  1. 1. Analysis of the sunlight rays anglefall on the terrain and reliefobscuration Vinice - Rača, SKJuraj Furdík, Rostislav Ondruš,Dávid Murín, Daniel Furdík
  2. 2. • Quality of vineyardsdepend on many aspectsthat are determining theterroir, such asdeclination of theterrain, orientation tothe cardinal points, timeof exposure to the sun,altitude and many more• In these analysis wewere researchingobscuration and angleof rays under which theyfall on the terrain
  3. 3. • Our analyses were made from observation of these days:1) Spring equinox, 20th of March 20122) Summer solstice, 21st of June 20123) Autumn equinox, 23rd of September 2012• In each day we were considering three main day times,namely 2 hours after the sunrise, the midday and 2 hoursbefore the sunset
