The new mode of editing the vector data has been added. Using this mode, the user can specify the coordinates of objects of interest to him on the ground (for example, cadastral plots, objects of power grids or gas economy). As data for editing, the user can select any open layer available for editing. The user can choose the external view of an object and a set of its characteristics from a standard library of conventional symbols (classifier) depending on the used subject (topographic, navigation, agricultural or forestry maps, etc.). When working with the classifier,the user can execute selection by a set of conditions: object type (for example, point or area) and object layer (for example, "Vegetation" or "Road network"). Information received from the built-in navigation device can serve as a source of information about the position of a terrain object. For convenience of using, a cancellation of last operation on map editing has been provided.
Direct and inverse geodetic tasks for execution of calculations on the terrain map have been implemented. Using these modes, the user can determine the coordinates of an object by a set of computational properties (starting point, distance, and azimuth). The selection of the starting point is carried out in an interactive form, it is supported the entering the coordinates from the keyboard in meters, in the current projection of the map. Calculation results can be displayed on a map or presented in numerical form. The received coordinates can be copied to the device's clipboard and used for transmission or further processing. For quick navigation, the ability to position the map window to any open spatial data layer has been added.
GIS "Panorama Mobile" allows you to open and edit the main formats of digital maps of GIS "Panorama" and popular geoportals on mobile devices based on the Aurora OS, to process information from the built-in GPS/GLONASS receiver. The user can prepare in advance a necessary set of spatial data in one of desktop products (GIS "Panorama", Panorama-editor, GIS Panorama Mini) and to transfer it into the mobile GIS "Panorama Mobile". The process of working with data is carried out autonomously, without connecting to the Internet. When the user moves, his current position is dynamically displayed according to the coordinates obtained from the GPS/GLONASS receiver. For ease of use, it is possible to synchronize the position of the map with the current location. To save the coordinates obtained during movement, a track recording mode is provided, which creates a separate map and puts the trajectory of movement onto it. For all objects of a map during the work the basic information is provided . The program is developed on the basis of the GIS Constructor toolkit, which provides components for creating mobile applications for working with digital maps in the C++ programming language using the Qt.

For OGC WPS, all operations available in the standard are supported: GetCapabilities, DescribeProcess, Execute, GetStatus, GetResult, Dismiss. Based on OGC WPS, all asynchronous information processing methods already available in the service are standardized, such as: checking intersections between objects of different layers; construction of intersections between objects; updating the data cache; building visibility zones; building matrixes of heights; construction of thermal and thematic maps and others. Using the commands of the standard, you can run any other requests supported by the service in synchronous or asynchronous modes. Descriptions of requests and their parameters can be obtained from the OGC WPS specification - GetCapabilities/DescribeProcess requests, and from the OpenApi 3.0 specification - a universal interface for users (clients) to interact with services (servers).
GIS WebService SE supports all international standards (OGC WFS, WFS-T, WMS, WMTS, WCS, WPS), which are used to transfer and display spatial data. The program implements the ability to issue tiles according to any user or local coordinate system. The application is implemented on Windows and Linux platforms and is compatible with Apache, IIS and nginx web servers.

The initial initialization of the dialog content is performed by information from the digital cadastral map and from the database of cadastral works. The cadastral map for the formation of a map-plan of the territory should be prepared in accordance with the
The map should be created with use of survey.v5 or survey.v6 classifiers. To draw objects in respect of which cadastral works are performed, it is necessary to use the objects of the "Cadastral plan of the territory" layer. An exception is the point object "Contour of the construction, OHS off-scale round" (key P_REALTYROUND), used for drawing point objects of real estate, which is located in the "Technical plan" layer.
The territory of execution of complex cadastral works should be digitized by the line of borders including all objects of cadastral works. An object within which complex cadastral works are performed can be of two types - "Cadastral block" (key S_BLOK) or "Boundary of complex cadastral works" (key S_CADASTRE). For an object of the first type, the semantics "Cadastral number" (key KADNUM) must be filled in, for an object of the second type - the repeating semantics "Cadastral number of the block" (key KADNUM_K).
You can get acquainted with the training materials in the "Video lessons" section.

A programming interface has been developed that allows the developer to use a graphics library for visualization based on his needs. The central element of most GIS applications is the display of spatial data. In this case, the image of a fragment of a digital map is formed using the functions of drawing graphic primitives (lines, polygons, points, and others) by means of a certain graphic library (Qt, GTK, wxWidgets, Xlib, and others). Often the choice of such a library is already determined at the design stage of the application and is a permanent part of the architecture. GIS Constructor provides software tools for implementing data visualization in an application with any selected graphic framework. This is achieved by separating the implementation of displaying graphic primitives into a separate library, which is accessed by the GIS core during the drawing process. As a result, the developer can use either a ready-made set of drawing functions, or implement them independently based on the graphics framework of interest to him. This makes GIS Constructor a universal tool for visualizing spatial data. The installation of the program includes examples of the implementation of drawing graphic primitives based on the Qt and Xlib libraries.
The functioning of the GIS application has been improved with a limited amount of available RAM. The need for the program to work in conditions of a small amount of system resources becomes relevant when using the embedded devices, portable laptops, specialized tablets and other similar devices. If there is a lack of memory, the GIS core automatically activates a buffer with a limited amount of memory and performs all operations with data using only this buffer. As a result, memory consumption by the GIS application is drastically reduced. The new version adds the ability to explicitly set a limit on the amount of memory used by the application for opening the data, when it is reached, this mode will be activated forcibly.
The ability to display only error messages in the diagnostic protocol has been added. This allows you to effectively determine the cause of abnormal behavior of a program that performs a large number of operations with spatial data. In this case, limiting the output by error messages reduces the volume of the resulting protocol and makes it convenient for further analysis.
The task of connecting geoportals has been improved. Into the list of geoportals the geoportal of Krasnodar territory has been added containing the layers: Administrative territorial division, Contours of fields of agricultural land, Fishing grounds, Vine plantations
Display of sea maps according to the S52 standard has been improved. There is clarified the implementation of procedures for forming depth values based on attribute values for underwater obstacles, taking into account the underlying objects, a requesting the code of the displayed symbol and the display flag taking into account the depth of the obstacle and requesting the code of an isolated underwater hazard with a depth less than the safety contour.
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 for work on a wide range of operating systems (Astra Linux SE, ALT Linux, Elbrus, Ubuntu, CentOS, QNX) and architectures (Intel, Elbrus, PowerPC, SPARC, ARM). The toolkit includes components of visual designing the GIS applications and library of a multiplatform multithreaded GIS core. GIS Constructor provides a cross-platform MAPAPI interface that allows a programmer to implement development in an operating system convenient for it. The developer can release GIS applications for a set of operating systems by simple assembly with minimal changes to the program source code.
