AI Technical Summary

Benefits of technology

This technology allows us to integrate street maps from different sources into an urban map system by combining them together through specific standards or designs that improve their quality. It also includes features like geographic location identification (geolocation) tracking devices along roads, which helps gather accurate driving directions over time. Overall, this innovation enables better understanding of traffic flow patterns across various parts of our world's transport network more accurately than previous methods such as digital elevations models.

Problems solved by technology

Technological Problem: Current methods for integrating BIM with geospatial systems require significant effort due to their lack of consideration about how these elements affect physical environments surrounding buildings during actual use or when they're being constructed over time.

Abstract

The invention discloses a municipal administration road BIM design model and a GIS data integration method, and relates to the field of three-dimensional road model integration. The method includes following steps: firstly, acquiring a road BIM design model in a LandXML format, decomposing road model entity elements, and defining a road extended model through the element mapping and an ADE extended frame; executing semantic analysis to discrete sampling data, and converting to acquire the whole road design elements and an object geometric model; finally, according to the different levels of the visual contents, executing the integration exhibition to the road extended model data in three-dimensional software. The method is capable of using the CityGML standard as a foundation, combining the content of the municipal administration road BIM design element, extending the model and building a new road ADE model. Integrity and structural accuracy of macroscopic GIS data and microcosmic road BIM data element integration are improved, and a frame and a feasible path are provided for the integration of the road BIM and GIS data.
