In the new version, the GIS WebToolKit SE Web application development toolkit is enhanced, which extends the capabilities of GIS WebServer SE and can be integrated into other information systems. Access to data (images, vector maps, and terrain information) is provided by Web services using generally accepted OGC protocols and ISO standards. The GIS WebService SE service (OGC WMS/WMTS) provides spatial information in the form of graphic images. As a digital elevation model, various types of elevation data are used: matrixes (in SRTM, GeoTIFF, IMG, MTW formats), TIN-models, point cloud and others. The service provides the ability to publish three-dimensional terrain models unloaded in DB3D format. These models can be obtained from files of the COLLADA type, as well as from photorealistic three-dimensional models of unlimited size (TLS, OC3).
As a source of spatial data, the

In the dialogs "Map contents" and "Map object search" the list of objects is presented as a table with the columns "Name", "Code", "Character code", "Key", "Type". The ordering of the objects list by the values of elements in any column is provided, which is performed by clicking on the column header. Search of an object in the list can be performed by the value of an element in any column.
There is optimized a reading and editing of sets of vector maps with a volume of several GB, located on the GIS Server. Data display speed has been increased.
The toolkit consists of a set of visual components (supplied in source code) and a GIS core API for direct access to spatial data. The toolkit is intended for the development of client-server and desktop 32-bit and 64-bit applications that require processing and visualization of spatial data. Spatial data can be located both at the workplace (direct access to data), and in the local network or the Internet (components of access to the GIS Server or data exchange using international protocols are used).

The service's capabilities for working with databases and 3D objects have been expanded. A new request has been added a for displaying metadata for SQLite databases. In order to reduce the load on the server, it is possible to receive the list of tracks as one file, rather than sending each request separately. The format of the GetLayers request output has been expanded. Ability was added to display maps with dimensions exceeding 180 degrees (for example, a map of Russia, where the Chukotka Autonomous Okrug is located on the right). User interface of service's administrator has been improved. Possibility was added to set styles for layers and to view statistics of service's work. Uniform style and appearance of administrator for all operating systems has been implemented.
GIS WebService SE supports all international standards (OGC WFS, WFS-T, WMS, WMTS, WCS), which are used to transfer and display spatial data. The program implements the ability to issue tiles for 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 task of importing data of 3D model from TLS/OC3/DAE formats into DB3D format has been added. The TLS format is a binary file that stores the coordinates of textured 3D models with support for levels of detail, the models have a tiled structure. This format was developed by Agisoft company and implemented in the Agisoft Photoscan software product. The Sputnik software of the GeoScan group of companies works with the TLS format. The OC3 format is a binary file that stores coordinates and colors for points, which are combined into tiles distributed across levels of detail. The DAE (COLLADA) format stores a 3D model, the parameters of which are described in an xml file. If the model has textures, then they are stored in graphic files, which are usually located in a separate directory. DB3D format is a file of SQLite 3.0 and higher database, where the description of 3D models on the ground is stored in the form of tables. Viewing models together with a map is possible in the "Navigator 3D" task, the degree of detail of the models depends on the display scale.
Support of the packed MPTZ project has been added. A packed project may include a comprehensive representation of the territory in the form of vector maps of different levels of detail, rasters (terrain images) in the RSW format, elevation matrixes and matrixes of qualitative characteristics of the terrain, insets from the same data, the links to data from the GIS Server and from geoportals by various protocols. All data sets are packed into one file of MPTZ format. Links to external data are saved as a packed INI file. Maps and classifiers are compressed in 3-4 times, matrixes are compressed in 3-5 times, rasters are compressed in 3-10 time. Images of terrain in RSW and a matrix in MTW and MTQ contain 4 levels of data presentation - the most detailed base, generalised in the 1/4 scale, generalised in the 1/16 scale, generalised in the 1/64 scale. When displayed, the closest level of data representation is selected.
Speed of displaying MPTZ project is approximately the same, as at the initial uncompressed data. The speed of data exchange, packed into an MPTZ project, increases by 5 - 20 times, taking into account the decrease in the number of transferred files (for example, the original map can consist of several thousand files). The size of the MPTZ file and the number of sets in the project is not limited. Editing and exporting to other formats is not available for an MPTZ project.
The use of the MPTZ format makes it possible to change the system of storage, delivery and use of topographic and geodetic information in federal and regional government bodies, law enforcement agencies, large companies and for individual consumers.
Support for the RSCZ format - an RSC classifier file packed into a zip archive has been added. The volume of the stored file is reduced on average by 4-5 times without loss of data opening speed. RSC classifiers can be replaced at any time with packed files with the rscz extension. At opening a vector map, the GIS checks the presence of classifiers with extension rsc and rscz. The packed classifiers open only for reading.
At maps sorting with compression into MAPZ\SITZ format, the RCS classifier is compressed and recorded together with a map. Into one file MAPZ the works region from several thousand sheets with the classifier can be written down, that simplifies an exchange and application of vector maps.
ZIP has been added into the list of openable formats. When selected, zip is automatically unpacked onto the folder /tmp/Panorama.Cache/. The data opens in order of priority: the map project, vector maps, rasters, matrixes. This allows geodata projects to be archived, copied, and quickly viewed. The data in the archive opens for reading. After closing the unpacked data they automatically are deleted.
The operator.rsc classifier has been improved. For symbols of ships from layers "Navy. Combat ships and boats", "Navy. Special purpose ships", "Navy. Support ships and enemy ships", in accordance with KEUZ, the binding point is placed into the bow of the ship instead of the center of the symbols. Conventional symbols of object states: damaged and destroyed - are enlarged for clarity.
In the task "Save vector map in files of graphic formats" the list of formats of target files has been expanded. Along with BMP, TIFF, JPEG and RSW formats, the formation of a map image into a PNG file has been added. A fragment of a document of digital map of any type and content can be saved, including vector maps, rasters and matrixes, as well as geospatial data from external Internet resources (WMS and WFS - services). The ability has been implemented to save the map image by the selected area, by the page format and by the dimensions of the selected objects, for example, by the dimensions of the frames of the nomenclature sheets. The limitation on degree of increase in the image of rasters and matrixes is excluded. Rasters and matrixes which were drawn up to a scale 1:10, are drawn now without limiting the increase in a picture.
GIS "Operator" SE is a universal domestic geographic information system for power structures.
