The geoportal "Bank of spatial data" has been supplemented with a map of the Aquitaine region (France) formed using OpenStreetMap data. Source data was obtained from Geofabrik website. 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 GIS "Panorama"version 14.2.0 has been developed. In the new version the possibility of viewing in real time the video streams from the remote video cameras connected to the Internet has been added. The location of video cameras can be indicated on the map of terrain, plan of city, building, industrial area, three-dimensional model using various conventional symbols (objects). Objects can be moving if the camera is mounted on a vehicle. In the semantics of objects, a link to a video stream or a camera ip-address is indicated. Authorization parameters can be entered on each connection or stored in encrypted form on the client computer. Integration of geodata with video streams simplifies the construction of systems for monitoring the state of the area, traffic control, security systems, and others. To view a video image, select a camera object on the map using the "Ctrl+Shift+left mouse button" key combination. The program allows you to simultaneously view video in real time from different sources of video data. The size of the video viewing window corresponds to the resolution of the video stream. If necessary, the window can be expanded to full screen. Connection to the video camera is customized in the "Select Object" dialog. On the "Semantics" bookmark, you must select the "Link to video image" semantics, double-click to activate the "Settings of video camera connection" dialog, enter the url-link to the video stream or the camera's ip-address and authorization parameters.
HTTP and RTSP data transfer protocols are supported. Information about the connected camera and its current status will be displayed in the dialog. To save the authorization parameters, select the "Remember password" mode and enter the user code in the "User identification" dialog that opens. The user code must be the same for one user account in the operating system. To visually identify a camera with a map object, you must assign a "Camera Color". In this case, the object-camera on the map will have the color selected by the user and correspond to the frame of dialog of viewing the video image.
The applied task "Forecasting Emergencies" has been improved. In the new version of the task, spatial modeling of predicted emergency zones is performed in the UTM projection on the WSG-84 spheroid with with installation of the axial meridian at the epicenter of the accident, then the already prepared result is transformed to the map projection on which the user performed the calculation. This approach makes it possible to obtain the most realistic data on the ground by minimizing the errors in angular values and distances conditioned by the projection parameters of the original map. Thus into rectilinear segments of contours of objects of emergencies zones the additional points of the metrics are added for qualitative transformation of these segments and their transformation into arcs on a target map. These improvements do not apply to the computational problems of forecasting emergencies associated with a liquid spill, calculated from the matrix of heights. For these models, the calculation is carried out in the same projection that is set for the matrix of heights. The output of information onto the map based on the simulation results is supplemented by filling in the semantics of the affected areas, drawing the epicenters of accidents and signatures of the epicenters. The parameter "cloud transfer rate" has been added into the list of output parameters of the emergency model at a chemically hazardous object. According to the comments of the specialists of the Ministry of Emergency Situations, the names of individual parameters were corrected in the forms for entering the initial data and displaying the simulation results.
The task "Calculation of values of semantics for incoming objects" has been improved. Ability has been added to select the mode of source data processing in the presence of several maps - to process one or all open maps. When setting up the list of objects that are analyzed for belonging to the selected polygons, click on the "Filter" button to enable/disable the property "Set for all maps with the same classifier".
In the group of applications "Spatially-logical relations", the task "Transfer of the semantics of the incoming objects" has been improved. The settings for the task are divided into two bookmarks: General settings - selection of the input map and output map, setting the list of polygons and processing modes, and "Setting the semantics". "Setting the semantics" bookmark displays a table with a list of attributes with the possibility of multiple selection of characteristics for writing into incoming objects. Execution of process of transferring semantics has been optimized due to specifying of object-area and the list of unique numbers of incoming objects into the search context.
There is added a support of user semantics (attributes) of objects in format "name: value". When importing digital vector terrain data from SHP and KML formats, for characteristics whose field names do not coincide with the semantics keys from RSC, the user semantics is written with code 32862. User semantics can be used to record arbitrary properties of an object that are not described in the list of semantics of the RSC classifier. Any object can be assigned an arbitrary number of user semantics.
