The service's capabilities for working with layers have been expanded. A request to get the state of the map has been added. It will allow to reduce the traffic for dynamically updated layers (for example monitoring of movement of motor transport) and not to receive a picture if the state of data has not changed. Possibility to limit scale of data output for a layer has been added. Possibility to set the type of data displayed for the layer is added: screen/printer. Support of transactions with graphic primitives in JSON and SLD formats has been added.
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 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.

Specialists of KB "Panorama" prepared and placed the map of the Novgorod region on the geoportal
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), a map of the administrative-territorial division of the region and a digital classifier. Publishing of updates in bank of spatial data is made by using the program of

The profiling mode "By triangulation" of the task
A new type of profiling of map objects has been developed - by triangulation edges. The triangulation vertices are: a point object (height mark, GGS point, waterline mark), a metric point of an areal object with an absolute height (lake, reservoir), a horizontal metric point.
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
The "Complex of 3D analysis" includes specialized tasks of relief analysis, modelling of derivative surfaces, creations of vector characteristics, tasks of forecasting and an accuracy estimation. The surface's model can display various properties of terrain, such as relief heights, concentration of pollution, amount of precipitation, level of radiation and others. Models of surfaces can be created by vector data of formats SHP, MIF, DXF, SXF, KML and others, according to information from database tables (DBF, XLS), and also can be loaded from formats SRTM, GeoTIFF, XYZ, LAS and others, in total more than 20 formats. Models of surfaces are used for formation of a three-dimensional terrain map, and also at solving the problems of a relief estimation: calculation of distances, calculation of the areas and volumes, profiling, building the visibility zones, determining directions of slopes.
The "Complex of 3D analysis" uses models of surfaces in the tasks of constructing isolines, formations of H coordinate (height) of map objects, when constructing flood zones and for modeling emergency situations. The "Complex of 3D analysis" also includes the tasks of predicting the area of an emergency oil spill and calculating the volume of earthworks.

It is recommended to start the data sorting mode after performing any procedures that change the metric or semantic description of vector map objects. Sorting of map objects can change: coordinates precision; kind of stored coordinates; encryption of data. When the "Sorting updated sheets only" mode is enabled, sorting will be performed only for those sheets on which objects were edited. This reduces sorting time. If the "Remove copies of the edited objects" mode is enabled, then after sorting it is impossible to restore the objects removed or edited earlier. This reduces the volume of data on the disk. If the "Generalization of multiscale objects" mode is selected, then for objects of the RSC classifier that have the
Multisheet and user maps can be packed into one file with compression of data. The packaged multisheet map has the MAPZ extension, the packaged user map has the SITZ extension. To increase the degree of compression, the precision of the object metrics is automatically converted to centimeters. The volume of the packed data decreases approximately in 3 times in comparison with volume of the initial data with the maximum precision of the metrics. Unpacking of data is carried out in memory in process of reading corresponding sheets and objects. If the map sheet is located in memory entirely it is unpacked in a multi-threaded mode when opening the data of sheet to speed up access. Packed maps are read-only.
