In KB "Panorama" the GIS Constructor for Qt Designer SE version 13 was developed for the CentOS 7 operating system. The new version improves the reliability of working the multithreaded GIS applications that process spatial data hosted on the
CentOS (Community ENTerprise Operating System) is the popular distribution kit Linux based on commercial Red Hat Enterprise Linux and compatible with it. The distribution kit consists of the free software with the open code. The source codes for the operating system is provided under the GPL licence. The operating system is reliable and flexible in configuration, supported by a large community of developers, thanks to which it is constantly being developed and updated.
GIS Constructor is a set of geoinformation components for use in the visual programming environment of Qt Designer, which allows you to develop your own GIS applications. The visualization of the contents of digital maps is made in conventional symbols adopted for topographic, geographical and various special maps. Geoinformation system has ample opportunities for performing calculations, for providing display of spatial data on various graphic devices in standard and user systems of conventional symbols. The main functions can be executed in multithreaded mode. It supports automatic optimization of used memory for processing large amounts of data (tens of gigabytes) on limited resources (hundreds of megabytes).
The toolkit is adapted to work on a wide range of platforms and supports operating systems such as Astra Linux SE, MSVS, CRTOS "Neutrino", "Elbrus", "Zarya", Ubuntu, Alt Linux, QNX, CentOS and others. It can be used in computer complexes with processors of architectures ARMv7, Elbrus, PowerPC, Intel x86, Intel x64 and others.

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.
