In KB "Panorama" the GIS Constructor for Qt Designer SE version 13.3.0 has been developed for operating systems CentOS, Ubuntu, Astra Linux SE. In the new version, the functionality of the component of displaying three-dimensional model has been improved. When importing models into the DB3D format, spatial data TLS, OC3, DAE, OBJ can be imported as a set, assembled from various catalogs, with the ability to interactively select the composition of files. Possibility has been added for selecting a coordinate system of a binding the imported model: from the list, from a file of the metadata and EPSG database. For the COLLADA (DAE) format, a loading of the data can be executed in one of several provided modes depending on a way of the geometry analysis. For each level of the model, the user can select an individual texture value. In the component for importing graphic files when processing BMP, PNG, JPEG, TIFF, GeoTIFF, IMG formats, the user is provided with extended information about the source file: data type, minimum and maximum channel data values, interpretation method, projection parameters and coordinate systems. To optimize the import of large graphic files, it is possible to create an output file without copying data, in this case, raster data will be read directly from the original graphic file. To improve import performance, the user can disable transaction logging. In the dialog of importing matrixes from the SRTM, GeoTIFF, IMG formats, the ability to eliminate undefined heights by mode of linear interpolation of neighboring known values has been added.
Operator.p3d library of three-dimensional symbols of operator.rsc classifier has been improved. There are added the simplified models of Russian military equipment for displaying at distances far from the observer. This approach increases the speed of displaying a three-dimensional terrain model on maps of the operational situation with a large amount of equipment. Thus the nearest view of models remains detailed, corresponding to specific types of weapons. The operator.rsc classifier provides preparation of special maps for all types and branches of the RF Armed Forces.
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 map was led to the modernised classifier of large-scale plans of scale 1: 5 000 (map5000m.rsc) 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

In this version a new installer of the GIS ToolKit is presented, in which an automatic customization of paths to GIS core libraries, source codes, setting of Windows environment variables have been added. The new installer, through the use of automatic settings, greatly simplifies the process of installing the GIS ToolKit into the palette of development environment components.
The GIS ToolKit consists of a set of visual components (supplied in source code) and API functions of the GIS core for direct access to spatial data. The toolkit is intended for the development of client-server and desktop 32-bit and 64-bit applications that require processing and visualization of spatial data. Spatial data can be located both at the workplace (direct access to data) and in the local network or the Internet (components of access to the

Geoportal "Ecuador" provides information on the political and administrative division of the country (as of 2017). Information about the territorial structure of the state is presented in the form of maps and a short text description for each administrative unit. As a cartographical basis, the map of Ecuador at the scale of 1: 1 000 000 and the scheme of organizing the territory at level of provinces and cantons are used.

The values of the cells of the resulting matrix are calculated based on an expression, which can consist of various mathematical and logical operations. You can also use one or more conditional operators in an expression, which allow you to change the values of cells depending on the fulfillment of specified conditions. An important feature is the ability to check cells for presence of data and the ability to set cells to NULL (no value).
An example of the work of the matrix calculator can be the following task. A factory and a motorway are sources of pollution. It is necessary to build a matrix showing the areas in which the total pollution exceeds the maximum allowable rate for residential buildings, recreational areas and social facilities. As the initial data there are the matrixes reflecting levels of pollution from factory and a motorway, and also a matrix containing maximum permissible levels of pollution. The solution to such a problem will be a matrix built on the basis of the following expression: Con ("1.pollution_factory.mtq" + "2.pollution_road.mtq"> "3.mpc_value.mtq"; "1.pollution_factory.mtq" + "2.pollution_road .mtq "; setNull), which means that if the sum of pollution from the factory and the motorway is greater than the maximum permissible concentration, then this sum is written into the matrix cell, otherwise - NULL.
"Complex of 3D analysis" is intended for creating models of surfaces and solving the problems of spatial analysis with their use. A surface model can display such terrain properties as elevation, pollution concentration, precipitation, radiation levels, and others. Models of surfaces can be created according to data of a vector map, by the information from database tables, and also can be loaded from external formats (SRTM, GeoTIFF, LAS and others, more than 20 in total). Models of surfaces are used for formation of a three-dimensional terrain map, and also when solving problems of the analysis: calculation of distances, areas and volumes, profiling, construction of visibility zones, determining the directions of slopes, obtaining other derived surfaces.
