Specialists of KB "Panorama" have prepared a video lesson on working the "Union of objects" mode. Users of the "Workstation of cadastral engineer", GIS "Panorama" or "Panorama-editor" can unite the polygonal objects using the tasks of the "Geodesy editor" complex.

The mode "Union of objects" is intended for uniting the areal objects at which semantic values coincide. For example, to automate the process of uniting the forest inventory allotments into forest blocks. The mode provides stream processing of map objects that have adjacent boundaries and the same attribute values. In this case, only areal objects of the type specified in the dialog, located on one map sheet, are processed. The result of the work are newly created objects.

Before using the "Union of objects" mode, you need to make sure that the data is correct. To do this, users of the GIS "Panorama" or "Panorama-editor" can check the structural integrity of digital data, the completeness and quality of the metric and semantic description of objects and perform automatic correction of detected errors. The task "Check of vector map quality" can work in two modes: checking the data and editing the data. In more details the mode work is considered in a training video on checking the quality of a vector map in the GIS "Panorama".

Creation and editing of objects on the map is carried out with the help of the applied task "Map Editor". The editor of a vector map is controlled with the help of the control panel placed when starting in the left part of the main program window. The control panel of the vector map editor can have a standard view (users of the "Workstation of cadastral engineer") or a professional view (users of the GIS "Panorama" or "Panorama-editor"). The standard panel of the map editor includes the minimum set of modes of creation and editing of objects of a digital vector map. The professional panel of the map editor represents the expanded variant of the standard panel and includes a number of modes providing additional service for creating digital vector maps "from zero".

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

Specialists of KB "Panorama" prepared and posted on the geoportal "Bank of spatial data" maps of the Vologda and Murmansk regions. Maps have been formed according to OpenStreetMap data. To work with maps, you can use the GIS Panorama Mini program 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) and saved to a packaged project (MPTZ). 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".

In KB "Panorama" the GIS "Panorama" version 14.2.4 has been developed for OS "Astra Linux Special Edition" (release "Smolensk") and OS "Alt 8 SP" (architecture x86-64). In the new version, the possibilities for obtaining cartographic data for the preparation of reporting documents have been refined, the interface for managing the selection of open digital maps has been improved, new tools have been added for specifying the dimensions of the created map objects, the display of sea maps has been refined, and the quality of the displaying the graphic symbols on the map has been improved.

In the program the possibilities of saving the data of digital maps into vector PDF format have been improved. The data of vector maps is saved into a PDF file along with rasters and matrixes of heights loaded into them. Customization of displaying map layers by means of the "Over Map" parameter allows to operate a moving of the required layers onto the foreground both at map visualisation on the screen, and at formation of the saved image for vector PDF file. Customization of a choosing a fragment of displayed area allows you to display an image of the all area of works or the fragment of a map limited by a rectangular area, the selected map object or the size of a current map window displayed on the screen. The vector PDF format preserves the quality of the map image at any specified display scale, which expands the user's ability to choose the scale of the formed PDF file. The mode of saving the map to PDF vector format can be used when preparing reporting documents.

Display of the list of open maps in the main menu in the "Window" section has been added. The list of open maps in the main menu provides more flexible settings for selecting the current active map when several digital maps are open at the same time. The menu clearly shows the names of the maps loaded into the program. In the list of maps, the currently installed active map is marked. Clicking on another item in the list of open maps switches the active map displayed on the screen.

The mode for creating an object with the selected mode "Horizontal rectangle" has been improved. When performing an interactive selection of a rectangle on the map through the context menu of the mode, you can call the dialog for setting the rectangle size by specifying numerical values for the width, height and area of the selected area. The lengths of the sides of the rectangle can be set in meters or kilometers on the ground, or in millimeters on the map. The area can be specified in square meters, square kilometers or hectares on the ground, or in square millimeters on the map. It is supported to specify the dimensions of the rectangle to create a new map object, taking into account the standard dimensions of the page printed on the device by selecting from the list of page format.

