Abstract

The present application discloses a method and device for selecting a three-dimensional spatial grid based on a spatial map. The method includes: obtaining indication information for specifying the position of a display area displayed on the terminal screen through the terminal screen; Determine at least one position point on the space map in the display area; obtain the three-dimensional space grid of the position point on the coordinate plane, extend the three-dimensional space grid along the preset direction, and after obtaining the set of space grids, according to the selection instruction, from Obtain the target 3D spatial grid from the spatial grid set. Compared with the prior art, this application obtains a three-dimensional space grid according to the two-dimensional coordinates of the position point when acquiring the position point determined from the display area of ​​the terminal screen, and uses the three-dimensional grid to move towards the preset The set of spatial grids obtained after the direction is extended is displayed on the terminal screen for selection, so that the selection operation of the three-dimensional spatial grids can be directly performed on the screen.

Description

technical field [0001] The present application relates to the technical field of geospatial information organization, and in particular, to a method and device for selecting a three-dimensional spatial grid based on a spatial map. Background technique [0002] In the Beidou spatio-temporal digital twin city composed of spatial grids, it is often necessary to operate the spatial grid, such as selecting a spatial grid as the starting point and destination for route planning, or selecting a spatial grid for this grid. Query of historical data of grid, processing of existing data, etc. [0003] Due to the constraints of the interaction mode of conventional equipment, the existing spatial grid selection method cannot directly select the 3D spatial grid in the Beidou spatio-temporal digital twin city on the screen of the 2D plane. The efficiency of selection is slow. SUMMARY OF THE INVENTION [0004] The technical problem to be solved by the embodiments of the present applicat...
