Specialists of KB "Panorama" have prepared and placed the map of the Chukotka Autonomous Okrug 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".

Specialists of KB "Panorama" have prepared a video lesson of working the task "Import of Shape-files". The considered task is available for starting in the GIS "Panorama", "Workstation of cadastral engineer", "Workstation of agronomist" and other software products of KB "Panorama".

The video lesson demonstrates the types of data loading. When importing, the input data are loaded using the settings for the code composition of objects and semantic characteristics according to the map resource classifier, which is located in the "Parameters" tab. Possibility of displaying contents of a database table for a current set is shown. By means of the analysis of the table contents it is possible to estimate correctness of a choice of table encoding and to establish conformity of a table field and semantics from the classifier.

When loading data, you can use the "Primary classification". Primary classification tools are designed to evaluate the contents of unknown sets of input data in order to select the optimal classifier and configure it to import data. In this case, you can create a new classifier with an arbitrary name, perform classification and load data. Then, by visually viewing the loaded map, you can determine the optimal one from existing classifiers and configure the correspondence, or automatically assign the correct names to the added characteristics, and the corresponding image to the objects.

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

Geoportal "Bank of spatial data" has been supplemented with a map of the Algerian People's Democratic Republic, 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".

In KB "Panorama" the professional vectorizer "Panorama-editor" version 15.0 has been developed. The program has updated tools for preparing terrain maps, connecting external geoservices, managing the general list of data sets when displaying, editing digital classifiers and setting up conventional symbols. Possibilities of creation of the custom panels at the expense of including Python scripts have been expanded.

Updating "Panorama-editor" version 14 is free of charge if there is a valid technical support by downloading and installing a new version.

The "Map Editor" has been improved, the task "Expanding line object" has been updated. The new implementation of the mode allows you to perform additional digitization of multi-contour linear objects. When you select such an object, the nearest end or start point of one of the contours is determined. The contour selection is done automatically. Next, the user puts the necessary points to continue the contour.

Digitizing a linear object is similar to creating a new linear object. In this case, all auxiliary modes of creation are available: closing the contour; deleting the last point of the contour; snapping a point to a point or segment of another object; snapping a point to a virtual grid with a given step; copying a contour fragment of another object; creation of horizontal and vertical segments; creation of segments with a rotation of 90 degrees and others.

The mode "Create a copy of object" has been improved: when the property Snapping an object to a node of another object ("K" mode) is enabled, a snapping a created copy of object or group of selected objects on each mouse click is provided.

The task "Create objects" has been improved. Functionality for working with the object table filter has been extended. Classifier objects are filtered by such parameters as external code, key, object name, class/layer name. By default, the filtering mode is active. When you click in the filter value field, classifier objects are automatically selected according to the current value of the selected field. Elements have been added to display information about the current object, which allows you to copy the data about the object. Ability has been added to sort the contents of the table of objects in alphabetical order in ascending order by code, key or object name by pressing the left mouse button in the column header. The selected sorting mode is saved to the ini-file and restored during the next session. For better readability of information about the object, the table view has been changed. Display of the object view has been added into the first column. When you hover over it with the mouse cursor, an additional window with an enlarged image appears.

In the "Change of object type" mode for recoding areal objects into vector objects, the ability to build a new metric using a larger segment of the initial object has been added. This mode can be used, for example, for generalisation of the areal structures which are not expressed on the map scale. Into group of modes of "Measurement" the mode "Radial scale" has been added. On the background of the map, a scale of three rings is displayed, indicating the distance from the center of the screen on the ground. The distance between the rings is selected depending on the map display scale. The central ring is divided into 10-degree sectors, the cardinal direction are signed on it and the direction to the north is indicated. Into the "Autoshapes" group, the mode "Corner rounding" mode has been added. Editing can be performed in single mode (an object selected on the map) or group mode (a group of objects previously selected on the map or a logical set of objects). When working in group mode, all selected objects are automatically processed (after selecting the type of object to be created and entering the value of a rounding radius). When working in single mode, the rounding radius is determined by moving the mouse pointer. At processing of rotary corners of object, the possibility of rounding with a given radius is evaluated. If the sharpness of the corner does not allow construction with a given radius, the construction is performed along the maximum possible radius.

