Geoportal "Bank of spatial data" has been supplemented with a map of the Islamic Republic of Pakistan, formed according to OpenStreetMap data. To work with the map, you can use the GIS Panorama Mini program or other software products of KB "Panorama".

The map was led to the modernised classifier of large-scale plans of scale 1: 5 000 (map5000m). Publishing of updates in bank of spatial data is made by using the program of Databank of digital maps and remote sensing data.

Publishing contents of bank of spatial data on the geoportal and data access for downloading are implemented by means of GIS WebServer SE.

Free maps on the basis of OpenStreetMap data are available for download on the page "Digital maps".

In the KB "Panorama", the Database of digital maps and remote sensing data version 8.8.0 has been developed. In the new version, a separate start page has been added for quick and convenient access to different sections of the complex. The page is implemented in the form of "tiles", leading to specific sections or tasks. The list of available sections is determined by the rights of each user working with the system.

The ability for users to register independently has been added. Upon self-registration, users are placed in a group with minimal access rights. Changes to access rights are made by the system administrator.

In the new version, downloading large datasets has been optimized. The process of creating a data archive is visually displayed, and upon completion, the download is initiated. If errors occur, a message is displayed and recorded in the event log. The logging during application processing and data loading has been expanded.

Data security is ensured by restricting access rights based on security features included in the operating system. Standard authentication, digest authentication, system authentication (using web server tools), and domain authentication (Kerberos or ActiveDirectory) are supported. Additional security is provided through end-to-end authentication when working with the database. Connection to the database occurs with the rights of the user working with the system. The complex is adapted for operation on a wide range of operating systems (Astra Linux SE, ALT Linux, Elbrus, Ubuntu, CentOS, MS Windows, and others) and architectures (Intel, Elbrus, Baikal). The program is registered in the registry of domestic software under number 1862.

The database of digital maps and remote sensing data serves as the foundation for building spatial data infrastructure at federal, regional, and municipal levels within corporate information systems. Within a unified geoinformation space, the database implements the collection, storage, quality control, search, and provision of spatial data in exchange formats. Spatial data selected using the program can be made available for multi-user access on the GIS Server and published according to international standards OGC WFS, WFS-T, WMS, WMTS, WCS on the GIS WebService SE application server. Users can access the data both from a thin client (using GIS WebServer SE) and from desktop applications (GIS "Panorama", GIS "Operator"). The database of digital maps and remote sensing data facilitates the creation of a cloud storage for spatial data, providing access to this data and automated generation and updating of geocoverages.

Automated collection and generation of metadata are carried out according to the standards ISO 19115:2003, Geographic information — Metadata, and ISO/TS 19139, Geographic information — Metadata — XML schema implementation. Reduced copies of data images are automatically generated, file checksums are verified, and the completeness of datasets is checked. The placement of spatial data in the file storage is done with integrity verification, control of structure and content of the data. The results of the work are logged and entered into the metadata database. Automatic backup of metadata and spatial data storage is provided with integrity control and data recovery. A multilingual interface is supported.

The "Spatial Data Bank" portal demonstrates capabilities for organizing the storage, accounting, and issuance of vector maps, remote sensing data, height matrices, and terrain models. The portal contains vector maps in SXF format, created based on data from open sources (OpenStreetMap, VMap0). The spatial data includes maps of Russian Federation subjects, countries, and cities both near and far abroad. In total, there are over 400 vector maps and 6,700 raster datasets with a total volume of more than 230 GB. Specialists from the "Panorama" KB update and maintain the information on the portal weekly. All published data is distributed free of charge under a free license.

The new version of the program is available for download on the Download page.

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.

From September 16 to 19, 2024, a joint international scientific and technical conference titled "Digital Reality: Space and Spatial Data, Processing Technologies" will take place in Minsk, Republic of Belarus. The event is organized by JSC "Racurs", the State Corporation "Roscosmos", the State Property Committee of the Republic of Belarus, and the National Academy of Sciences of Belarus. Representatives from the KB "Panorama" will give presentations on topics such as "Artificial intelligence in cartography", "Formation of a unified geoinformation space", "Spatial data. A new digital reality", and "Experience in Supporting the Federal Fund for Spatial Data, the Regional GIS of the Ryazan Region, and Corporate GIS". During the event, company specialists will share best practices in using geoinformation technologies to enhance business efficiency and innovative methods of their application.

The international conference in Minsk will facilitate the formation of new professional connections among market participants, allowing for the exchange of experiences, regional practices, and advanced solutions in photogrammetry, geodesy, cartography, and geoinformatics. Joint discussions among experts will provide opportunities to develop effective directions for industry growth in the coming years. We invite everyone interested to attend the conference and participate. Detailed information about the upcoming event is available on the official website.

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.
