PRAGA is a geographical application for climatological, meteorological and agrometeorological analysis. It manages point and gridded dataset, and it enables gridding point data by using interpolation procedures contained in agrolib interpolation library. The most relevant variables are managed (air temperature, precipitation, air relative humidity, solar radiation, wind intensity and direction, reference evapotranspiration, leaf wetness). PRAGA uses specific widgets and libraries for visualizing data on maps and graphs.
