New possibilities are added for processing rasters that open directly without conversion to RSW (when open, the mode "Do not copy the source image to the RSW file" is selected). There is added joint discovery and display of Landsat, Kompsat and GeoEye images supplied as a set of single-channel TIF rasters. Single-channel TIF rasters are interpreted as different channels of the same image. The restriction on the maximum size of survey images of 4 GB is removed, which allows processing images of any size. The GDAL library has been updated to version 2.2.0, in which new formats of processed rasters are added.
The task of connecting geoportals has been improved. Possibility is added for scaling the image from the previous level if the data at the subsequent levels are not present. In order to improve the security of information exchange with geoportals, the ability to connect data via https is added. Support for these protocols will improve the protection against attacks based on listening to a network connection.
The task "Loading data from the COLLADA format (* .dae)" has been completed to edit the 3D view of the object in the classifier editor. A new format has been developed for storing data in the SQLite database in the form of tiles that are convenient for displaying in web applications. Processing of nested nodes with links is added.
In the task "Automated generalization of topographic maps" the new mode "Setting the boundaries of rivers visibility" is added. The mode "Setting the boundaries of rivers visibility" is intended for simplification of a hydrographic network in the map scales 50 000 and 100 000. The goal of simplifying the hydrographic network is to assign specific ranges of visibility to specific objects of the hydrographic network, corresponding to their importance. Degree of the rivers importance is defined by the length and character of its location relative to other rivers.
In the complex of geodetic tasks, a new algorithm for generating reports on the metric and semantics of objects has been developed, which implements the functions of the report generator. The universal report generator works as a software wizard that performs the following procedures: customizing the schema and report parameters; automatic creation of scheme of the object; schema display and its interactive editing; filling the report on the beforehand prepared template.
At requesting lengths of objects or segments having a length of more than 5 degrees in longitude, the orthodrome is automatically constructed, which ensures the calculation with the accuracy of class 1 triangulation. Accurate length calculations are performed if the "Precise square and length" property is set in the "Options" menu.
The dialog "Data List of map" and the task "Map legend" have been improved. Multichannel images the Landsat, Kompsat and GeoEye, supplied as a set of single-channel TIF rasters, are displayed in the list of rasters as a node containing a complete list of used TIF files.

In KB "Panorama" the GIS Constructor of version 12.1.0 is developed for operating system Astra Linux Special Edition (Release "Smolensk"). The new version combines the possibilities of developing the GIS-applications for Qt tools of version 4 and version 5. Using only one software product, the GIS Constructor user can create a GIS application for the required version of the Qt framework, with a minimum of effort.
The developer can easily switch the used version of the Qt framework using a command-line utility with a simple interface. With its help, you can get information about the used version in one action and change it to the desired one. After that, the GIS Constructor is fully ready to work with the selected libraries of Qt toolkit. For the convenience of the system administrator, the installer of GIS Constructor automatically performs the initial configuration of the application in the automatic mode. To determine the used version of the Qt framework, the current environment of the operating system is analyzed.
Universality of MAPAPI interface and GIS Constructor components provides portability of the developed source codes. The developer, depending on the task to be solved, can easily reassemble the GIS application for the required version of the Qt toolkit and create an image of the product for the end user.
The new version has expanded the possibilities of interacting with processing, which require significant resources of computational time. Using the modified callback interface, the developer can receive information about the progress of the processing and interact with the process in an interactive manner.
The display of operational signs, as well as programmable conventional signs of general purpose has been improved. The interface for creating temporary user maps has been expanded. Now the developer can directly specify the location of the created files by specifying a special environment variable.
GIS Constructor implements support for a single geoinformation space managed by spatial data servers (GIS Server) and application servers (
Due to the ability to connect to the GIS Server, users of GIS applications can directly connect to geospatial data bases, view and edit tables in the form of maps in the specified conventional symbols. Support of interaction with GIS WebServiсe SE allows to get access to the spatial data by the international standards OGC WMS, WMTS.
GIS Constructor is a set of components for developing GIS applications for use in the visual programming environment of Qt Designer. Visualization of the contents of digital maps is made in conventional symbols adopted for topographic, geographic, cadastral and other types of maps. Geoinformation system has wide possibilities for creation (addition) of the user conventional symbols, supports the various coordinate systems and projections.

For request of creation of buffer zones the possibility of their construction is implemented by the closed linear objects, and also by an arbitrary object passed through the input file gml. The new request is added of obtaining distance, azimuth and direction angle.
For construction of geo-covers in the
In the program analytical possibilities of requests of the transactions are improved, allowing to analyze the list of available for object of editing of semantic characteristics and to update only transferred for semantics change.
GIS WebServiсe SE supports all international standards (OGC WFS, WFS-T, WMS, WMTS, WCS) with which help the transfer and display of spatial data is carried out. The program provides the ability to issue tiles for any user or local coordinate system. The application is implemented on Windows and Linux platforms, is compatible with Apache, IIS and nginx web servers.
