The CVI index (vegetation index of chlorophyll) has an increased sensitivity to the chlorophyll content in the foliage and is used from the beginning to the middle of the crop growth cycle. The EVI (Advanced Vegetation Index) index is used to assess the variability of development of crops in the growth stage with high biomass. Zoning maps are a synthesis of selected vegetation maps and soils on the basis of satellite images of high accuracy (10 m and 30 m) at different periods and under different climatic influences, which in turn determine the sustainably allocated agronomic zones on the field. Analyzing archival satellite imagery of past seasons, a potentially possible distribution of plant biomass is modeled. Zoning maps can identify problem areas on the map of fields, develop measures to increase productivity, and accurately predict crop yields.
The collection and processing of satellite imagery for satellite monitoring's data is carried out by Geosys company. Data of satellite monitoring is loaded from web service of the company and is accumulated in information base the

In KB "Panorama" the GIS WebService SE version 12.1.0 is developed for Windows and Linux operating systems. In the new version of service the application's architecture is improved. GIS WebService SE at the moment of receipt of the user requests forms virtual data handlers. With their help, the service manages the process of executing internal operations and evenly distributes the load across the system's cores depending on the capabilities of the server. At the first opening of data, GIS WebService SE in an automatic mode preliminary prepares them, sorting and indexing vector maps by means of trees. Changing the architecture allows you to increase the number of simultaneously processed user requests, improve stability at load, increase the throughput of the service and ensure the scalability of the server by further increasing the cores of the system.
The service operates around the clock and processes various types of spatial information (vector, raster and matrix data, point clouds, databases, three-dimensional information). GIS WebServi—Бe SE supports various types of operations: computing operations with objects, operations of objects search, overlay operations with objects, analytical operations with layers, construction of a road graph and the search for optimal routes, operations with XSD scheme and classifier, operations of creating the user data, operations of obtaining metadata, operations with the transaction log, service operations, work with the
The new version of the service allows you to work with three types of licenses: a fixed hardware license, a fixing license, a floating hardware license. The use of these types of licenses allows the user to choose the optimal variant of their server's work using a USB key or a binding to the server hardware.
GIS WebServi—Бe SE supports all international standards (OGC WFS, WFS-T, WMS, WMTS, WCS) through which the transmission and display of spatial data is carried out. The program provides the ability to issue tiles for any user or local coordinate system. The application is implemented on Windows and Linux platforms, compatible with Apache, IIS and nginx web servers.
In the map editor the mode of a merge of two identical map objects is added and the interface of the user is updated. At address search and search in Rosreestr for an address point the information on object is displayed at pointing the cursor of the mouse. Search by area is extended by the mode of manual input of the coordinates of the search area for more accurate selection of objects.
Possibilities of "Manager of map project " are expanded. The manager provides the ability to select data from the virtual folder of the map's project and update the composition of the map data layers according to the selection. The administration module has been updated. There is added the setting of permissions to use the project manager for the user groups.
The toolkit of developing the Web-applications the GIS WebToolKit SE has been improved, which expands possibilities 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 the GIS WebService SE (OGC WMS/WMTS) provides spatial information in the form of graphic images. Various types of high-altitude data are used as a digital elevation model: matrixes (in the formats SRTM, GeoTIFF, IMG, MTW), TIN-models, point cloud and others. At request the most accurate data onto a specified terrain site with a given resolution is automatically sampled. To transfer data of the digital terrain model to the Web, the WCS protocol is used. The relief data is represented as tiles and cached on the client.
