ДОСЛІДЖЕННЯ ПРОСТОРОВИХ СИСТЕМ УПРАВЛІННЯ БАЗОЮ ДАНИХ ДЛЯ РОЗВИТКУ 3D-КАДАСТРУ

Abstract

Due to the development of world technologies, users of land resources and facilities that exist on them are aware of the need to radically change the ways of information content of cadastral systems, the organization of these works and the need to introduce a 3-dimensional cadastre. The 2D inventory is no longer able to reflect the true state of objects due to increasing requirements for accuracy and interconnection of information, namely on the ground, underground and above ground. The suggested 3D-cadastre is considered as an information element of the state land cadastre with underground parts of buildings and communication networks that go beyond the aboveground part of the land. For the 3D-cadastre to function, it is necessary to provide an integrated spatial database management system, which will be the basis of a 3-dimensional cadastre. It is determined that one of the main factors of 3D-cadastre, which is not taken into account in the modern existence of land cadastral information is the volume of the object and taking into account the complexity of the terrain, which in turn causes incorrect functioning of 3D-cadastre. In addition, there is an equally popular factor, namely, taking into account time, that is the information about the object over time. In the operation of 3D-cadastre, it should be noted that all cadastral information must be integrated, in other words, the relationship of all data, which, when superimposed, creates a single land cadastral information through the formation of a database management system in three-dimensional space. Existing land cadastral information is a basic component of the 3D-cadastre, which should be filled with information and create a database management system that will display the 3D-cadastre. The use of ordinary cadastral information to ensure the completeness of 2D-cadastre data is sufficient. Most of the parameters of land cadastral information in 2D format are quite suitable for 3D-cadastre. The introduction of 3D-cadastre will be used in land management, administrative and urban planning works. A separate and important place in this system is given to 3D-registration.
