Specialists of KB "Panorama" prepared and placed the map of the Republic of Karelia on the geoportal
The map was led to the modernised classifier of large-scale plans of scale 1: 5 000 (
Free maps on the basis of OpenStreetMap data are available for download on the page "Digital maps".

If the connection to the database is successful, the "DTM Layers" tab displays a list of tables registered as intended for storing spatial data by DTM layers. On this tab, you can select all or individual tables from which data will be loaded into the DTM. If the connection to the database is successful, all the necessary parameters for creating a result map are filled, the "Run" button becomes available. When you click on it, the process of importing the selected DTM layers from the spatial database will start. Tables that were not previously marked are not included in the data import process.
You can get acquainted with the training materials in the "Video lessons" section.

The list of supported DBMSs for working with spatial databases has been expanded: PostgreSQL with PostGIS extension (St_Geometry data type), Oracle with Oracle Spatial extension (SDO_GEOMETRY data type), Oracle DBMS with ArcSDE extension (St_Geometry data type), Microsoft SQL Server (geogfaphy data type). For MS SQL Server, a work with a 2-dimensional metric in the WGS84 (EPSG: 4326) coordinate system is supported. To connect databases running MS SQL Server, the user's computer must have Microsoft SQL Server 2012 Native Client installed.
The parameters of connection to databases are configured by the GIS Server Administrator and are stored in a file with the DBM extension, which has an XML structure. The diagnostic protocol of the core libraries is located next to the protocol of the GIS Server operation and has the ".core.log" extension.

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.

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.
