On the geoportal "Bank of spatial data", the map of the island Crete, formed according to OpenStreetMap data, was updated.

The source data was obtained from the Geofabrik website. For work with the map it is possible to use the program of GIS Panorama Mini 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.rsc). 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 and images".

In KB "Panorama" the examples of using the tools of GIS WebToolKit SE in web projects are developed. Examples demonstrate the possibility of using GIS technologies in finished and developing projects. Spatial data can easily be added onto any page of the site and interaction between the web application and the GIS is organized. The examples demonstrate the display of terrain maps, remote sensing data, aerial and satellite imagery materials, matrixes of heights and other spatial data on the site pages, in a separate browser window and in a frame.

Methods of organizing interaction between applications, methods of establishing link between objects are shown. The updated documentation describes an example of working with a database, which allows you to display tables, establish a logical link between database objects and map objects, search for objects by table records and vice versa, using the mechanism of linked records.

The GIS WebToolKit SE tools allows you to create web applications that display cartographic information about the area, get information about the characteristics of map objects, create new ones and edit existing objects. Provides access to the infrastructure of spatial data (vector, raster, matrix maps, remote sensing data), performing of special calculations. It can be used on Linux-based systems.

GIS WebToolKit SE supports spatial data exchange protocols by standards of Open Geospatial Consortium (OGC): Web Map Tile Service (OGC WMTS), Web Map Service (OGC WMS), Web Feature Service (OGC WFS), Web Coverage Service (OGC WCS) and additional requests for execution of special calculations. GIS WebService SE service is used as a source of geospatial data. It provides obtaining a graphical image of the map, the geometry of objects and various help information about the map objects, an obtaining the spatial information about the terrain, performing calculations and measurements on the map.

In KB "Panorama" the GIS Constructor for Qt Designer SE version 13 was developed for the CentOS 7 operating system. The new version improves the reliability of working the multithreaded GIS applications that process spatial data hosted on the GIS Server. GIS application in the background mode monitors the status of virtual channels and, if necessary, reconnects. GIS Constructor implements support for a single geographic information space managed by servers of spatial data (GIS Server) and application servers (GIS WebService SE). Due to the ability to connect to the GIS Server, users of GIS applications can directly connect to geospatial data bases, view and edit tables in the form of maps in specified conventional symbols. Support for interaction with the GIS WebServiсe SE allows you to access spatial data according to international standards OGC WMS, WMTS.

CentOS (Community ENTerprise Operating System) is the popular distribution kit Linux based on commercial Red Hat Enterprise Linux and compatible with it. The distribution kit consists of the free software with the open code. The source codes for the operating system is provided under the GPL licence. The operating system is reliable and flexible in configuration, supported by a large community of developers, thanks to which it is constantly being developed and updated.

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 to work on a wide range of platforms and supports operating systems such as Astra Linux SE, MSVS, CRTOS "Neutrino", "Elbrus", "Zarya", Ubuntu, Alt Linux, QNX, CentOS and others. It can be used in computer complexes with processors of architectures ARMv7, Elbrus, PowerPC, Intel x86, Intel x64 and others.

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

On the geoportal "Bank of the spatial data", the maps of regions of the North Caucasian Federal District, which were formed according to OpenStreetMap data, were updated. The composition of the maps includes the Republic of Dagestan, the Republic of Ingushetia, the Kabardino-Balkar Republic, the Karachay-Cherkess Republic, the Republic of North Ossetia-Alania, the Chechen Republic and the Stavropol Krai. The source data was obtained from the Geofabrik website. For work with the maps it is possible to use the program of GIS Panorama Mini or other software products of KB "Panorama".

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

On February 13-14, 2020, the 11th International Scientific and Practical Conference "Geodesy, Mine Survey and Aerial Photography" will be held in Moscow. Within the framework of this event, the specialists of KB Panorama will hold a master class the "Dynamic 3D-terrain models. Variants of creation and types of source data." Possibilities of software products the GIS "Panorama", GIS "Operator", GIS WebServer SE and others will be demonstrated to participants of event.

The three-dimensional terrain model in the geographic information system is a three-dimensional dynamically changing scene, consisting of terrain, ground, underground stationary and moving objects. For its construction, a wide variety of source data can be used: a vector map, a matrix of heights, a triangulation model of the relief and terrain, a point cloud, three-dimensional models of objects, aerial photographs, and three-dimensional tiles. In addition to such a variety of source data, the process of transmitting data and displaying a three-dimensional terrain model is complicated by the large amount of data and limitations of the transmission channels in the case of using WEB applications. This entails the need to create an optimal 3D terrain model.

The solution to the problem of large amounts of data and their transmission can become a tile representation of three-dimensional data - a format that contains a pyramid of the scales of a three-dimensional model in the form of small blocks for each level. At the master class, the specialists of KB "Panorama" will talk in more detail about the tile model, as well as demonstrate the technology for creating a three-dimensional terrain model based on all the variety of source data using the company's software products.

At the international conference, participants will be able to get acquainted with the latest Russian and foreign companies in the field of technology, equipment and software for collecting and processing geospatial data. Specialists of branch will discuss prospects of developing the market of the geodesy, mine survey and aerial photography, will visit master classes of the leading companies, will share experience with their colleagues.
