Description

Multi-dimensional data achievement display method and system for basic surveying and mapping production Technical Field The invention relates to the technical field of data result display of mapping geographic information, in particular to a multidimensional data result display method and system for basic mapping production. Background The basic mapping results are collected from the outside industry to the inside industry, and various data results are formed. Common achievements on the field side comprise point cloud data and image data, and the field side further generates vector diagram data, three-dimensional model data and the like on the basis. The results are repeatedly called in the scenes of planning and design, engineering construction, geographic information service and the like, a user can look up space forms and details, and can look up element attributes and analyze the element attributes to a certain extent, so that the result display is not only 'openable', but also 'understandable, alignable and inquireable'. In practical delivery and application, two-dimensional vector results, three-dimensional model results, point cloud results and panoramic image results often need to be used in combination, wherein vectors are used for expressing a range and an element structure, three-dimensional models are used for expressing a space form, point clouds keep dense space sampling information, and panoramic images provide field visual angle supplement. In order to facilitate circulation, multiplexing and sharing in units, result management and display gradually evolves to centralization and platformization, and particularly under a private cloud environment, uniform organization, uniform calling and uniform display of multi-source results are expected to be realized on the premise of meeting intranet security and uniform management and control.
