In KB "Panorama" the GIS Constructor of version 12.0.3 is developed for operating system Astra Linux Special Edition (release "Smolensk"). The new version is adapted to work with the Qt framework version 5.5. This enables developers to create modern user interfaces with use of Qt QML and Qt Quick modules in combination with high-speed digital data access logic implemented on the basis of C ++ and the MAPAPI interface. By using the combination of Qt Location module for obtaining geographical coordinates and access interfaces to digital data the GIS Constructor extends a set of data sources for creating and updating maps.
The source texts of GIS applications written with using the software product the GIS Constructor and Qt framework are cross-platform and can be used for assembly for a wide range of devices: desktop, mobile and embedded. Adaptation of existing GIS applications for work with new versions of GIS Constructor and Qt require a minimum of efforts due to preserving the interfaces of the graphic components of the GIS Constructor and the interface for accessing digital MAPAPI data. The graphical components of the program are adapted for use with the new version of the environment for the development of graphical interfaces of Qt Designer.
GIS Constructor implements support for a single geoinformation space managed by spatial data servers (
GIS Constructor supports various coordinate systems and projections, provides ample opportunities for creating and adding of user conventional symbols. Visualization of the contents of digital maps is made in conventional symbols adopted for topographic, geographic, cadastral and other types of maps.

In the "Classifier Editor" in the "Layers" bookmark, there is added the ability to set the order of displaying objects within a given layer (the button "Objects order"). It allows to unite layers of the same-type in the classifier which have been entered earlier for management of order of objects display. Flexible setting of the classifier simplifies the preparation of libraries of conventional symbols according to the requirements adopted in the national mapping systems of different countries.
The sorting of multi-sheet maps (MAP) is accelerated by 3-4 times due to multi-threaded processing on multi-core processors. When sorting map objects, the order of displaying objects in the layer is taken into account.
The task "Import of navigational data from GPX files" is improved. The program allows to load simultaneously several files in format GPX onto one map. This will save operator time on converting data.
In the complex of geodesy calculations there is implemented the storage and editing of data on documents that establish the category of land, the type of permitted use and the address of land use not only for the formed, but also for the specified, changeable and original sites. Screen elements are added for entering and editing information about a natural object. The procedure for analyzing the initial data specified by the user for the formation of the scheme for the location of the land plot on the cadastral plan of the territory was automated.
In the program the dialog "Image color adjustment" was refined, which is called via the menu item "Options\Colors" in tasks of "Data lists" or "Map legend". There is implemented the possibility of creating and editing a set of the user palettes to control the displaying the matrixes of terrain elevation that were added into the document.
In the task of "Check of vector map quality" the output of report documents into the HTML-file is added. Outputting reports into HTML file allows you to generate reporting documents without using office programs. There is added the ability to run several instances of GIS "Panorama-Editor" for execution of control of various vector maps with the issuance of reports into HTML format (a report into MS Word is executed only from one program).

The program provides caching of information from a spatial database in the form of a cartographic representation already in established conventional symbols. This allows you to maximize the speed of multi-user access to this data. In the new version, for each GIS Server connection with the geo-spatial database, a separate directory can be assigned in the disk space for cache placing. This approach allows the server administrator to flexibly distribute the load to the disk subsystem.
The GIS Server allows not to reread from the database the previously received information and stored in the cache, even if this information has not been accessed for a while by any server client, or even if the GIS Server has been restarted. If data logging is available in the database, the GIS Server updates the data in the cache only in the part of the data that has changed since the previous access to the spatial data base. Logging of operations is carried out using an additional table in the database - "Log of data changes". The period of poll by GIS Server of the table of changes log is installed by the manager in program settings.
If the logging of operations is not performed in the spatial database, then the GIS Server must update the entire cache. To minimize the time and resource costs required for this operation, the new version introduces the notion of "time of data relevance". Now the cartographic representation generated by the original data set (geospatial database table or SQL query) is not recreated until the established interval of relevance of the received data has expired, even if during this period the operating system or the GIS Server was restarted. After the time of data relevance expires, the cartographical representation will be automatically re-configured if there are active connections to this data set on the GIS Server. If no one is connected to the dataset and the data timeliness has expired, the cartographic view will be re-formed at the first access of the user to this set. The relevance time for the data set of the spatial database is determined by the administrator of the Server GIS based on what spatial information is contained in this set, how much and how often it is updated for the server's clients.
GIS Server provides remote access to vector maps, remote sensing data, matrices, documents and spatial databases. There is supported a multilevel connection of servers among themselves for the distributed storage and processing of spatial data with automatic replication, backup and data protection. The program gives users the opportunity to make changes to geo-spatial data bases through the graphical interface of
