GIS WebServer AGRO provides tools of analyzing data of fields

14.05.2018

In KB "Panorama" the GIS WebServer AGRO version 2.5 is developed, in which possibility for the visual analyzing the data of satellite monitoring of agricultural land is added. The new version of the program allows you to view the data of vegetative indices NDVI (Normalized Difference Vegetation Index) and GNDVI (Green Normalized Difference Vegetation Index), characterizing the development of plant biomass during vegetation.

Data of satellite monitoring is loaded from web service of Geosys company and is accumulated in information base the GIS "Panorama AGRO" with a binding to a field's contour. In GIS WebServer AGRO, the viewing and analysis of vegetation indexes matrixes from a single agricultural enterprise base has been added. For the analysis of numerical values of the vegetation index by matrixes of qualities the tool "Value of matrixes in a point" is intended. Multiplatform cartographical service GIS WebService SE provides provision of data. Data exchange with the service is performed according to international open standards OGC: WMTS, WMS, WCS and WFS. As a source of data of satellite monitoring (numerical values and images of vegetation indexes) for GIS WebService SE are the maps and the matrixes placed on the GIS Server. Publication of data on the GIS Server is performed automatically, at the time of loading the satellite monitoring's data, in the time mode close to the real one.

There are supported a retrospective analysis of images of several matrixes of the vegetation indexes characterising development of a biomass of plants at various stages of vegetation, and also a viewing the maps of zoning and graphs of daily average values for several seasons. The zoning maps, built using historical NDVI imagery, allow us to identify problem areas on the map of fields, and accurately predict crop yields.

The new version adds the ability to save the last location for each user of the program, in the map editor, the group operations for deleting and moving map objects are added. Modes of selecting objects of a map are expanded: there are added a selection of objects arbitrarily specified on a map and selection of objects by a conventional symbol of selected object. You can see the example of the working the GIS WebServer AGRO on the page of the demonstration project "Agroportal".

The new version of the program is available on the site in the Download section.
