Geoportal "Bank of spatial data" has been supplemented with a map of the Republic of Sudan, formed according to 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). 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 creation of clusters with using the "Classifier Editor" task. The considered task is available to users in the GIS "Panorama", "Workstation of cadastral engineer", "Workstation of agronomist" and other software products of KB "Panorama".

If the map is very overloaded, you can combine signs of similar meaning into groups and, if the conditions are met, instead of several signs, display one - a generalizing one. An automatic clustering algorithm is implemented to display densely spaced point characters.

The video tutorial provides an example of creating a "Cluster" for closely spaced conventional symbols on a map. When creating a "Cluster", you should enter the necessary parameters for correct display on the map, create the external view of the cluster, and you can create your own generalizing conventional symbol. Next, you need to add conventional symbols into the formed cluster. Maps with clusters customized in the classifier are automatically supported in all desktop and web applications, as well as in applications developed in the GIS ToolKit and GIS Constructor.

You can view the training materials in the "Video lessons" section.

In KB "Panorama" a toolkit for creating GIS applications the GIS ToolKit version 15.0.0 has been developed. In the new version, the component for connecting geoportals (TMapWMSPopupDialog) has been improved. The speed of loading and displaying tiles has been increased. The GIS core automatically evaluates the computer parameters: the number of cores, the size of the RAM, the bandwidth of the data transmission channel. Taking into account the performance of the system, a pool of independent threads is formed to load, process and display the received data. Multi-threaded data loading reduces delays when moving the screen, scaling the map, and performing spatial queries to the geoportal. For example, for a network with a bandwidth of 100 Mbps on a 4-core processor with a clock frequency of 3.5 GHz, the speed of displaying tiles from the KB Panorama geoportal increased 6 times, and the time to receive them decreased from 500ms to 70ms.

Data from geoportals can be saved into a pyramid of MBTILES tiles or into a raster for a territory selected by the user. In order to increase the speed of data access for the WMS protocol, caching of data in the form of tiles has been added. The data is saved in the form of a pyramid of tiles 1024х1024 in a folder of location of the geoportal cache. This change will allow the user to accumulate data locally and, in the absence of the Internet, use the already accumulated data cache. The ability to set the lifetime of the geoportal cache in seconds has been implemented (in order to update previously saved data).

The access component to the map object classifier file (TMapRsc) has been improved. There is added the ability to simultaneously edit the properties of several objects, select and transfer them to another layer or class, assign a common name, edit the visibility scale, digitizing direction, limits for changing the size of a sign, adding, deleting, changing the status of semantics. The function of assigning to several signatures of the attribute of specifying the size of the sign according to the length of the signature, assigning the attribute of prohibiting/allowing stretching to elements. This mode allows you to expand some of the elements of a vector sign (for example, automatically stretch the sign frame around long signatures), and shift the remaining elements (design elements: circles, squares, rhombuses). The shifted elements can be located both inside and outside the sign frame. To assign a no-stretching attribute to an element, select an areal or linear element of the sign and click the "Do not stretch the element when specifying the size of the sign" button.

The list of programmable signs on the demonstration map \data\shape\shape.sitx has been extended. There is added an example of a symbol - "Coordinates of a point on a callout". In the conventional sign parameters, you can select a semantics code to display in the numerator of the callout line, up to 6 semantics codes to display values in the denominator in several lines, and a semantics code to display to the right of the callout line. If you enter the number "-1" as the semantics code, then the X coordinate of the first point of the callout line will be displayed with an accuracy of cm, if the number "-2" is the Y coordinate of the first point, if the number "-3" is the H coordinate of the first point. Font options can be specified for the numerator and denominator strings (equally) and for the string that appears to the right of the horizontal portion of the callout line (for example, point number or other semantics).

New functions have been added into MAPAPI to manage the general display list of spatial datasets: request the number of elements in the list of datasets (mapGetViewListCount), request the name of the element (path to the dataset) and the type in the list of datasets (mapGetViewListItemName) and others. The examples and test data included into the GIS ToolKit installation package have been updated.

The GIS ToolKit is a set of visual components, classes and API functions of the GIS kernel for full-fledged work with spatial data. The toolkit is designed to develop client-server and the desktop 32-bit and 64-bit applications that require processing and visualization of spatial data. The GIS ToolKit classes and components are intended for use in the Embarcadero RAD Studio XE5 and higher programming environment (Delphi and C++ Builder) and are supplied with source codes. Components can be compared to "semi-finished products", using which you can quickly and easily develop your own geoinformation application. At the same time, the GIS kernel of the GIS ToolKit can be used not only in the Embarcadero environment, but in any development environment with any compiler that supports WINAPI standard function calls.

The new version of the program is available for download on the Download page.

Specialists of KB "Panorama" have prepared a video lesson on creating a backup copy of an aeronautical information database in PostgreSQL format. Complex of preparing documents of aeronautical information (ANI) is installed in addition to the GIS "Panorama" or GIS "Operator". The tutorial demonstrates the process of creating a database backup with use of the graphic interface pgAdmin4.

During the process of creating a backup copy, there are specified the name of the resulting file with the extension *.backup, UTF8 encoding, role name, and additional parameters of unloading are configured. It is recommended to regularly backup the database, especially when updating versions of the software package.

The complex of preparing documents of aeronautical information is a set of tools for maintaining an aeronautical data base, a modeling and analyzing the aeronautical situation, generating aeronautical maps and exchanging data with other information systems through export and import in the ARINC 424-19 exchange format and export in the AIXM 5.1 format. The task "Flight procedures design" is used to design the routes of departure, approach and landing and to analyze the safety of flights on them. The task "Assessment of compliance for aerodromes with the requirements FAR" is intended for the analysis of the aerodrome and the aerodrome environs for the suitability for operation and aircraft flights in accordance with the Federal Aviation Regulations.

Specialists of KB "Panorama" have prepared and placed the map of the Jewish Autonomous Region 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) 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".
