This menu item contains modes for working with a database of 3D tiles and models:

- Import...;

- Open DB (3D-tiles);

- Close DB (3D-tiles).

Import...

The mode is responsible for data import to DB3D format from the formats:

- tile model TLS (Agisoft Tiled Mode);

- point cloud Agisoft OC3;

- 3d-model Collada (extension DAE).

DB3D format is designed for storing and displaying pyramids of three-dimensional tiles packed together with tables of metadata in SQLite format. It provides for the rapid issuance of spatial information in accordance with the requested scale and territory: by tiles, by models or by objects. The format is intended for storing data in 3D-tiles pyramids of various type, for example, GoogleMapsCompatible ((a matrix compatible with Google data in projection EPSG:3857), GoogleCrs84Quad (a matrix compatible with Google data in projection EPSG:4326). Level of scale of data details and the coverage area is not limited. Range of scales recommended for work from 10-12 to 22 level of tile pyramid. The volume of one 3D-tile of scale 12 with a pyramid to 22 level can be about 20-30 Gb.

Open DB (3D-tiles)

The mode calls the dialog for selecting and opening the SQLite database, in which a pyramid of three-dimensional terrain tiles in the DB3D format is recorded.