The task of connecting geoportals has been improved. The new version has increased the speed of loading and displaying tiles. 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.

Access to geoportal archive data has been added. Examples of such geoportals are the Sentinel Hub geoportal or the VEGA service. The task allows you to connect to images or data on the geoportal by specifying the date, the request period, or the percentage of maximum cloudiness of satellite images. To quickly change the image from the geoportal, a new dialog has been added that allows you to set the parameters for accessing archived data (date, period, cloudiness); to set an offset or reference to a point if the geoportal has a lower accuracy than the map or data with which the geoportal is combined; to set transparency color - to view several layers at the same time; to set the color of the filter to change the color scheme of the geoportal.

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. In order to update previously saved data, it is possible to set the lifetime of the geoportal cache in seconds.

When connecting geoportals that are not included in the general list (wmslist_ru.xml file), connection data is saved in the general list in the "User connections" section. This will allow you to quickly connect the previously used geoportal. The list of "User connections" allows you to add data to it, and remove data from it. The mechanism for replacing the user settings file wmslist_ru.xml with a new one from the installation has been improved. A copying of previously connected user portals has been added when replacing the settings file. In the new version the possibility of connection of dynamically expanded list of available geoportals has been added. When such a geoportal is selected, a GetCapabilities request is sent to the service, and based on it, the list is automatically expanded with relevant data in the form of a tree of available layers. Support for a proxy server with domain authorization has been added.

In the "Toolbars customizer" dialog, the ability to include python scripts into custom panels has been added. In the Tasks and scripts list, a Python scripts line has been added to select a script from the list, which must first be customized and checked in the Run applications dialog, "Scripts" tab. "Toolbars customizer" dialog allows you to create custom panels (toolbars) and fill them with frequently used modes from various application tasks and Python scripts. In the Run applications dialog, on the Scripts tab, a field has been added for entering a description of the script that will be displayed when the user clicks on the button in the "What's This?" mode. When writing scripts, several thousand functions of the GIS core (MAPAPI) are available. The function prototypes are declared as imported python scripts from the Users\Public\Documents\Panorama\py_mapapi14 folder. The order of application of MAPAPI functions, described in the document "Applied tasks". The procedure for applying MAPAPI functions described in the document "Applied tasks. Development of new modules", will also be valid for Python scripts.

The task "Map Legend" has been improved. The new tab "General list of data" has been added. This tab is designed to display a list of data in the sequence required by the user. The general list includes all types of data: maps, rasters, matrixes, models and geoportals which are included into the open document. To classify the type of data in the general list, the indication of elements in the form of pictograms is provided. Enabling and disabling the visibility of data is carried out by pressing the left mouse button (Left) in the display area of the "checkmark/cross" icon or the "spacebar" key. Names of data elements can be presented in the form of a full path or an abbreviated name. With the help of the modes "Above", "Below", moving of the selected data element onto one position is carried out. To change the order of displaying several elements of the list, the mode of transferring elements with the mouse (Drag&Drop) is available. Selection of list items is carried out using the key combinations Ctrl + Left, Shift + Left. To restore the standard display order by data type, you must use the "Set default order" mode. For processing all types of data, the following modes are provided: "Display", "Above map", "Visibility limits", "Go to ...", "Brightness/Contrast", "Add", "Add from directory", "Close". These modes are available in the context menu on the "General list of data" tab.

The task "Classifier editor" has been improved. Possibility of editing properties several objects at once has been added. Now you can select the necessary objects and transfer them to another layer or class, write down a common name for them, edit the visibility scales, add, delete, change the status of semantics, edit properties such as the digitization direction, the limits of sign resizing, and others. To do this, on the "Objects" tab, select the required objects in the table of classifier objects. If the table of objects displays only types of signs of objects, then you can select the current object by simultaneously pressing Ctrl+Left (left mouse button). If the table of objects is presented in string form, then the objects are selected by checking the box in the leftmost column of the table. Next, press the "Properties of selected objects" button and switch to the mode of general editing of all selected objects. Only the selected ones remain in the object table. In this mode, as well as without it, the properties of the currently selected object are displayed. But when editing any property, it is edited for all selected objects. If some property is highlighted with a yellow background or "others" is written on it, this means that it is different for the selected objects. Properties that cannot be edited at once for all selected objects are closed from editing. When you save, the edited properties are saved for all selected objects. You can exit the edit mode by pressing the "Properties of selected objects" button. You can reset the selected objects or select all currently filtered objects by clicking the "Reset selected objects" button. 2D and 3D views of objects do not have common editing for selected objects.