Displaying sea maps according to the S52 standard has been improved. The implementation of the procedures has been refined: Depval - formation of depth values based on attribute values for underwater obstacles, taking into account underlying objects, Udwhaz - requesting the code of the displayed symbol and display flag with taking into account the depth of the obstacle, or requesting the code of an isolated underwater hazard with a depth less than the safety contour, Wrecks - displaying the remains of a shipwreck.

The quality of displaying graphical symbols on the map and in the symbol preview windows of the properties' dialogs of the selected map object and the Classifier Editor has been improved. For graphical symbols, the image of which is stored in files, an anti-aliasing algorithm is applied during display, which allows you to get rid of the "pixelation" effect when the symbol size is changed in the classifier. The use of anti-aliasing when displaying graphic symbols expands the user's options for customizing the view of symbols in the classifier and improves the visibility of the map when displayed on the screen.

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

Specialists of KB "Panorama" have prepared a video lesson on working the modes the Calculation of occurrence of objects, Viewing of occurrence of objects and Control of occurrence of objects. Users of the "Workstation of cadastral engineer", GIS "Panorama" or "Panorama-editor" can calculate, view and execute control of occurrence of objects using the tasks of the Geodetic Editor complex. The tasks the Calculation of occurrence of objects and Viewing of occurrence of objects carry out overlay operation of multiple imposing of objects of two classes using the intersection method. Objects of the source classes are defined by two lists: the first list is the objects of the overlay and the second list is the objects to be analyzed. Lists of objects of source classes must be prepared in advance by means of a mode the Lists of objects.

Results of working the modes are the calculated values of the areas of occurrence of objects of one list (analyzed objects) onto objects of other list (objects of overlay). The program detects multiple occurrences of list objects and calculates the area of each occurrence in absolute units and as a percentage of the overlay object. The task of Control of occurrence of objects performs the operation of control of the mutual arrangement of objects of two classes. Objects of initial classes are defined by two lists: the first list - objects of overlay and the second list - the objects for control. The control requirement is that an object from one list is completely contained in one of the objects of another list. In this case, the objects can have common metric points along the border. The result of the mode operation is a list of objects of one list that do not satisfy the control requirement.

In KB "Panorama" the GIS "Operator" version 14.5.0 has been developed. In the new version, the tools for using terrain data received from unmanned aerial vehicles have been expanded, tools for report design and editing the vector maps have been updated, data import from formats DXF and S57 sea maps has been improved.

In the "Navigator 3D" task, the loading and displaying clouds of points from MTD models created in the "Panorama Photo" program has been accelerated. The "Panorama Photo" program allows you to create high-precision digital terrain models in the form clouds of points, matrixes of heights and orthophotomaps based on aerial photography from unmanned aerial vehicles. The cloud of points obtained in the "Panorama Photo" program contains point measurements sorted by blocks and by levels. Splitting into levels allows you to store points with spacing. On the first level, there are points with a step specified when creating the MTD model, on the second - with a step of 2 times more, on the third - 4 times more, and so on. In this case, points at different levels are not duplicated. This storage speeds up drawing of the 3D model by drawing blocks distant from the viewer with fewer points loaded from higher levels. The size of the cloud of points depends on the degree of the model's detail (density of points) and the area of the covered area. Displaying large MTD models requires significant hardware resources (RAM, video memory). In this case, the user can set up a filter of cloud of points to speed up drawing. Filter setting is available in the main menu of the "3D Navigator" task: "View" - "Filter of cloud of points". The filter determines the degree of thinning of the cloud of points during display: "Fine" - thinning by 2 times, "Average" - by 4 times, "Coarse" - by 8 times.