The "Map print" task has been improved. Ability has been added to page-by-page save the printed areas to JPG, PNG, TIF and PDF graphic files. When saving in JPG, PNG, TIF formats the number of files corresponding to the number of selected pages is formed. The file name contains file name and page number, for example, noginsk_1.jpg. When saving to PDF, it is generated one multi-page document.
The task "Report designer" has been improved. In the "Legend Formation" mode, the ability has been added of displaying in the legend table of the information about the number of objects of each type presented on the map.
The task of automated generalization of topographic maps has been improved. The mode "Setting the boundaries of channels visibility" has been developed. The new mode is intended for simplification of a network of channels. Network simplification is achieved by disabling the visibility of channels of the lowered importance in base and smaller scales of a map. Degree of the importance of the channel is defined by channel type, length and character of its location relative to other channels and the rivers. In this task, two categories of objects are considered: priority and excluded objects. Priority objects are objects whose visibility will not change. Rivers are such objects. Excluded objects are objects whose upper visibility limit will be lowered by 1 level relative to the base map scale. Channels are the such objects. Excluded objects can be transferred into a priority category in the following cases: the priority object adjoins the excluded one; the excluded object has length more the than specified minimum length (10 mm on a map), the excluded object adjoins a border.
Procedures of generalisation of the areal hydrography, setting the visibility of linear rivers and roads have been improved. The algorithm for shifting and sampling buildings in areas with an increased density of buildings per unit area has been refined. There is added a special handling of buildings intersecting with road network objects.
The profiling mode "By triangulation" of the task "Control of absolute heights" has been improved. To speed up the control process, the processing algorithm has been optimized. Map objects are read once, each object is profiled by all triangulation edges. The execution time of the control according to the new algorithm is reduced by 3-5 times. For a flat terrain with a large number of elevations and a small number of isolines, the "By triangulation" profiling mode eliminates misses that are possible when searching for heights in horizontal and vertical directions, which reduces the number of uninformative messages and facilitates the analysis of control results. The vertices of triangulation are: a point object (elevation, GGS point, mark of water edge), a point of the metric of an areal object with an absolute height (lake, reservoir), a point of the contour line's metric.
The task "Correction of objects metrics" ("Subobjects" mode) has been improved - the ability to unite linear subobjects with a common point has been added, provided that the subobjects are located at a distance from each other which is not exceeding the Matching tolerance. The tolerance setting is done in the dialog, by default the tolerance is 0.1 mm on the map. As a result of the operation, new subobjects with the metric of the united contours are created, or points of the subobject's metric are added to the main object, provided that the conditions are met.
Possibility of interpolation of the metrics of linear and polygon objects with the specified step has been added. Procedure is intended for addition into the metrics of objects of new points with a given step without change of the general geometry of object. It allows to transform correctly, for example, contours of objects of small-scale maps from cylindrical projections to conic and azimuthal projections.

In KB "Panorama" the GIS Server version 10.2 has been developed for the operating systems Astra Linux SE, OS Alt 8 SP, Ubuntu 18.04, CentOS 8, CentOS 7 and MS Windows. The new version of the program accelerates the synchronization of the state of spatial databases when they are updated on the server and their cartographic representation on clients when processing tens of millions of records with active image updating. The algorithms for caching the database on the server and the client have been improved, the amount of data transferred between the server and the client has been optimized when synchronizing the data state.
The GIS Server supports working with spatial databases controlled by PostgreSQL, Oracle and Microsoft SQL Server, which support the ability to access spatial data in accordance with the OGC 06-103r4 standard: "OpenGIS Implementation Standard for Geographic information - Simple feature access - Part 1: Common architecture" for their representation in the form of vector maps in the specified conventional symbols, editing the coordinates and attributes of objects, solving applied problems.
GIS Server provides multi-level connection of servers among themselves for distributed storage and processing of spatial data with automatic replication, backup and data protection. Such architecture reduces the load on the data transmission network tenfold, accelerates access to data and increases operational reliability.
