Modeling of spatial data on the construction site based on multidimensional information objects

Abstract

The article presents information modeling different types of spatial data on the construction site. The description of spatial and attribute data based on multidimensional information objects (MIO) is determined. It is proposed to use a new type of MIO called modified multidimensional information objects (MMIO). MIO and MMIO schemes are developed for each type of master planning object in the form of one multidimensional information object. Complete descriptions of layers of point, linear and polygonal spatial objects are presented, which allows simplifying the model of the structure of existing databases of spatial information processing systems. The results of the study show that multidimensional information objects allow describing in unified mathematical form sets of various types of spatial data models. The result of modeling of general planning spatial based on multidimensional information objects corresponds the modern requirements of information modeling in construction-BIM-technology and design of master plans on the new technological level.
