Mathematical Model of 3D Maps and Design of Information System for Its Control

Abstract

This article describes how to create an information system for storing 3D models of architectural complexes and urban districts on the example of the pre-war Stalingrad. The information system allows you to manage files, models, photos and video materials, plans and maps of urban neighbourhoods, the text information of a historical nature. Also it allows to place 3D model on the plans and maps circuits connecting the geographical coordinates from the model geometry. For data management information system it was started to develop web-based interface to the PostgreSQL database server and the Express development environment based NodeJS platform. The paper describes the mathematical model of the binding three-dimensional models to geographic coordinates related to the coordinate conversion based on the scale of the map data and the resolution of the image file with her image.
