In KB "Panorama" the GIS Constructor for Qt Designer SE version 14.0.0 has been developed for operating systems Astra Linux SE (release "Smolensk"), Alt 8 SP, CentOS, Ubuntu. The new version of the toolkit makes it possible to implement direct connection to large spatial databases (millions of records) in the developed GIS applications using the DBM format support. Information from the database is displayed in the form of vector terrain maps. GIS application will be able to simultaneously edit the contents of databases connected directly and through the GIS Server, perform an exchange of information between different databases, agree the coordinates and attributes of objects in different databases, jointly display information from different databases in the form of graphic layers, combine data with images , matrixes of heights, vector maps and data from various geoportals and web services. Spatial information from the database is displayed in the form of cartographic conventional symbols, which makes the editing process transparent for the user. The set of displayed and editable objects and their semantic characteristics can be flexibly specified using an SQL query. For convenient customization of the database connection parameters, the database connection administration dialog has been implemented. User-defined settings are saved in a file with a DBM extension, which has a standard XML file structure. The set of dialogs for importing spatial data has been extended with KML and DXF formats. Thanks to the use of optimized and high-performance functions of the GIS core, the speed of import from exchange formats has been increased, which can be critical both for embedded devices that have limitations on processor performance, and for high-performance systems, where it is necessary to use the available processor power as efficiently as possible.

The initial opening of large vector maps, containing several million objects and more has been accelerated after importing data from exchange formats or databases - from tens of seconds to fractions of a second. There is improved a positioning of objects added onto a map in the display sequence chain, as when sorting a map. This improves the quality and ease of editing the map, speeds up the initial construction of the object tree when opening the datasets.

In the new version of the program, the transformation of vector maps into a given coordinate system has been accelerated by 4-6 times. The transformation process is called on the fly when the data of maps and geoportals in different coordinate systems are added into one window. When transforming on the fly, a copy of the input map is created in the map subdirectory with a name containing the name of the passport file and the current date.

Display of clusters used for grouping point conventional signs on a map has been improved. Into the cluster description the property "Display the first character in the cluster" has been added. Placing it in the position of the cluster sign will first display the first object in the cluster and then the cluster icon. In this case, the cluster icon can contain only the number of objects or other complementary elements of the conventional symbol. When drawing an object, various semantics can be taken into account, including links to graphic files, which makes the generalized sign more complex and informative.

Into the graphical component of connecting geoportals a support for layers from the Rosreestr geoportal has been added: Cadastral okrug, Cadastral districts, Cadastral quarters, Land plots, Land plots put up for auction, Red lines, Unified real estate complexes. Geoportal provides data in vector tile form in pbf (Protocolbuffer Binary Format) format. The data contains the coordinates of objects, signatures of plots, semantic characteristics.

The parameters of connection to geoportals can be flexibly configured for each user by editing the wmslist_ru.xml file.

When importing a set of maps sheets of SXF and TXF format, specified by the list in the DIR file, the ability has been provided for transfer of sheets by longitude on +/-360 degrees. It allows to duplicate the columns of sheets in the western and/or eastern hemisphere for expansion of dimensions of work region up to -360/+360 degrees. To duplicate sheets, copy the required file with a different name (for example, rename 01-12.sxf to 01-12_west.sxf) and change its nomenclature so that all sheets in the region have a unique designation (for example, rename 01-12 to 01-12_west ). Then, in a text editor, add a line with a new name sxf or txf into the DIR file and press the tab after the file name and enter the direction of transfer (for example, -360 or +360). The recalculation of coordinates and sheet passport will be performed automatically when importing the work region by the DIR file.

GIS Constructor is a set of geoinformation components for use in the visual programming environment of Qt Designer, which allows you to develop your own GIS applications. The visualization of the contents of digital maps is made in conventional symbols adopted for topographic, geographical and various special maps. Geoinformation system has ample opportunities for performing calculations, for providing display of spatial data on various graphic devices in standard and user systems of conventional symbols. The main functions can be executed in multithreaded mode. It supports automatic optimization of used memory for processing large amounts of data (tens of gigabytes) on limited resources (hundreds of megabytes).

