System for constructing an urban design digital sand table

Abstract

The invention discloses a system for constructing an urban design digital sand table. The system comprises a sand table environment construction module used for constructing a digital environment of an urban design sand table; an element hierarchical display module hierarchically managing urban design elements and hierarchically displaying the urban design elements in a visualized way; a space index interpretation module for interpreting the name, algorithm and attribute of indexes in a urban design digital sand table index library; a space calculation tool module for calculating a selected range loading toolkit in the digital sand table; an offline data extraction module for extracting digital sand table data in an offline mode and exporting two-dimensional or three-dimensional spatial data; a dynamic instant editing module for editing an urban digital design scheme loaded in the system in real time. The system can conveniently import the urban design scheme into the urban digital environment, and provides a platform and a guarantee for the digital research, analysis, management and control of the urban design.

Description

technical field [0001] The invention belongs to the technical field of urban planning, and in particular relates to a system for constructing a digital sand table for urban design. Background technique [0002] Digital sand table technology is an electronic sand table technology based on RS and GIS technology, which integrates image data, vector space data, and subsequent calculation and display functions. At present, the digital sand table is mainly used on a relatively macro geographical scale, and has the following four advantages: fast and convenient generation of digital terrain; detailed and intuitive display of digital terrain; retrieval and analysis; integration of 3S systems. With the support of computer, geographic information system, virtual reality, visualization technology and multimedia technology, digital sand table has been applied in military, route planning, real estate, water conservancy engineering, fire protection, regional planning and geographical rese...

AI Technical Summary

Problems solved by technology

[0004] At present, the existing digital sand table technology is more for processing the existing terrain and economic data, but does not solve the problems of digitization and loading of urban design, nor solve the problem of multi-source big data and urban spatial form data. The superposition problem, as well as functional requirements based on this interaction of urban design schemes, urban design project management, coupling analysis of multi-source big data and spatial forms, etc.
