In KB "Panorama" the GIS Constructor for Qt Designer SE version 14.2.4 has been developed. In the new version the saving of digital maps in vector PDF format has been implemented, a type of programmable signs has been added to display bar charts. The list of scripts in the Python language has been expanded, the efficiency of searching and displaying data has been increased by optimizing the allocation of RAM.

In the program a saving of digital data to a file of vector format PDF has been added. The user can combine a set of open maps, save them in vector PDF format and transfer the resulting file for viewing in original quality at any scale using standard operating system tools. Individual layers can be excluded from the export by means of displaying layers of a map with use of standard functions of MAPAPI interface. Thus, the data of vector maps is saved to a PDF file along with rasters and matrixes of heights loaded into them. Data export can be performed at an arbitrary scale and for an arbitrary map fragment. For example, the user can select a map fragment on a small scale, and output it to a file on a larger scale, and save the image not of the entire work region, but only of its fragment, limited by a rectangular area, a map object, or the size of the current window. The resulting file in vector PDF format preserves the quality of the map image when viewed at any scale, which allows it to be used, for example, when preparing reporting documents.

New type of programmable signs has been added for displaying bar charts according to the semantics of objects with display in a legend of semantics values (in addition to a sign displaying values in percentage). The description of charts includes a list of codes of semantics corresponding to sectors of the chart. For each semantics the own parameters of displaying a sector are set. For all chart the maximum width and the maximum height of the chart are set. To the right of the diagram its legend is displayed. Texts of lines for signing of sectors are taken from semantics names, excepting repeating part of names. For example, if the semantics are called "Number of inhabitants under 20 years old", "Number of inhabitants from 20 to 40 years old", then the legend will contain the following lines: "up to 20 years old", "from 20 to 40 years old", and so on. The conventional symbol the "Bar chart" is shown in the data example on the map \Data\shape.

A script has been added into the list of basic python scripts that calculates the distance from the selected object up to several selected objects with recording into the semantics of the calculated value. RAM distribution has been improved when processing large data sets (tens of gigabytes and more than a hundred million objects). The speed of searching and displaying data has been raised.

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 new version of the program is available for download in the Download section.

Specialists of KB "Panorama" have prepared a video lesson on using the mode "Splitting of multiobject into simple objects". Users can use this mode in programs the GIS "Panorama" and "Panorama-editor".

The considered problem is intended for splitting objects with a complex metric (multipolygons, multilines, multipoint objects) into simple objects of the appropriate localization - areal, linear or point. To process several objects, you must first select objects using the "Search and mark" dialog, or using interactive modes - by area, by type of selected object, and others.

You can get acquainted with the training materials in the "Video lessons" section.

Geoportal "Bank of spatial data" has been supplemented with a map of the Republic of Colombia, formed according to OpenStreetMap data. To work with the map, you can use the GIS Panorama Mini program or other software products of KB

The map was led to the modernised classifier of large-scale plans of scale 1: 5 000 (map5000m). Publishing of updates in bank of spatial data is made by using the program of Databank of digital maps and remote sensing data.

Publishing contents of bank of spatial data on the geoportal and data access for downloading are implemented by means of GIS WebServer SE.

Free maps on the basis of OpenStreetMap data are available for download on the page "Digital maps".

Specialists of KB "Panorama" have prepared and placed the map of the Republic of Mari El on the geoportal "Bank of spatial data". The map was formed using OpenStreetMap data. To work with the map, you can use the GIS Panorama Mini program or other software products of KB "Panorama".

The map was led to the modernised classifier of large-scale plans of scale 1: 5 000 (map5000m) 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 Databank of digital maps and remote sensing data. Publishing contents of bank of spatial data on the geoportal and data access for downloading are implemented by means of GIS WebServer SE.

Free maps on the basis of OpenStreetMap data are available for download on the page "Digital maps".

Specialists of KB "Panorama" have prepared a video lesson on using the "Information about object" mode. The considered mode is available to users in the GIS "Panorama" program.

This dialog is used to view information about a single object, consisting of one or more parts. The mode displays the distribution of the numerical values of the characteristics over different parts of the object and its general measuring properties. For example, for a highway, the number of lanes, pavement material, speed limit, slope, and other properties may change. Sections of the road, where the properties are constant, can be digitized by separate objects. Different sections can be logically linked into a single road due to the common property the Road number, Own name or Designation.