The toolkit is adapted for 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 of visual designing the GIS applications and library of a multiplatform multithreaded GIS core. GIS Constructor provides a cross-platform MAPAPI interface that allows a programmer to implement development in an operating system convenient for it. The developer can release GIS applications for a set of operating systems by simple assembly with minimal changes to the program source code.

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

In KB "Panorama" the GIS "Panorama" version 14.0.1 has been developed. In the new version the tools for processing a photo and video data, point cloud data, digital mapping, display of sea maps, preparation of reports and others were updated.

In the task "Share your photos with the coordinates of the shooting", the dialog "The movement of the track (video)" has been improved. The algorithm for sequential display of video files in the selected folder with automatic transition from file to file has been improved. The program builds a set of tracks based on the metadata of video files. Tracks are formed in the form of linear objects with a four-dimensional metric containing three-dimensional GPS coordinates of the camera and the recording time of key frames of video files. In the new implementation of the program, the smoothness of video data playback has been increased. Synchronization of camera position on the map was improved. An information line has been added containing the name of the current video file, date and time of shooting. This tool allows you to quickly set the position of an object at any time provided by a set of video files.

The "Report Designer" task has been improved. Legend and explication maps are created in a conditional coordinate system, which eliminates distortion when added to a map created in a different projection. Maps with tables of legends and explication are created with a coordinate reference to the northeast corner of the designed map, which allows adding maps without additional positioning. In the Legend formation mode, the functions "Divide into blocks", "Split Block", "Combine blocks" have been added.

The number of lines with conventional symbols of objects in a block can be changed. A block on the map is created in the form of a grouping of objects by semantics, which allows further general movement, deletion and other group operations.

In the "Map Editor" task, the mode for creating objects the "Coordinate label" has been improved. There is added the ability to dynamically change the settings of the title, which is created onto the map next to the cursor. By right-clicking on the "Set font parameters" menu item, the font editing dialog is called up, in which you can change the color, height, name and other properties of the font. The new font values are stored in the object semantics the "Coordinate label". In the mode of Creating object by coordinates entered from the keyboard there is added a support for calculating the coordinates of a metric point using the specified initial coordinates of the point, azimuth and distance to the next point. In the Cut lists mode, the algorithm for cutting of objects specified by one list from objects specified by another list has been improved. When processing large amounts of data (hundreds of thousands of processed objects with thousands of internal contours), the operation time was reduced from several hours to minutes. The mode can be used, for example, for cutting islands in water bodies, glades in vegetation and for other objects. Processed objects are checked for self-intersections and automatically corrected. The contours of the cut objects are automatically matched to the processed objects, which significantly reduces the amount of manual work.

In the File menu, the task has been added for creating a work region by coordinates to form a work region by the specified dimensions or nomenclatures of topographic map sheets. The task is called using the main menu item "File/New/Work region by coordinates".

In the task of constructing labels by semantics of objects, the ability to apply arbitrary graphic labels not specified in the RSC classifier has been added. The choice of color, font, height, thickness and other parameters of the label is performed in the dialog, which is called by the button "Graphics". The location of the graphic label relative to the object being signed, filling and displaying the semantic characteristics is carried out according to the same algorithm as for the title from the map classifier. In the task "Control of label metrics" the ability has been added of processing the titles on the selected map or on all maps available for editing.

The task "Map Passport" has been improved. On the "Sheet Metadata" page there is added the information about execution of summary of the sides of a map sheet with adjacent sheets. The summary of adjacent map sheets is a coordination of areal and linear objects of adjacent sheets, the contours of which go onto the sheet frames. Objects of adjacent sheets are considered coordinated in case of conformity of the points going onto the frame, and absence of contradictions of semantic characteristics. By default, the signs of sheet sides summary have the "Not installed" value. When matching two adjacent sheets for the corresponding side in the passport of the map, the value "Completed" is set. For maps with an arbitrary territory without division into nomenclature sheets, the values "Not required" are entered in the summary fields. On the "Metadata" page, the list of metadata saved in the ".meta.xml" file has been expanded. There is added a recording an information about the restrictions on the use of the dataset: information about the agreement (contract), under which the dataset was created, containing restrictions on the distribution and use of data. Improvements were made in order to ensure the maintenance of federal and regional collections of spatial data and the completeness of the metadata description.

