The initial opening of large vector maps, containing several million objects and more has been accelerated after importing data from exchange formats or databases - from tens of seconds to fractions of a second. There is improved a positioning of objects added onto a map in the display sequence chain, as when sorting a map. This improves the quality and ease of editing the map, speeds up the initial construction of the object tree when opening the datasets.
In the new version of the program, the transformation of vector maps into a given coordinate system has been accelerated by 4-6 times. The transformation process is called on the fly when the data of maps and geoportals in different coordinate systems are added into one window. When transforming on the fly, a copy of the input map is created in the map subdirectory with a name containing the name of the passport file and the current date.
Into the graphical component of
The parameters of connection to geoportals can be flexibly configured for each user by editing the wmslist_ru.xml file.

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 number of lines with conventional symbols of objects in a block can be changed. A block on the map is created in the form of a grouping of objects by semantics, which allows further general movement, deletion and other group operations.

Displaying sea maps of S57/S52 standards has been improved. In the s57navy.rsc classifier for attributes that have a list of classified values (Attribute type: L - CATAIR, CATACH, ... TECSOU), property the "Repeat allowed" is set. When exporting and importing data, lists of attribute values (1,7,, 30) are written and read. For display of lists of values, into the
Algorithms for storing "point cloud" data in MTD datasets have been improved. Packing data, taking into account the area of the processed area and the specified storage accuracy, allows you to reduce the size of created MTD files by up to 4 times, which can be from several tens of Gigabytes to Terabytes. New algorithms improve the accuracy of terrain description over a larger area and accelerate the construction of 3D terrain models.

The "Display/Inform window" item has been added into the Options menu to enable or disable a pop-up message that informs the operator about the result of the action performed in the map window.

The list of supported formats of data for export of a matrix of heights has been expanded - TXT, TIFF, KMZ. The formed KMZ archive contains the KML (Keyhole Markup Language) project file and a set of pyramid tiles for the saved territory. The KML file contains a description of the matrix data parameters: the names and coordinates of the matrix binding, as well as the priority of their display.
The task of creating a three-dimensional terrain map has been improved. Possibility of saving the model into DB3D format has been added. DB3D format is intended for storing and displaying pyramids of three-dimensional tiles packed together with metadata tables in SQLite format. It provides fast tile-based output of spatial information in accordance with the requested scale and territory. The volumetric tile matrix is of type GoogleCrs84Quad. Level of scaled texture detail of data and the coverage area are not limited. Surface textures are stored in JPEG and PNG formats. Saving a terrain model to the database accelerates the display of a three-dimensional terrain model in desktop and Web-applications, makes it possible to work with the model later without the initial cartographical data.
