KB "Panorama" received a certificate of conformity for the software product the GIS Constructor of geoinformation systems (GIS Constructor for Qt Designer), operating under the 64-bit operating system "Astra Linux Special Edition" versions 1.6 and 1.7. The program is certified in the information security certification system of the Ministry of Defense of the Russian Federation for compliance with the requirements of the governing document of the State Technical Commission of Russia, including the control of absence of undeclared capabilities and for compliance with real and declared functionality in the documentation.
GIS Constructor is a set of 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 allows you to implement in the developed GIS applications a direct connection to large spatial databases (millions of records) by using the support of DBM format. Information from the database is displayed in the form of vector maps of the area. GIS application will be able to simultaneously edit the contents of databases connected directly and through the GIS Server, carry out exchange of information between different databases, agree the coordinates and attributes of objects in different databases, jointly display information from different databases in the form of graphic layers, combine data with images , matrixes of heights, vector maps and data from various geoportals and web services. Spatial information from the database is displayed in the form of cartographic conventional symbols, which makes the editing process transparent for the user. The set of displayed and edited objects and their semantic characteristics can be flexibly specified using an SQL query.
GIS Constructor contains an API in Python language that provides access to several thousand functions of the MAPAPI-interface for spatial data analysis, automation of processes of creating and updating digital terrain models. There are several options for using scripts as part of a GIS application: a visual component of designing, a program interface of a call from the C/C++ language, direct writing and execution of Python scripts. Due to the fact that the Python scripting programming language has a large set of connected modules, the user receives an easy-to-use and extensive auxiliary toolkit (mathematical calculations, processing of text and graphic data, work with a network and another) when creating a GIS application.

The improved task of connecting geoportals allows you to optimize the display of popular third-party sources of spatial data (OpenStreetMap, Yandex,
The ability to save geoportal data into a pyramid of MBTiles tiles or into a raster for a user-selected territory for further offline use on mobile devices in the absence of the Internet has been implemented. In order to increase the speed of data access for the WMS protocol, data caching in the form of tiles has been added. In the developed mobile applications, a cache of data from geoportals will be automatically saved on the device and used in the absence of the Internet. In order to update previously saved data, it is possible to set the geoportal cache lifetime in seconds.
Access to geoportal archive data has been added. Examples of such geoportals are the Sentinel Hub geoportal or the VEGA service. The task allows you to connect to images or data on the geoportal by specifying the date, the request period, or the percentage of maximum cloudiness of satellite images. Into the list of geoportals the geoportal of Krasnodar territory has been added containing the layers: Administrative territorial division, Contours of fields of agricultural land, Fishing grounds, Vine plantations. The new version of the toolkit provides tools for implementing access to dynamically expanded geoportals (for example, KB "Panorama"). When choosing such a geoportal, you need to submit a GetCapabilities request to the service and, based on it, build a list of current data to be presented in the form of a tree of available layers.
In toolkit the algorithms for processing and displaying data have been improved. The number of supported sheets for multi-sheet maps has been increased by 4 times. The accuracy of transparency calculations for vector objects and a polygon object - colored glass - has been increased. The algorithms for interaction with the GIS Server have been improved, for example, the interaction mechanism when editing maps containing a small number of objects. The list of available MAPAPI methods has been expanded. There are implemented the methods for constructing the intersection of multipolygons in the form of a multipolygon and creating map objects using coordinates from a text file. Ability to display only error messages in the diagnostic protocol has been added. This allows you to effectively determine the cause of abnormal behavior of a program that performs a large number of operations with spatial data. In this case, limiting the output by error messages reduces the size of the resulting protocol and makes it convenient for further analysis.
The functioning of the developed mobile applications in conditions of limited amount of available RAM has been improved. The need for the program to work in conditions of a small amount of system resources becomes relevant when using the embedded devices, portable laptops, specialized tablets and other similar devices. If there is a lack of memory, the GIS core automatically activates a buffer with a limited amount of memory and performs all operations with data using only this buffer. As a result, memory consumption by the GIS application is drastically reduced. The new version adds the ability to explicitly set a limit on the amount of memory used by the application for opening the data, when it is reached, this mode will be activated forcibly.
Display of sea maps according to the S52 standard has been improved. There is clarified the implementation of procedures for forming depth values based on attribute values for underwater obstacles, taking into account the underlying objects, a requesting the code of the displayed symbol and the display flag taking into account the depth of the obstacle and requesting the code of an isolated underwater hazard with a depth less than the safety contour.
As an example, the program includes the source texts of the mobile application GIS "Panorama Mobile" for OS Aurora. They can be taken as a basis at creation of own mobile application in the C++ programming language with use of tools of Qt and QML. GIS "Panorama Mobile" allows you to jointly display vector maps (topographic, operational situation, marine navigation, aeronautical), matrix and raster data (Earth's remote sensing data). Modern packed formats of vector maps SITZ, MAPZ, MPTZ are supported, which are decompressed in RAM on the fly. The user can dynamically control the visibility of each layer for easy viewing and analysis of spatial data. Popular spatial data geoportals (OpenStreetMap, Yandex, KB "Panorama" and others) can be used as cartographic substrates. Connecting geoportals allows you to receive cartographic information anywhere in the world when determining the current location and recording the route from the built-in GPS / GLONASS receiver. GIS "Panorama Mobile" allows processing data formats of desktop products (
GIS Constructor for the domestic mobile OS Aurora is a set of geoinformation components based on the cross-platform interface for working with spatial data MAPAPI and the Qt framework, which allows you to develop your own GIS applications for mobile devices based on the Aurora OS. Visualization of the contents of digital maps is carried out in conventional symbols adopted for topographical, geographical and various special maps. Geographic information system has ample capabilities for performing calculations, ensuring the display of spatial data on various graphic devices in standard and user systems of conventional symbols. Basic functions can be performed in multi-threaded mode. Supports automatic optimization of used RAM for processing large amounts of data (tens of gigabytes) on limited resources (hundreds of megabytes).
