Aim
demonstrate the benefits of GIS technologies application in
environmental projects.
Objectives
• review the mechanisms of GIS
• reveal the possibilities of using GIS in ecology
• formulate the reasons why the use of GIS is beneficial in
the environmental issues management

GIS contain
information
on the
spatial
distribution
of the data.
As a result in a GIS it is
much easier to link
data within the tables
based on their spatial
relationships.

How data is organised in GIS
Spatial information is held in the GIS as a series of data layers
• data layers have the
attributes for each
record in them
• data layers have
information defining
the areas of the Earth
which they represent,
and the size, shape
and position of any
features within it.

GIS can be used for making measurements and carrying
out calculations that would have been harder to achieve.

10. New variables can also be calculated using GIS in that aspect and the slope of topography from altitude and elevation

information can be achieved.

11. GIS can be used to link data as needed for statistical analysis.

12. GIS is useful in the display of data because it provides essential information on collection of the data.

13. To summarize or why we use GIS in ecology:

• The creation of GIS helps in the formulation of hypotheses for tests or to make new
suggestions for ecological exploration.
• GIS can be used for making measurements and carrying out calculations that would have
been harder to achieve.
• New variables can also be calculated using GIS in that aspect
• GIS can be used to link data as needed for statistical analysis.
• GIS is also useful in the display of data because it provides essential information on
collection of the data.
Moreover:
• GIS technology allows you to receive and analyze data from remote and inaccessible
regions.
• GIS technologies allow the free use of data more than 20 years ago and guarantee their
reliability.
• Allows you to increase the speed of analysis of the studied objects, reduces physical and
time costs.
• Various calculation methods in geographic information systems allow you to analyze
territories of any scale and nature.
• They provide relatively high accuracy of the results and with the improvement of GIS
systems this accuracy will steadily increase.

14. Conclusion

The potential use of GIS systems now far goes beyond its
technical implementation. However, while GIS technology greatly
enhances decision-making capabilities, it does not replace them.
In a sense, it is both a “ toolbox” of advanced analysis capabilities
and a “sandbox” for visual presentation of the results. Although
GIS technologies represent an efficient technical tool for
deliberate regional planning, it requires a certain technical level
of the user. Nevertheless, as it was shown, GIS systems in
ecology are quite useful, and learning how to use GIS programs
is not as difficult as it might seem.
