ON WAYS TO INTEGRATE MONITORING DATA OF TRANSPORT INFRASTRUCTURE FACILITIES INTO A DIGITAL INFORMATION MODELING SYSTEM

Semochkin A.V.

Abstract:
The aim of this study is to determine the technological features of using digital information modeling for integrating and describing monitoring data in a spatial-attributive framework. The article examines the specifics of developing a software module for parametric modeling of monitoring data within a digital information modeling system. It explores the decomposition characteristics of initial modeling data for the formation of step and amplitude graphs within the spatial model system. Various methods for utilizing data variance to analyze its reliability and compliance with criteria are described. The study considers visual programming methods for automated modeling of graph areas using surface networks and Gaussian curvature. The article analyzes existing approaches to assessing the current state of a construction object within the framework of 4D technology, employing tools and mathematical methods for creating numerical modeling splines in a spatial system. Special attention is given to methods for generating graphs in a spatial system based on data linked vector-attributively within digital information modeling elements and external tables. The study proposes a systematization of individual modeling technologies based on a three-step method of digital information modeling for monitoring data.
