Specialists of KB "Panorama" prepared a video lesson
Tools of transformation are in the section "Transforming rasters", which can be opened using the menu item "Run applications". In a video lesson a work with dialog "Transform raster map" is shown. Users will get acquainted with various types of transformations and interpolation methods. The actions shown in a video lesson will help to learn how to carry out a placing a raster or to transform the image.

In KB "Panorama" the
The automatic correction of the metrics of polygon and linear objects is improved. In polygon objects, there are removed the outliers and vertex duplications, all types of self-crossings, crossings of contours and errors of locations of subjects are corrected. Adjacent contours of one object are combined, intersecting contours are divided into separate objects. In the objects having errors of locations of subjects, the description order is corrected: the subject having the maximum area becomes the main one, the subjects located inside other subjects are stored into separate objects. In linear objects, there are removed the outliers and vertexes duplications, coinciding segments, the self-joining is corrected (joining of non-consecutive segments of one contour). The contours having the self-joining, are divided into separate objects. To correct the metrics of objects, it is necessary to perform "Check of self-crossings and locations of subjects" in the "Edit" mode. The corrected objects have a topologically correct metric description, which provides the calculation of correct areas, simplifies the construction of road network graphs, and allows you to combine and cut areas of vector data according to specified conditions. Automatic correction of the metrics of map objects allows you to speed up the processing of vector maps obtained from any sources that do not have a strict standard for checking the metric information.
In the task the "Checking the quality of a vector map" according to a control scheme, tools of checking the metadata of the map are added. Metadata is formed by the task the "Map passport" according the standards of ISO 19115:2003, Geographic information - Metadata and ISO/TS 19139, Geographic information - Metadata - XML schema implementation. Metadata is saved in the XML format as a separate file onto each sheet of the map. Metadata allows you to enter additional information about the map (data on the manufacturer, data on the technology of creation) and use it in the conducting the automated banks of the spatial data.
In the "Map Editor", the tools for viewing the results of checking the vector map are improved. To improve the quality of checking the metrics of objects of vector map, the checking program performs an excessive number of tests that can generate repeated error messages. The ability to filter repeated messages has been added into the program of viewing the checking results. To disable repeated messages, click the "Mark repeated messages" button and select the option "Hide marked messages". The mode of uniting (merge) selected polygon objects has been improved. There is implemented a formation of subobjects-multipolygons from those selected objects that are located from the objects to be merged at a distance that is greater than that specified in the parameters of the "Map Editor".
The mode "Formation of a common external border" of the Map Editor has been improved. This mode allows you to create a common external border for map objects that are at an admissible distance. The allowable distance between adjacent objects is set in the parameters of the Map Editor (join tolerance).
Display of vector symbols is improved. New symbols automatically compose complex labels, which are used to indicate the characteristics of forests, bridges, dams, tunnels, rivers, canals, fords, ferries, passes and other objects on the map. The main feature of complex labels is the presence of a horizontal line - the separator of the upper and lower labels of the main characteristics. Each label can be formed from several characteristics of an object and contain fragments of permanent text between characteristics. For each digital characteristic, you can specify the number of digits after the decimal point, for symbolic characteristics - word splitting and replacement with abbreviated names. The abbreviation of words of symbolic characteristics (of the type “Name”) is carried out according to the semantics “List of abbreviations”, which contains the corresponding full and short names (abbreviations).
Sorting the maps of SITX format with encryption of stored data by the user password is accelerated.
The document "Description of technology of creating and updating digital topographic maps" has been updated. This document describes the technology for creating and updating digital topographic maps based on remote sensing of the Earth. The technology is based on the use of software the PHOTOMOD DFS and the GIS "Panorama" x64.
In the “Navigator 3D” task, there is complemented the mode of loading models from formats of Collada, TLS, OC3 into the DB3D three-dimensional tile database. For all formats of the original models, editing the coordinates of the model binding point is supported.
The task “Converting geodetic heights of WGS-84 to normal heights” has been improved. It is intended for transition to heights on a geoid (normal heights) from geodetic heights on a general ellipsoid WGS-84. For example, downloaded from the SRTM format (radar topographic survey) and others. The inverse transformation of matrixes from normal heights (mean sea level) to the system of geodetic heights WGS-84 has been implemented.
For finding the causes of repeated errors in the program's work the "Diagnostic log" is added. If some action with the program causes an error, then for its diagnosing, it is desirable to enable the "Diagnostics log" and to repeat the action causing an error. The diagnostic log is created in the folder \ProgramData (or \Users\All Users), which is usually located on the C: drive. Enabling the diagnostic log may be done in the menu \Options\Diagnostics log. Enabling the mode and displaying the name of the log file is also implemented in the "Placement of data" dialog - menu item \Options\Placement of data. The generated log file describing the error can be sent to the technical support of KB "Panorama".
The new version of the program is available for download in the
KB "Panorama" prepared a digital geographical map of scale 1: 1 000 000 in format SXF onto the territory of the Republic of Korea.
The map contains information about the quantity of inhabitants for cities and the names of settlements in Russian. As additional materials the World map of scale 1: 5 000 000 and data of

Representatives of the leading Russian companies working in the fields of geodesy and cartography took part in the international seminar. Specialists of KB "Panorama" made presentations and conducted master classes. Technologies for creating and updating digital topographic maps based on data from unmanned aerial vehicles using the
Representatives of Russian companies demonstrated to Uzbek specialists the latest technologies for using remote sensing data obtained from unmanned aerial vehicles to create accurate cartographic materials. During the dialogue, participants discussed the practical and economic aspects of the operation of UAVs and the processing of survey results.
The practical part of the seminar was held in Okhangaron District of Tashkent region, where UAV flights were carried out and aerial photography was performed. Photogrammetric processing of the obtained materials was carried out with the help of

The report of the Deputy General Director of KB "Panorama" Demidenko Albert Gennadievich presents the possibilities of software technologies for automating the processes of collecting, storing and publishing spatial information in the context of the wide use of geoservices. The updated technology of automated generalization of topographic maps is adapted for application of the data placed on the
Possibilities of processing and the analysis of three-dimensional terrain models are expanded. To maintain the base of three-dimensional models, tools for importing 3D data from PHOTOMOD, Geoscan and others programs have been developed. Visualisation of three-dimensional views in the
Placing digital maps, materials of remote sensing the Earth, elevation matrixes, spatial objects and three-dimensional models in the Databank is an effective tool of providing geodata for territorial administration, designing and building planning. The use of a geo-cover base solves the problems of limited performance of traditional methods of storing spatial data in a file system, automates the process of updating spatial data and allows you to organize cloud GIS technology.
