In KB "Panorama" the GIS Constructor for Qt Designer SE version 1 is developed for Windows. GIS Constructor for Windows allows you to develop GIS applications based on the MAPAPI interface, using the capabilities of the Qt framework for Windows. The program includes test cases demonstrating the basic capabilities of processing the digital data: display of digital vector, raster and matrix maps; printing of the displayed data to various output devices; search of objects of vector maps by the specified set of values of objects attributes and their geometrical parameters; creation and editing of vector maps; construction of three-dimensional models of terrain.
The components of the QDMapView map display are included into the graphics components. It can be taken as a basis for developing your own GIS application. Interactive interaction with the map can be realized through predefined event handlers. The functionality of changing the composition of the displayed data and objects, searching and marking, printing and other typical tasks is available through the dialogs and functions of libraries the GIS ToolKit for Windows.
GIS Constructor for Windows consists of components of visual and non-visual designing and kernel's libraries of GIS application from GIS Toolkit composition. Cross-platform of Qt libraries and MAPAPI interface allows you to carry out assemblage of the resulting source texts with help of GIS Constructor for Linux, while maintaining a single code base.
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 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.

In the new version, the tools for remote administration of the GIS Server on the Web are extended. There is added the ability to configure the GIS Server connection to other servers to gain access to remote data through several connections. Tools of monitoring a status of the server in Web are implemented for viewing the list of active users and open data, remote viewing the program work log.
There is improved the performance of updating vector data on clients with intensive updating of objects on the server (thousands of requests per second). The composition of diagnostic messages is expanded when updating the spatial database. Recording into the protocol of the server work is executed in UTF-8 encoding, the user interface is localized in several languages.

In KB "Panorama" a series of training materials on creating application tasks for GIS "Panorama" in the Microsoft Visual Studio environment was prepared. Lessons and the project of implementing an application with a complete source code will help understand the basics of working with the functions and methods of the PANAPI and MAPAPI interfaces. Users can familiarize themselves with the work of the application task by downloading and adding the corresponding library to the GIS "Panorama".
The first lesson outlines the general questions of creating a dll-library in the Microsoft Visual Studio environment, with the application code of the GIS "Panorama". Such questions as, the basic events and methods of the application task, creation of a toolbar are considered. From the second lesson you will learn how to create handlers for interactive modes of the application task, that is, those data processing modes that require the user to perform operations on the map, for example, selection by using the mouse of the objects or a certain part of the object. The third lesson describes the implementation of interactive modes that do not require the creation of a handler, for example, those in which interaction with the user occurs through dialog boxes. In the second and third lessons, examples of the use in the application task of various functions of the MAPAPI interface are presented.
