GIS in ecology Prepared by Kuchinskaia E.S. Group: E-M19-1-9 Checked by Fedorova N.Y.

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. GIS contain information on the spatial distribution of the data.

How data is organised in GIS How data is organised in GIS Spatial information is held in the GIS as a series of data layers

The creation of GIS helps in the formulation of hypotheses for tests or to make new suggestions for ecological exploration.

GIS calculations with using the formula of vegetation indices - NDVI, GNDVI and NDWI, Erkil crushed stone quarry, scale 1: 15000

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

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

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

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.

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.
