On August 8, 2019, a seminar "Land Management, surveying, GIS - European legislation and technologies" was held in the city of Yantarny in the Kaliningrad region. The event was organized by the private educational institution of additional professional education
At the seminar, the specialists of KB Panorama gave lectures on the topics "Basic legislative initiatives in the field of geodesy and cartography in European countries", "Instruments used in the performance of geodetic works, methods of work, including using UAVs, coordinate systems", "Geoinformation systems used in land use and in geodetic work." The course participants were employees of the
You can familiarize yourself with the presentation and report presented at the seminar on the website in the Presentation section.

The map was led to the modernised classifier of large-scale plans of scale 1: 5 000 (map5000m.rsc).
Publishing of updates in bank of spatial data is made by using the program of
Publishing contents of bank of spatial data on the geoportal and data access for downloading are implemented by means of
Free maps on the basis of OpenStreetMap data are available for download on the page "Digital maps and images".
In KB "Panorama" the GIS Constructor for Qt Designer SE version 12.6.0 was developed for the real-time operating system (RTOS) QNX Neutrino 6.5.0. The program implements the development functionality of GIS applications supplied for OS Astra Linux, Ubuntu and other Linux systems. Due to the cross-platform interface of working with digital maps MAPAPI and Qt framework libraries, GIS applications can be developed in a desktop Linux-system. After implementing the necessary functionality, an assemblage of GIS application for a target QNX-platform will require a minimum of changes in the source code of the program.
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 the used RAM for processing large amounts of data (tens of gigabytes) on limited resources (hundreds of megabytes).
The toolkit is adapted to work on a wide range of platforms and supports operating systems such as Astra Linux SE, MSVS, CRTOS "Neutrino", "Elbrus", "Zarya", Ubuntu, Alt Linux, QNX, CentOS and others. It can be used in computer complexes with processors of architectures ARMv7, Elbrus, PowerPC, Intel x86, Intel x64 and others.
The microkernel architecture of the RTOS QNX Neutrino allows you to scale the program code in accordance with the requirements of very compact embedded systems with minimal resources, and at the same time the RTOS QNX Neutrino is powerful enough to work as a desktop OS. From the point of view of developers, system administrators, users, the valuable qualities of QNX Neutrino RTOS are also that it is based on the POSIX standard, provides high real-time response speed (due to the possibility of limiting the maximum amount of non-reentrant code) and has a fault-tolerant microkernel.
Specialists of KB "Panorama" prepared the video lesson
The training material acquaints users with the task "Check of absolute elevations" intended for control of objects elevations and values of the isobaths depths of a sheet of a vector map. For the analysis of results of working the task of control the program "View error" is used, which is available for launching from the "Map Editor" panel. The dialog "Matrix builder" is called from auxiliary panel the "Calculation and building by matrix of heights" of the task "Map Computer". For a more visual display of the terrain, a three-dimensional model is built in the "Navigator 3D" task. This will allow you to visually assess the topography and conduct a preliminary analysis of a specified territory. The task "Modify matrix projection" is available from the section "Processing of elevation matrixes" of the panel "Run applications". With its help it is possible to change a type of projection, parameters of a projection, spheroid and a datum.
Previously the video lessons of this series were published:

In KB "Panorama" the
For semantics of type the link to a file there is added the ability to select a folder. When referring to the semantics value, the dialog for selecting a file from this folder for viewing will be called. For files of zip type, a list of files compressed in the archive is displayed with automatic decompression and display of the selected file.
To simplify the preparation of reports in the "View Passport" dialog, there is added the ability of a map creation by a format of standard printed page with mapping of a frame of the print area in the form of graphic object. The frame of the print area is formed in accordance with the specified indents for the print area. To form a map by page format, select the menu item New\Plan and in the dialog enable property the "Frame by page size". When generating a report, the insets, documents, labels and other elements can be put to the created plan.
In the "Map Print" dialog box, the automatic setting of the parameters of the current printer has been added with the setting of the paper size and the printable area corresponding to the created plan.
There is added the ability to display insets under the vector maps, which simplifies the preparation of reports against the background of map fragments, images and other types of data that are connected as insets. The mode "Create object" of the task "Map Editor" has been improved. When creating an object using the "Arbitrary contour" mode for linear, polygonal and vector objects, the ability of dynamic entering the length of a segment is added. In the menu Options\Coordinate System\Geodetic (World WGS 1984 spheroid) the item "Degrees, Minutes" has been added to display the coordinate view, as in a number of applications for smartphones.
Dialogs for editing conventional symbols of objects are improved. There are added the buttons for copying from one object and inserting into another one of any conventional symbol through the clipboard. A new type of conventional symbol is added: shift line of type the "Color glass". For lines of the type "Set of elements", the ability is added to change the color of all line elements simultaneously and swap the elements. Into dialog of editing a vector symbol the additional marking with the center in a point of a binding is added, which allows you to speed up the process of creating and editing of images of vector symbols.
The new version of the program is available for download in the
