The program provides caching of information from a spatial database in the form of a cartographic representation already in established conventional symbols. This allows you to maximize the speed of multi-user access to this data. In the new version, for each GIS Server connection with the geo-spatial database, a separate directory can be assigned in the disk space for cache placing. This approach allows the server administrator to flexibly distribute the load to the disk subsystem.
The GIS Server allows not to reread from the database the previously received information and stored in the cache, even if this information has not been accessed for a while by any server client, or even if the GIS Server has been restarted. If data logging is available in the database, the GIS Server updates the data in the cache only in the part of the data that has changed since the previous access to the spatial data base. Logging of operations is carried out using an additional table in the database - "Log of data changes". The period of poll by GIS Server of the table of changes log is installed by the manager in program settings.
If the logging of operations is not performed in the spatial database, then the GIS Server must update the entire cache. To minimize the time and resource costs required for this operation, the new version introduces the notion of "time of data relevance". Now the cartographic representation generated by the original data set (geospatial database table or SQL query) is not recreated until the established interval of relevance of the received data has expired, even if during this period the operating system or the GIS Server was restarted. After the time of data relevance expires, the cartographical representation will be automatically re-configured if there are active connections to this data set on the GIS Server. If no one is connected to the dataset and the data timeliness has expired, the cartographic view will be re-formed at the first access of the user to this set. The relevance time for the data set of the spatial database is determined by the administrator of the Server GIS based on what spatial information is contained in this set, how much and how often it is updated for the server's clients.
GIS Server provides remote access to vector maps, remote sensing data, matrices, documents and spatial databases. There is supported a multilevel connection of servers among themselves for the distributed storage and processing of spatial data with automatic replication, backup and data protection. The program gives users the opportunity to make changes to geo-spatial data bases through the graphical interface of

For small scales of display the spherical model of a terrestrial surface is formed. When solving various navigational tasks, the spherical model allows you to explore the globe in a Web browser, to view cities, countries, continents, analyze their mutual location, and also make a quick transition to any point on the globe.
Search system is updated. The ability to select a search resource for address search and search by coordinates is added. This allows you to obtain geodata from various sources in the user interface. Management of map scaling is optimised, image animation at changing a scale of displaying a map is added. In the administration module there is added a customizing the parameters of several systems of address search, search by cadastral number on the portal of Rosreestr. There is added the ability to customize the boundaries for displaying 3D objects by scale.
The web applications development tool the GIS WebToolKit SE has been refined, 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 common OGC protocols and ISO standards. Service GIS WebService SE (OGC WMS/WMTS) provides spatial information in the form of graphic images. As digital model of a relief the various kinds of high-altitude data are used: matrixes (in formats SRTM, GeoTIFF, IMG, MTW), TIN-models, a cloud of points and others. At request there is carried out the automatic sample of the most accurate data onto the specified terrain site with a given resolution. To transfer data of the digital terrain model to the Web, the WCS protocol is used. The relief data are represented as tiles and are cached on the client.
As a source of spatial data, the Data bank of digital maps and remote sensing data can be. It provides the collection, storage, search and delivery of spatial data in exchange formats, a displaying the state of the data bank in the form of maps-schemes, the automated formation and updating of geo-covers.
GIS WebServer SE is used in the construction of closed corporate systems to ensure the protection of data having a security classification or a trade secret. GIS WebServer SE is certified for Level 2 of absence of undeclared capabilities. The new version of the program expands the application's capabilities in solving problems of analysis, management and long-term planning of the territories development. GIS WebServer SE is implemented using the toolkit of GIS WebToolKit SE, which can be used in development tools that use the JavaScript.

GIS WebServer AGRO version 2.2 is developed in KB "Panorama". In the new version the speed and reliability of work is increased at processing of a large number of cartographical layers and execution of long search requests. As sources of spatial data, GIS WebServer AGRO uses maps from the agricultural holding database published by cartographical service the
GIS WebServer AGRO allows you to use the full range of data needed for resource-saving technologies: satellite monitoring of crops, soil sampling points, soil fertility maps, application of GLONASS/GPS tools to monitor field progress and yield mapping, preparation for differential application of fertilizers, support of data collection from unmanned aerial vehicles, monitoring of vehicles and agricultural machinery, and others.
