Method and device for constructing semantic association of urban land spatial three-dimensional survey data

Abstract

The invention belongs to the geography space information field, and provides a method and device constructing a city land space stereo investigation data semantic association so as to solve the disadvantages of the city land space stereo investigation data semantic association constructed by conventional two dimension land investigation data; the method comprises the following steps: extracting knowledge, information and data related to the land stereo space, and determining a concept set, a composition relation and construction rules of the land space noumenon; setting up a land space noumenon logic model of the land space noumenon according to the set concept set, the composition relation and construction rules of the land space noumenon; building the land space noumenon according to the set logic model. The method and device can provide decision supports in aspects of city land stereo utilization management, city land planning, resource and environment protection, and area coordination and sustainable development; the method and device can promote city land resource management field electron government affairs construction, and can push to realize a smart city construction long term strategy target.

Description

technical field [0001] The invention belongs to the field of geographic space information, and in particular relates to a method and a device for constructing semantic association of urban land space three-dimensional survey data. Background technique [0002] With the acceleration of urbanization, urban land has increasingly become a scarce resource, and the contradiction between supply and demand of urban land has become increasingly acute. In order to solve the above contradictions, relevant departments have proposed the three-dimensional utilization of urban land space. Practice has proved that the three-dimensional utilization of land space has greatly improved the utilization rate of urban land, and has become an effective way to realize the transformation of urban development and resolve the contradiction between land supply and demand. [0003] In order to rationally organize and effectively integrate the three-dimensional utilization of urban land, the relevant tec...

Problems solved by technology

[0004] However, the traditional two-dimensional land survey data is difficult to support the standardization, standardization and information management of many land development and construction business links such as spatial resource planning, utilization, evaluation, and registration under the three-dimensional utilization of urban land space, and cannot realize the three-dimensional utilization model. Resource optimization allocation, dynamic simulation and real-time early warning seriously restrict the three-dimensional utilization of urban land at the technical level

The specific manifestations are: the inability to express the quantity and form of space resources under the three-dimensional utilization mode, the inability to evaluate the potential and suitable uses of space resources, and the inability to realize the arrangement of space resources for production and living needs, etc.
