to a user. One method includes observing, via location information generated or obtained through a user's mobile electronic device, a user traverse a preferred user route from the start location to the destination, and saving the preferred user route in relation to the user. The method may predict, based on past behavioral information for the user, a predicted start time of a future trip to the destination and may identify one or more routes from the start location to the destination. In addition, the method may compare, at a time relative to the predicted start time of the future trip, a duration or distance associated with traversing the preferred user route to a duration or distance associated with traversing the fastest route or the shortest route from the start location to the destination.

The embodiment of the invention provides an intelligent tower crane operation panoramic monitoring restoration method and system for an intelligent construction site. The method comprises the following steps that each camera circularly traverses and collects a plurality of images in a preset number of directions of an area where the camera is located at a preset time interval, and records a shooting moment of each image; when shooting is completed in the preset number of directions of a single round, for the single camera, panoramic splicing is carried out according to multiple images of the camera in the preset number of directions to obtain a panoramic image, and the panoramic image is stored; a tower crane operation site map is drawn, and the positions of all the cameras on the map are marked; and monitoring calling request information of clicking a target camera on a map display interface is received, and the panoramic image of the corresponding target camera is displayed. According to the on-site panoramic image acquisition mode, monitoring personnel far away from the construction site can retrieve the panoramic image of the tower crane working site in different areas, the working site condition at the appointed moment is restored, monitoring dead angles can be effectively eliminated, and the construction process is accurately restored.

According to the concrete terrace flatness continuous measurement method provided by the invention, a wheel type measurement trolley carrying an inertial measurement unit, an odometer and other various sensors traverses on the surface of a to-be-measured terrace according to a planned measurement line, and meanwhile, a total station is used for tracking the wheel type measurement trolley in real time and obtaining position measurement data; and then using coordinates measured by the total station as control points to restrain a measurement result.
