The KB "Panorama" has developed GIS Constructor for Qt Designer version 15.0.3 for the MS Windows operating system. The program has improved algorithms for data processing and display, refined the task of connecting to geoportals, and expanded the functionality and list of available methods in the MAPAPI interface.

In the new version, the number of supported sheets for multi-sheet maps has increased fourfold. The accuracy of transparency calculations for vector objects and polygon objects — colored glass — has been enhanced. Algorithms for interaction with the GIS Server have been improved, including the mechanism for interacting during the editing of maps containing a small number of objects. The rendering of height and depth matrices has been accelerated with smoothing. The display of smoothed matrices has been parallelized, significantly reducing delays when working with them. For example, on a quad-core processor with a clock speed of 3.5 GHz, the rendering speed of smoothed matrices has increased by 2.5 times.

The capabilities for displaying vector maps have been enhanced. The rendering of dashed lines has been optimized for drawing long segments at large map scales. The new functionality for automatic generalization of displayed map objects allows polygons and linear objects to be visualized as clusters when their dimensions become smaller than 48 pixels during scale changes. These new display capabilities enhance the visibility of vector maps without losing informativeness.

The program has increased the speed of loading and displaying tiles thanks to automatic performance assessment of the computer and multithreading. Access to archived geoportal data has been added, enabling queries based on date, period, and cloud cover of images. Caching functions for the WMS protocol have been introduced to speed up access and ensure offline operation. Support for dynamic geoportals and proxies with authorization has been implemented. New geoportals and layers have been added, including data from Roskadastr and a new service "Topographic maps of the world". The ability to connect digital terrain models via the WCS protocol has also been realized.

The tools for adding data to the main document now support graphic file formats BMP, JPEG, PNG, GeoTIFF, and TIFF.

For the object list, functions for opening the object list file for data from the GIS Server and adding map objects to the list based on search context have been implemented. The capability for pan-chromatic merging of rasters has been realized. This allows for the enhancement of the resolution of a color raster using a higher-resolution pan-chromatic image. Multispectral data often contains a higher-resolution pan-chromatic channel, and merging it can improve the visual characteristics of the color raster. Merging can be performed in one of three ways: averaging by channels, transforming through the IHS color space, and using the Brovey method.

Methods for editing label text have been added, including options for setting text in sub-objects with line breaks, fitting text to the dimensions of a rectangular area, and establishing overall text alignment. An MTW to TIFF export function has been implemented, allowing the setting of height format, algorithm, compression level, tile size, pseudocode value, and other parameters. Methods for displaying selected object lists with custom styles (defined by conditional symbols) in the open document have been added. This enables users to group objects into lists and assign each list its own display style. Custom styles consist of a set of conditional symbols based on localizations.

Methods for constructing intersections of multipolygons as multipolygons and creating map objects from coordinates in a text file have been realized. Support for the WebP format, used for image compression in Mbtiles, BIR, GeoPackage databases, and geoportals, has been added. Import functions for DXF have been refined to support various code pages for correct processing of map labels. Algorithms for reading spatial data from the DBM format have been improved. Diagnostics for connecting to spatial data databases have been expanded, particularly for authorization errors. The saving of vector maps in SHP format has been optimized to account for repeating semantics, which are now combined into a single field in the DBF table. An API interface for auto-saving a full copy of the map during editing has been implemented.

GIS Constructor is a set of geoinformation components for use in the visual programming environment Qt Designer, enabling the development of custom GIS applications. Visualization of digital map content is carried out using conditional symbols accepted for topographic, general geographic, and various special maps. The geoinformation system offers extensive capabilities for performing calculations and ensuring the display of spatial data on various graphic devices in standard and custom symbol systems. Core functions can be executed in multithreaded mode. Automatic optimization of used RAM is supported for processing large volumes of data (tens of gigabytes) on limited resources (hundreds of megabytes).

The toolkit is adapted for operation on a wide range of operating systems (Astra Linux SE, ALT Linux, Elbrus, Ubuntu, CentOS, QNX, MS Windows) and architectures (Intel, Elbrus, PowerPC, SPARC, ARM). The toolkit includes components for visual design of GIS applications and libraries for a cross-platform multithreaded GIS core. GIS Constructor provides a cross-platform MAPAPI interface, allowing developers to work in their preferred operating system. Developers can release GIS applications for a set of operating systems through simple builds with minimal changes to the source code.

The new version of the program is available for download in the Download section.

Specialists from the "Panorama" Design Bureau have created a video tutorial on using the "Formation of a combined symbol" mode. This mode is part of the "Map Editor" toolbar and is available to users of the GIS "Panorama" and "Panorama-Editor".

The task "Formation of a combined symbol" is used for placing conditional combined symbols on the map. A combined symbol is a group of vector symbols that share a common anchor point and are arranged vertically. It is not recommended to use vector objects that are displayed as "Graphic Symbols".

The video tutorial demonstrates the process of creating a combined conditional symbol consisting of two vector objects. The dialog window for this mode is divided into two parts. The lower field contains a template ruler that allows users to pre-select conditional symbols as components of the combined symbol for future use. The composition of the conditional symbol layouts is saved during the creation of the vector map with the selected classifier.

In the upper field of the dialog, there is an option to select a conditional symbol from the classifier without adding it to the template ruler. Additionally, users can modify the attribute data of conditional symbols using the "Semantics" button and change the arrangement of the symbol's components. When placed on the map, the combined symbol is automatically grouped into a set of objects. If there are multiple open maps in the document, after activating the mode, users should select the map where the combined conditional symbol will be placed.

