2. THE PROJECT CHARACTERISTIC
• Analysis of the natural conditions forms an basic part of the urban and
landscape study "Vineyard - City District Bratislava - Rača", which on the
order of the Local Authority city district Bratislava - Rača is compiled by
a team of authors led by prof. Ing. arch. P. Gal, PhD. and Ing. arch. J.
Furdík, PhD. Faculty of Architecture, STU in Bratislava was coordinator
for project of this analysis.
• The social order was based on the role of mutually contradictory
pressures on the territory of Rača vineyards, where on the one side are
the defenders of the interests of the vineyard and on the other, the
interests of owners and developers.

3. • Delimitation of the area was given by city districts and was designed by current borders of
vineyards in the Master plan of Bratislava despite the fact that, even now, are functional and
promising area of vineyards outside these borders, it means, that he was not interested in
solving this problem with a comprehensive review of all the available areas in the cadastral
territory of the city district Bratislava - Rača. Solved territory consists of five compact sectors
with a total area of ​​251.7 hectares.

5. • Analysis of the natural conditions (in her summary of terroir) should provide an
objective basis, which would determine the most suitable localities for the
maintenance of vineyards in the solution area. Of course, this analysis of the
vineyards in Rača is not sufficient. The next steps must be completion of urban
studies and planning scheme of a particular legal system and support mechanisms
that make real the existence of a specific viniculture in immediate contact with the
urban structure of Bratislava.
• Analysis of the natural conditions, with emphasis on the analysis of the spatial
characteristics of the territory, using a digital terrain model (Eurosense Ltd.)
becomes the model initial analysis project vineyards in Slovakia, which expresses
the terroir key features affecting the quality of wine production.
• Digital terrain model (DTM) from EUROSENCE SLOVAKIA with geographical
information systems GRASS and Quantum GIS (open source softwere) provide the
basic framework for spatial analysis of natural conditions in the Rača area of
vineyards.

6. DEFINITION OF TERROIR

7. Units of quality SOIL ECOLOGY UNITS

8. HEIGHT GRADES the altitude
Height grades legibly reflect the altitude, which affects the climate of
individual plots, in the valleys it is a longer period of fogs, at higher
altitudes is a difference of 1 ° C per 100 meters of height.

9. Declination of relief
The declination of relief in direction of the catchment curve in relation to the
orientation to the cardinal points has a basic influence on the amount of energy
incident on the individual vineyard plots and economy working of vineyard.

10. The projection of declination in vineyard plots
The suitability of declination is from 5 ° to 25 °, optimally from 5 ° to 15 °. The
projection of declination in vineyard plots, which have been formed historically,
determines their suitability and orientation to choose the type of grape.

11. Orientation to the cardinal points
Orientation to the
cardinal points of
the relief
together with
declination
determine the
appropriateness
of the choice of
vineyards plot in
the solution area.
The shading by
horizon is
important too,
because the
proximity of the
forest and the
Small Carpathian
Mountains. Most
favorable
orientation is in
the order of 1.
south, southwest,
2. southeast,
west.

12. The sunlight rays angle fall and the shading of relief
The sunlight

Comprehensive
view on the

provides
analysis of the
sunlight rays
angle fall and
the shading of
relief. Given
the growing
season vine in
the analysis
singled out
three key
days (20.3, 21.6, 23.9) and three breakthrough times - times of the day (2 h after
sunrise, noon, 2 h before sunset). The average of the sunlight rays angle falls and
sumof shadows created a complex output determining the most appropriate locations
for growing vines.

14. Analysis of direct sunlight
Direct
sunlight in its
summary

sum of

factors

Direct
sunlight
(abstracted -
without
taking into
account the
impact of
cloud and
other
dynamic
components of weather) is expressed in hours of glare and average daily total solar
radiation Wh/m2/deň. Given the representativeness of the factor analysis was carried
out of direct sunlight in five key days (20.03, 05.05, 21.06, 07.08, 23.09) which is higher
optimization analysis result.

16. Forms of georelief
A separate part of the analysis was to analyze the forms of georelief, which is a
strong orographic factor, but its expression in our GIS analysis was highly
structured without opportunity of examination for impact of georelief forms to
quality of vineyard.

17. Conclusion
• Sample introductory analysis of spatial natural conditions Rača vineyard was limited time and
financial possibilities of the project, but nevertheless becomes a useful tool to protect
vineyards and sustainable development of urban structures in contact with the existing
buildings of the city. Usage of analysis in favor harmony of two conflicting functions
generates the perspective of optimalized settlement structure with the agricultural landscape
of vineyards. An obvious prerequisite for the wine business becomes integrated production
with optimal protection of the natural environment.
• The use of GIS technology in the Slovak wine-growing areas opens new possibilities for
evaluating the quality wine areas and creates a precise definition of the conditions for quality
classes of vineyards and their precise spatial destination. Obvious completion methodology
implied waiting for social order.
