The complex of conducting the regional geoportal "Geoportal Region" ensures the collection, processing and analysis of spatial data in the interests of the information system for managing the socio-economic development of the region. This allows you to make weighed and informed decisions in various types of activities: urban planning, cadastre, agriculture, transport, ecology, healthcare and others. A specialized regional geoportal is being built using serial domestic software from KB "Panorama". GIS "Panorama" provides employees of various departments with functionality for preparing digital maps, which are subsequently placed on a spatial data server managed by GIS Server SE. The spatial data service GIS WebService SE ensures the publication of materials on a regional geoportal under the control of GIS WebServer SE. For the convenience of users, industry data layers are grouped into industry projects, access to which is determined by role and rights.
GIS Constructor for Qt Designer SE 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 complex for maintaining the regional geoportal "Geoportal Region" and the GIS Constructor for Qt Designer SE are included in the Register of Domestic Software and are certified in the information security certification system for information security requirements for processing information classified as "secret".

Connection of spatial data in Mbtiles, BIR, GeoPackage formats has been improved. The new version adds support for the WebP format, used to compress images in Mbtiles, BIR, GeoPackage databases and geoportals. The Webp format allows both lossy and lossless image compression. The format is based on algorithm of compression of the still image (key frame) from the VP8 video codec. Uses a RIFF container for storage. On average, it compresses images 40% more efficiently than the JPEG format. It is widely used for transmitting data and images in geoportals. Due to its smaller volume, it allows to accelerate data transfer. The task of connecting geoportals has been improved. There is added a new geoportal - Topographic maps of the world.
Drawing matrixes of heights and depths with smoothing has been accelerated. The display of smoothed matrixes is decomposed into threads, which significantly reduces delays when working with them. For example, on a 4-core processor with a clock frequency of 3.5 GHz, the speed of displaying the smoothed matrix increased by 2.5 times.
Possibility of connecting digital terrain models via the WCS protocol has been added. Connection to WСS-сервису is carried out on the basis of standards the OGC 09-110r4 Web Coverage Service. At the same time, data from any number of WCS services can be opened together with data from geoportals, data from GIS Servers, and locally open data. To increase the speed of working with the WCS service, data caching is supported on the client. The information received from the service allows you to create 3D terrain models onto an area of any size, up to the surface of the entire Globe.
The list of available MAPAPI methods has been expanded. The list of methods for editing signature text includes methods for setting text into a subobject with division into lines, adjusting text to the size of a rectangular area, and setting general text alignment. Function of exporting MTW into TIFF has been implemented, allowing to set a height format, algorithm and level of compression, sizes of a tile, value of a pseudo-code and other parameters. Methods have been added for displaying selected lists of objects with custom styles (specified conventional signs) in the open document. It allows the user to group objects into lists and to set own style of display to each list. Custom styles are a set of conventional signs by localizations.

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 line of sign editing tools contains modes for creating and editing sign elements and inscriptions. In it the possibility of loading a file of the image in formats png, jpg, ico, bmp has been added. The background image allows to put vector contours by a raster sample.
The line of attributes of signs display contains modes that affect the display in the map. Into the panel there were added the modes "Text element specifying the width of the character" which allows to take into account the length of the text when displaying the sign and "an Element maintaining proportions". This property allows you to maintain the proportions of the element when expanding the sign.
