The three-dimensional terrain model in the geographic information system is a three-dimensional dynamically changing scene, consisting of terrain, ground, underground stationary and moving objects. For its construction, a wide variety of source data can be used: a vector map, a matrix of heights, a triangulation model of the relief and terrain, a point cloud, three-dimensional models of objects, aerial photographs, and three-dimensional tiles. In addition to such a variety of source data, the process of transmitting data and displaying a three-dimensional terrain model is complicated by the large amount of data and limitations of the transmission channels in the case of using WEB applications. This entails the need to create an optimal 3D terrain model.
The solution to the problem of large amounts of data and their transmission can become a tile representation of three-dimensional data - a format that contains a pyramid of the scales of a three-dimensional model in the form of small blocks for each level. At the master class, the specialists of KB "Panorama" will talk in more detail about the tile model, as well as demonstrate the technology for creating a three-dimensional terrain model based on all the variety of source data using the company's
At the international conference, participants will be able to get acquainted with the latest Russian and foreign companies in the field of technology, equipment and software for collecting and processing geospatial data. Specialists of branch will discuss prospects of developing the market of the geodesy, mine survey and aerial photography, will visit master classes of the leading companies, will share experience with their colleagues.

In the new version, the process of forming the tiles for Big Data data is several times faster by creating a tree-like data storage structure. There are added the parameters for adjusting the quality and speed of tile formation (enable/disable smoothing for lines, polygons, titles; printer/screen view; loading maps into RAM). Possibility is implemented for cutting tiles by rasters and matrixes "on the fly", without preliminary transformation of data. It will allow to save time on additional preparation of data. The program has improved the administrator interface, added the ability to specify the path to the configuration files.
The program allows you to create tiles in the formats JPEG, PNG, PNG8, Mbtiles, BIR and GeoPackage according to the international standard OGC WMTS 07-057r7 version 1.0.0, the standard TMS and OGC 12-128r15 GeoPackage version 1.2.1. The tile data generated by the Imagery Creator program is used by the

Work of ARINC converter is improved, where the import and export operations into a map and into a database are divided. In the new version, the algorithm for simultaneous use of several tasks by the same user within the same workplace (simultaneous launch of two or more tasks) has been improved.
Complex of preparing documents of the aeronautical information is intended for the creation and maintenance of a database of aeronautical information, the formation of aeronautical maps, the designing of flight routes for aircraft and the exchange of data with other information systems. Information exchange is carried out in ARINC and AIXM 5.1 formats. The main source of aeronautical information is the aeronautical data base created on the basis of the Aeronautical Information Conceptual Model (AICM), with additions for storing the planned information and the results of the routes designing. The model is recommended by the international organization for planning and coordination of air traffic "Eurocontrol".

The considered technology includes many stages: formation of a nomenclature sheet of a map of a derivative scale, simplification of the metric description of objects, recoding objects, sequential generalization of a relief, hydrography, road network, settlements, objects of small length or area. One of the rules by which generalization is performed is that each object should be visible in the range of scales of displaying the digital map specified for it.
The main purpose of technology of automated generalization is to reduce the time required to create multiscale maps. To implement this feature, KB Panorama has developed specialized software called
