Development of a 3D map of city of Quy nho’n of Bindin province, R. Vietnam

Abstract

The article discusses various sources of cartographic information for creating three-dimensional maps with full assignment of metric and semantic characteristics to each object, complete filing, application, storage of attribute data in the form of a database, an algorithm for creating maps is presented in the form of block diagrams. A smart storage and management system through a system of language queries is carried out in SQL. As the main software environment, in which the processing of cartographic materials was carried out, was the geoinformation system GIS "Panorama". The resulting design solutions are presented in the form of vector graphics and visualized in 3D space. It is concluded that against the background of the growing volume of spatial information about terrain objects, structuring and storing information, including cartographic materials, is an important aspect in the effective use of data for making decisions of different levels.
