In the KB "Panorama", a GIS Constructor for Qt Designer SE version 15.0.3 has been developed. The program features updated libraries for programmable symbols, improved quality control of vector maps, and the ability to save vector maps in SHP format. The list of supported geospatial portals has been expanded.

The library of programmable symbols shape.iml64 has been updated. A symbol called "Polygon with proportional filling" has been developed. This symbol is designed for styling area structures with simple contours (without sub-objects). The symbol parameters include a description of the centerline, central vector symbol, and 4 area fill parts. When entering parameters for the 1st part, the conditional filling of half of the polygon is done, bounded by half of the contour (from the first to the center point) and the centerline. Entering parameters for the 2nd part fills the second half of the polygon. If there are parameters for the 3rd and/or 4th parts, filling is done with conditional quarters. The order of filling quarters corresponds to the order of parameters for the 4 parts, starting from the first point, considering the contour numbering direction. Contours with fewer than 5 or more than 255 points, or those with sub-objects, are filled according to the parameters of the 1st part.

Quality control of the vector map has been improved. When checking object overlaps with the sheet frame, a verification of points extending beyond the frame has been added. Aligning the contours of area and end points of linear objects has been unified into a single algorithm. Segments with points extending beyond the sheet frame are trimmed. Contour points located inside the sheet frame are extended to the frame at the nearest distance within the "Frame Exit Threshold" tolerance. Points within the "Frame Consistency Threshold" tolerance are considered extended (lying on the frame). The unified processing method helps minimize the likelihood of contour misalignment during point extension.

The task of saving a vector map in SHP format has been enhanced. When processing the attributes of map objects, the presence of repeating semantics is taken into account. The values of such semantics are concatenated into a string with a ";" delimiter and stored in a single field of the DBF table format. This allows for the correct display of repeated characteristics during further processing of the resulting files.

Support for opening geoservices portals from Rosreestr, the National Spatial Data Infrastructure, and the Federal Forestry Agency has been added. New layers have been connected to the Rosreestr geoservices portal - Thematic Maps. The following layers have been added: Cadastre Land Value, Land Categories, Types of Permitted Land Use.

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

The toolkit is adapted to work on a wide range of operating systems (Astra Linux SE, ALT Linux, Elbrus, Ubuntu, CentOS, QNX) and architectures (Intel, Elbrus, PowerPC, SPARC, ARM). The toolkit includes components for visual GIS application design and libraries of multi-platform multi-threaded GIS core. GIS Constructor provides a cross-platform MAPAPI interface, allowing the programmer to develop in their preferred operating system. Developers can release GIS applications for a set of operating systems by simply building with minimal changes to the program's source code.

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

The 11th international IT conference "Stachka" has concluded in Ulyanovsk. At this conference, specialists from KB "Panorama" presented two reports in the "GIS" section. The first report on import substitution in the GIS field, presented by Denis Vitcko, shared our company's accumulated experience and useful advice on implementing tasks for transitioning to GIS independent of imports, in accordance with Federal Law No. 491-FZ dated 04.08.2023.

The second report on the application of neural networks in digital cartography sparked lively interest among conference participants. In his report, PhD in Engineering Petr Sotnikov shed light on all areas of integrating artificial intelligence into GIS: from choosing a neural network to programming the server-side of geoservices, utilizing GPU capabilities, and frontend development. These reports are available on our website: "GIS Import Substitution" and "Artificial Cartographer: Image Decryption Service based on Neural Networks".

All reports from the 11th international IT conference "Stachka" are now available for viewing on the official event website. To access the reports, one needs to purchase an offline attendee ticket.

On September 27-28, "Stachka" will take place in St. Petersburg (COSMOS Pribaltiyskaya). A special 10% discount promo code "для_друзей10" is valid for purchasing recordings of all reports and all ticket categories for the conference in St. Petersburg. You can follow "Stachka" on social media platforms such as VKontakte and Telegram. KB "Panorama" looks forward to seeing you at the "Stachka" conference in St. Petersburg!

In the KB "Panorama," the "Workstation of the urban-planner" version 15.2.3 has been developed. The new version introduces the "Spatial Objects of the Urban Planning Information System" mode, expands the list of directories and classifiers of the information system, and implements a mechanism for synchronizing the attributes of spatial data sets with the semantics of the digital map classifier.

The registry "Spatial Objects of the Urban Planning Information System" is designed to maintain thematic sets of spatial data used in recording information in the urban planning activity support information system. The data sets include information on classes of spatial objects in vector model in relation to associated documents and attribute data. The structure of thematic data sets and the composition of used directories are implemented in accordance with the technical requirements for maintaining registers of state information systems supporting urban planning activities, as per the order of the Ministry of Construction and Housing and Utilities of the Russian Federation dated August 6, 2020, No. 433/pr.

Developed according to the order, the urban.v2.rsc classifier enables the creation of a multi-layer digital map and its application in preparing documents for urban planning zoning, territorial planning documents, creating consolidated plans of surface and underground communications and structures. The classifier systematizes code designations of capital construction objects, engineering infrastructure networks, electrical networks, communication networks, elements of layout structure, zones with special land use conditions, and lists features characterizing the properties of these objects. Each thematic data set contains its immutable set of attributes. Unified directories and classifiers of the information system supporting urban planning activities are used to systematize attributes. Object class attributes are synchronized with the semantics of the urban.v2.rsc classifier. To establish spatial-logical connections between documents recorded in the Urban Planning Information System and information with spatial map objects, an attribute "Spatial Data Class" has been added. This is a systematized group of data indicating belonging to a thematic data set. The new version of the program is available for download in the Download section.

Specialists from KB "Panorama" in collaboration with students from MIIGAiK have prepared a video lesson on working with the "Group of modes Point" and "Topology subpanel" modes. The educational material showcases the capabilities of point and object editing tools, as well as moving, deleting, and aligning objects. These modes are accessed from the "Map Editor" task panel and are available to users of GIS "Panorama", "Panorama-editor", GIS Panorama Mini, and other software products.

The video tutorial demonstrates methods of changing an object by editing its points: adding or removing points on an object; capturing a node or any point on a straight object; changing the direction from the starting point of the object to the endpoint, and other actions. It also illustrates ways to create copies of object sections, create intersection points, and align multiple objects. To access the educational materials, visit the "Video lessons" section.

Geoportal "Bank of spatial data" has been supplemented with a map of the Republic of Benin, 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".