The task "Correction of metric of objects", included into the group of tasks "Check and correction of data", has been improved. The "Interpolate 3D coordinate of points" mode has been added into the "Others" mode group. The mode is intended for processing linear and areal objects, in which not all metric points have a 3d coordinate. The heights for such points are calculated from the spline using the heights of other points of the object metric.

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).

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

In KB "Panorama" the Databank of digital maps and remote sensing data version 8.4 has been developed. In the new version the tools of structural control of loaded metadata for geodetic points, analog maps and images have been expanded. When loading, the control of presence of obligatory fields and a check for duplication of data is carried out. By results of control the report is formed. Input control improves the quality of materials, stored in funds of spatial data of enterprises of geodesy and cartography of various levels.

Metadata loading speed has been optimized. Control on availability of server resources has been added. Schemes of rule by nomenclature sheets have been updated. Search of spatial data on territory by a specific nomenclature is supported. Procedure of loading territories crossing a meridian of 180 degrees has been improved. The list of diagnostic messages and error messages has been expanded.

Safety of the data is provided with differentiation of access rights on the basis of the means of safety which are a part of an operating system. Usual check of authenticity, the digest-authentication, system check of authenticity (web server means) and domain (Kerberos or ActiveDirectory) is supported. Additional safety is provided with use of a through authentication at work with a database. Connection to base occurs to the rights of the user working with system. The complex is adapted for work on a wide spectrum of operating systems (Astra Linux SE, ALT Linux, Elbrus, Ubuntu, CentOS, MS Windows and others) and architecture (Intel, Elbrus, Baikal). The program is registered in the register domestic ON at number 1862.

The databank of digital maps and remote sensing data is the basis for building infrastructure of spatial data of federal, regional and municipal levels, in corporate information systems. Within the framework of a single geoinformation space, the Data Bank of digital maps and remote sensing data realises gathering, storage, quality control, search and delivery of the spatial data in exchange formats. The spatial data selected by means of the program can be placed for the multiuser access on the GIS Server and be published according to the international standards OGC WFS, WFS-T, WMS, WMTS, WCS on application server the GIS WebService SE. Users can access data from both a thin client (by means of GIS WebServer SE) and from desktop applications (GIS "Panorama", GIS "Operator"). The databank of digital maps and remote sensing data provides construction of cloud warehouse of spatial data, provision of access to these data, the automated formation and updating of geocovers.

The current state of spatial data is displayed by means of maps-schemes that are maintained for each type of stored data: vector maps, remote sensing data, elevation matrixes and terrain models. It provides remote placing the sets of spatial data into file warehouse, keeping versions of stored sets, updating maps-schemes of data availability, the automated collection and formation of metadata, and the formation and updating of geocovers. Automated collection and formation of metadata is performed according to the standards of ISO 19115: 2003, Geographic information - Metadata and ISO/TS 19139, Geographic information - Metadata - XML schema implementation. The reduced copies of data images are automatically formed, checksum of files and completeness of data sets are checked. Placement of spatial data into file storage is performed with integrity check, control of data structure and content. The results of the work are recorded and are entered into the metadata base. Automatic backup of metadata and spatial data storage with integrity control and data recovery has been provided. Multilingual interface is supported.

The "Bank of spatial data" portal demonstrates the possibilities of organizing storage, accounting and and issuance of vector maps, remote sensing data, matrixes of heights and the terrain models. The portal contains vector maps in SXF format, generated on the basis of data from open sources (OpenStreetMap, VMap0). The spatial data includes maps of: subjects of the Russian Federation, countries and cities of the near and far abroad. In total, over 350 vector maps and 6700 matrix data with a total volume of 80 GB. Specialists of KB "Panorama" weekly update and refresh the content of the information on the portal. All published data is distributed free of charge under a free license.

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