To use aerial photography data obtained from UAVs, the GIS also includes a "Complex of tasks for support of drones" and a set of tasks "Demonstration of photo and video materials with geolocation". "Complex of tasks for support of drones"performs a processing of photo and videos coming from the UAV, mapping of trajectories of their movement and preparation of reports based on the received data. The complex allows you to scroll through the video file recorded during the flight with a synchronous display of the location of the UAV on the map. The "Demonstration of photo and video materials with geolocation" complex is intended for display of photos of the area and video materials containing a coordinate binding to a place of shooting. Geographic images in JPEG format store a coordinate mark in an EXIF tag. The track of a video file (AVI, MP4) can be contained in the subtitles of the video file, or in the GPX, KML or NMEA-0183 format file of the same name. Also the GIS supports work with the remote video cameras connected to the Internet. The functions of viewing the video image, controlling the video camera and obtaining the results of the video analytics built into the camera are available.

The "Report Designer" task has been improved. Ability has been added to build a legend based on the maps contained in the inserts without opening them additionally. To do this, a list of data sources has been added in the Legend Formation dialog, which includes the main open project, as well as a list of maps contained in all the inserts available on the main project. Ability has been added to rotate the map in the insert. Map rotation is implemented in the form of menu items of the same name, as well as using "hot" keys. Each pressing of a "hot" key carries out rotating a map concerning the center of a displayed fragment by one degree to the left or to the right. The angle of rotation is stored in service semantics 31017 ROTATION ANGLE OF POINT ORIENTED SIGN (INSERT) and contains the value of the rotation angle counterclockwise.

The display of objects of the "Map Insert" type, implemented in the library of programmable signs shape.iml64, has been improved. The new algorithm allows cutting the map image according to the metric of polygons and multipolygons of arbitrary shape. Objects of type "Map inset" contain a link to the map file in the service semantics "Graphic file or map" (32769). Cutting the map image is performed according to the metric of the "Map Inset" object. Examples of objects of the "Map inset" type are contained in the map included in the GIS Panorama: File - Example data - C:\Users\Public\Documents\Panorama\Panorama14\data\shape\shape.sitx.

Displaying sea maps according to the S52 standard has been improved. The implementation of the procedures has been refined: Depval - formation of depth values based on attribute values for underwater obstacles, taking into account underlying objects, Udwhaz - requesting the code of the displayed symbol and display flag, taking into account the depth of the obstacle, or requesting the code of an isolated underwater hazard with a depth less than the safety contour.

When importing S57 sea maps, support has been added for datasets with updates of sea maps (ER profile), which are located in files with extensions 001, 002, 003, and so on. The update files must be placed with the source data set with extension 000 in the same folder or according to the folder structure according to IHO S57/S63 standards. The names of the source dataset and update files must match.

The task "Import files from DXF format" has been improved. "Create a set of maps" mode has been added into the dialog, which is designed for automatic processing of a set of selected data and creating a separate user map for each DXF file. As a result of the task execution, the list of generated maps is saved into the MPT project. There is added a recalculation of coordinates and sizes of characters from storage units specified in DXF: inches, feet, miles, millimeters, centimeters, meters, and so on. The formation of graphic primitives from the parameters of symbols specified in DXF has been improved, which allows you to reproduce the view of the original drawing without setting the conventional symbols.

In the "Data List" and "Map Legend" dialogs, on the Maps tab in the pop-up menu, the "Change X and Y" item has been added. When this item is selected on the current map, for all objects, the X and Y coordinates are changed between themselves. The menu item is available only for maps without a sign in the map passport "Limit the map territory by a frame". To cancel the flip of the map, you can perform a «Undo» or re-select the menu item.

The task "Highlight any area" has been improved. Changing the conditions for selecting objects selected by area has been simplified. The selection of objects by area is performed using the "Select inside the object" and "Select by any area" modes (polygon, rectangular fragment, lasso). At the end of drawing the area on the map, objects located inside the selected area are highlighted. To change the selection conditions, press the right mouse button and select one of the modes in the context menu: Highlight inside (delete intersection), Highlight with intersection (and inside), Highlight outside (delete intersection).

Marking of objects on the map according to various search conditions has been improved. If clusters are displayed on the map (generalized signs of closely spaced objects specified in the classifier), then the corresponding signs of clusters are displayed and marked, taking into account the number of signs and their location on the map.

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