Viewshed Analysis For Designing A Sanitary
Landfill Site

Abstract
The idea of a location where waste is disposed causes prejudice to the residents
and the visitors of the surrounding area, no matter how strictly the sanitary
specifications are observed. Everyone realizes that most of these projects are
necessary for regional planning and development, however no one wants these
projects to be constructed near him/ her, especially when these projects are
visible and cause negative visual impacts that are permanent or present for a long
period. The selection of possible locations for an S.L.S. is based on technical and
financial criteria. GIS technology provides many useful tools to the planners of
such projects, which help them to take into consideration all the necessary
criteria and parameters in order to take their final allocation decision. This paper
presents the development of a process which was implemented in the design
phase of an S.L.S. in Polygyros in the area of Chalkidiki, aiming to determine
the viewshed before and after the activity is arranged, and to compare the
viewshed to the prevailing land use of the area, in order to draw conclusions on
the significance of the potential visual impacts. Viewshed analysis maps are
created, presenting the spatial distribution of the visual impacts and therefore
playing the role of a decision support tool.
Keywords: visual impacts, viewshed analysis, GIS, Sanitary Landfill Site.
1 Introduction
When designing a Sanitary Landfill Site (SLS) we take for granted, right from
the beginning, the fact that it will have a negative impact on the area of
deployment. The refusal from the part of the future neighbours with regard to the
