On the website of KB "Panorama" the fourth lesson of the series "Development of applications for GIS "Panorama" was published. In this lesson we explain the mechanism for implementing stream tasks on the example of creating a mode of exporting map data into PostgreSQL database.
From the training materials, you can learn about the features of spatial data storage in PostgreSQL databases and how to access them from your own applications. The lesson includes the source code of task for exporting vector map objects into PostgreSQL and the ready-made mode library. This material will help to understand not only the mechanism for creating stream tasks for the

Numerical values of vegetation indexes are calculated by external service of satellite monitoring. The result is provided in the form of a matrix of qualities with a discreteness corresponding to the resolution of the original image. Data of satellite monitoring are provided by the Geosys company.
The new version of "Panorama AGRO" supports a viewing and analysis of the matrixes of vegetation indices of the following types: Normalized Difference Vegetation Index (NDVI), Chlorophyll Vegetation Index (CVI), Enhanced Vegetation Index (EVI), Green Normalized Difference Vegetation Index (GNDVI). The most popular in agriculture is the index NDVI (Normalized Difference Vegetation Index) - the normalized relative index of vegetation, according to which it is possible to judge the development of plant biomass during vegetation. According to numerous scientific publications, according to the NDVI index, crop yields can be predicted with high accuracy. The vegetation index NDVI is changed all season and its values are different during the growth, flowering and maturation of plants.
GIS "Panorama AGRO" allows to use full range of data required for technologies of exact agriculture: data of satellite monitoring the crops, soil sampling points, maps of soil fertility, application of GLONASS/GPS tools for monitoring the field progress and yield mapping, preparation for the differentiated application of fertilizers, support of data collection from unmanned aerial vehicles, monitoring of vehicles and agricultural machinery, and others.

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.
