In KB "Panorama" the GIS Constructor for Qt Designer SE version 12.4.0 is developed. The new version includes service files for automatic processing of national coordinate systems and cartographical classifiers of a number of countries. For execution of import the user can use the test example included in the installation. For this purpose it is necessary to choose setting files and the directory with the data in the Shapefile format. The test example will automatically search for spatial data in the selected directory and create a map in national conventional symbols in the
In the new version of the GIS-applications kernel, the data display is optimized due to an improved mechanism of selecting the objects. Selection of objects on the map by means of visual components is improved. There is improved a convenience of working with standard dialogs that are part of the GIS Constructor.
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.
The new version of the program is available for download in the