You can find the training materials in the "Video Lessons" section.

In the KB "Panorama," version 15.3.2 of the "Workstation of cadastral engineer" has been developed. The new version has improved tools for generating cadastral documents and the Cadastral Work Database. The "Land survey plan" mode has been updated to version 9. It now includes the generation of a text report and XML document for the formation or clarification of a part of a land plot. For this type of cadastral work, an algorithm has been implemented to search and extract data from the cadastral map using the boundaries of the existing land plot. The program automatically searches for all parts within the object with the code of the existing plot and inserts information about them into the report.

The procedure for processing multi-contour parts of land plots when generating text reports has been refined. For each part, one table is inserted, separated by a blank line for information about several contours of the part, similar to multi-contour plots. When filling out the section "Clarification of Boundaries of Adjacent Plots", consideration is given to the contour type of the adjacent plot, processing only the plots being clarified.

Due to the extension of the validity period of the XML schema MP_v09_R03, established in Rosreestr letter No. 18-6325-TG/24 dated July 8, 2024, elements related to version MP_v09_R04 have been temporarily removed from the dialog. The path to the schema for verification has also been changed in accordance with version MP_v09_R03. A variable algorithm for searching characteristic points of cadastral objects has been implemented to establish their belonging to a cadastral object. When forming plots, it is permissible to omit checks for cadastral and accounting numbers for point markers.

The dialog "Information from the state real estate cadastre" has been updated. Tabs that were not supported by information have been removed, and the order of sending requests has been modified based on the type of cadastral object. An analysis of the area type of the cadastral object—whether clarified or declarative—has been added. Information about the signature type is displayed in the dialog.

The "Base of cadastral works" mode has been enhanced, adding the ability to attach files in XML and ZIP formats to documents. A new button, "Add with Copying", has been added to the main form of the mode, allowing users to add new list items by copying information from existing records in the database. This approach enables the same foundational document to be used when creating multiple different cadastral documents.

The "Editing attributes of a cadastral object" dialog has been updated. The outdated field "Presence of real estate object" has been removed from the display of information about parts of land plots, and several field names have been changed. For land plots, the order of semantic display has been altered. When processing a multi-contour cadastral object "Part", the value from the "Contour number of the part object" field is recorded in the first column of the "Contour List" table; otherwise, the value is taken from the "Cadastral or other number or designation" field. Attributes characterizing information about the zone have been grouped together for easier input and editing.

The "Technical plan" mode has been improved, fixing the saving of region codes into semantics and internal code arrays, as well as displaying the region name obtained from the "Address database" in the dialog. If a region code is present, the object's address is recorded in the XML file. The algorithm for searching plots within which a structure is located has been modified. Report templates have been corrected to eliminate duplication of the text "The technical plan was prepared as a result of cadastral work related to:"

The "Map (plan) of the object land 2024" mode has been updated, correcting the recording of contour numbers (designations) for multi-contour objects in XML. The saving of attached documents defining land categories, types of permitted use, and plot addresses for reuse has been implemented. The recording of the oks_exploitation element in the XML file has been corrected.

The "Correction of registry errors" mode has been refined. The check for the presence of an original contour for the corrected object has been changed. This algorithm ensures the processing of cadastral objects that previously did not have coordinate descriptions of boundaries. In this case, only corrected coordinates are recorded in the XML file, without the originals.

The "Certificate of inspection of the property" mode has been enhanced with a check for the presence of an attached file when recording documents. If the file exists, an optional element AppliedFile is recorded in the XML document. If there is no file, the element is not created.

The new version of the program is available for download in the Download section.

The Design Bureau "Panorama" has developed GIS "Panorama" version 15.3.2 and the automatic recognition and vectorization service "Panorama Vision" version 1.1.0. The new version expands the capabilities of the "Panorama Vision" automatic recognition and vectorization complex and improves the tools for automatic interpretation of satellite images. The program includes a neural network model for outlining buildings in terrain images. The "Panorama Vision" service converts recognized building outlines into rectangular shapes and adjusts their positions to accurately match the foundations of the buildings. The resulting model ensures recognition accuracy of over 90%. To train the model, satellite images of cities in the Russian Federation were used alongside vector maps containing outlines of roofs and walls of buildings. For precise outline determination, the spatial resolution of the data must be between 0.5 to 1 meter/pixel for satellite images and 0.25 to 0.01 meters/pixel for aerial photographs. For example, recognizing building outlines in satellite images of Moscow with a resolution of 0.6 meters/pixel over an area of 25 square kilometers took 2 minutes and 20 seconds. As a result of the processing, 2,895 objects were created. The application of the new model will allow for identifying unregistered buildings and structures in conjunction with data from the Russian State Register, as well as promptly updating existing information on vector maps.

The complex allows for processing terrain images in RSW/JPG/TIFF/PNG formats and data from open geoportals. "Panorama Vision" recognizes outlines of fields, hydrological objects (rivers, ponds, lakes, etc.), buildings, and structures. The processing results are provided to users in the form of a vector map, which can be downloaded via the WFS protocol. The complex is implemented as services that provide remote access to data interpretation. It is hosted on the internet on the servers of the design bureau "Panorama". Access to the complex is available from the list of application tasks in GIS "Panorama": Launch applications - Automatic sattelite recognition.

The new version of the program and documentation are available on the website in the Download section.