Displaying sea maps of S57/S52 standards has been improved. In the s57navy.rsc classifier for attributes that have a list of classified values (Attribute type: L - CATAIR, CATACH, ... TECSOU), property the "Repeat allowed" is set. When exporting and importing data, lists of attribute values (1,7,, 30) are written and read. For display of lists of values, into the combined title the new operating symbol ' r ' (#113.r) has been added, which allows to form a line from the list of attribute values, separating them with a space. There is refined a display of depth marks taking into account safety contours and taking into account depths on drying surfaces.

Algorithms for storing "point cloud" data in MTD datasets have been improved. Packing data, taking into account the area of the processed area and the specified storage accuracy, allows you to reduce the size of created MTD files by up to 4 times, which can be from several tens of Gigabytes to Terabytes. New algorithms improve the accuracy of terrain description over a larger area and accelerate the construction of 3D terrain models.

The task "Data list of map" has been improved. On the "Matrixes" bookmark in the context menu, a call of the new mode "Change of location of a matrix on dx/dy meters" has been added. The mode is intended for changing the binding of matrixes of height, layers and qualities of the document onto a specified value in meters. The processed matrixes must be available for editing. Changing the location is carried out both for one and for all matrixes of the document.

The "Display/Inform window" item has been added into the Options menu to enable or disable a pop-up message that informs the operator about the result of the action performed in the map window.

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

In KB "Panorama" a digital geographic map of scale 1: 1 000 000 in format SXF onto territory of the Republic of Estonia has been prepared. As a source for preparation of the map the VMap0 data obtained from the information from the site www.gis-lab.info has served. The map contains information on the number of inhabitants for cities and the name of settlements in Russian. As additional materials the World map of scale 1: 5 000 000 and OpenStreetMap data were used.

The map was led to the classifier of geographic maps of scale 1: 1 000 000 (1mogk13g.rsc). It can be used for a general assessment of the area and the study of natural conditions, to ensure the educational process, as a basis for the creation of geographic maps of a smaller scale, thematic and special maps, and solving other tasks. The map is distributed free of charge under a free license.

Digital geographic map of scale 1: 1 000 000 in SXF format is available for download on the page "Digital maps".

In KB "Panorama" the "Complex of 3D analysis" version 6.1.0 for a GIS"Panorama" 14 has been developed. The complex is intended for creation of surfaces models and solving the problems of spatial analysis with use of the constructed models. In the new version the tools of three-dimensional modelling, import and export of spatial data were updated.

The task "Import of MTD-model from LAS-file" has been improved. The task carries out loading of MTD-models from LAS-files obtained by means of LIDAR (light detection and ranging) laser locators. The data of LAS-files can contain results of sounding of the earth or sea surface, atmosphere. The MTD-model contains the dot measurements sorted by tile that provides fast access to data for solving computational and analytical problems. The new mode of block filling of MTD-model reduces time of loading LAS-files in volume more than 8 GB by 3-5 times. Loading of control file LAS with 555 million points in volume of 14.4 GB is executed in 16 minutes.

The list of supported formats of data for export of a matrix of heights has been expanded - TXT, TIFF, KMZ. The formed KMZ archive contains the KML (Keyhole Markup Language) project file and a set of pyramid tiles for the saved territory. The KML file contains a description of the matrix data parameters: the names and coordinates of the matrix binding, as well as the priority of their display.

The task of creating a three-dimensional terrain map has been improved. Possibility of saving the model into DB3D format has been added. DB3D format is intended for storing and displaying pyramids of three-dimensional tiles packed together with metadata tables in SQLite format. It provides fast tile-based output of spatial information in accordance with the requested scale and territory. The volumetric tile matrix is of type GoogleCrs84Quad. Level of scaled texture detail of data and the coverage area are not limited. Surface textures are stored in JPEG and PNG formats. Saving a terrain model to the database accelerates the display of a three-dimensional terrain model in desktop and Web-applications, makes it possible to work with the model later without the initial cartographical data.

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

Specialists of KB "Panorama" prepared and placed the map of the Yamalo-Nenets Autonomous Okrug on the geoportal "Bank of spatial data". The map was formed using OpenStreetMap data, source data was obtained from Geofabrik website. 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) and was saved into a packed project (mptz). The MPTZ format project includes a digital map of the region's territory (country, subject of the federation, administrative region), a map of the administrative-territorial division of the region and a digital classifier. 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".
