The Realization of the system of software for the calculus and for the monitoring of the electromagnetic pollution of high and low frequency , with open-source software: GRASS, VTK, PARAVIEW for linux.
The present job illustrates the realization of a system, for the monitoring of the 
electromagnetic pollution of high and low frequency.

The purpose of the plan is to develop  a method of territorial map,  the levels of 
electromagnetic field (radio frequency and ELF), based on the knowledge of the 
distribution of sources on the territory and for the attainment of following 
•	The Systematic knowledge of the values of electromagnetic field presents 
over a territory, showing eventual critical situations;
•	The Possibility of a preventive evaluation of the receptivity of 
environment at a site  regarding the installation of new systems.

The method is based on the use of three instruments:
•	 The Database of georeferenced  sources (systems of radio frequency and 
cellular telephony, electrodes);
•	the Models of evaluation  of the magnetic fields generate  from sources;
•	the Measures.

For the implementation of the described system they have been used Open-Source 
softwares for linux.

For the import and elaboration of the maps it has been applied to the use of 
Grass6.1-cvs on Debian distribution. With the use of Debian, they have been exceeds 
all the relative problems to you you to the dependencies between the packages that 
they constitute Grass.
For the calculus of the electromagnetic Fields and the Volume of respect, generates 
from the antenna (norm CEI  ), has been used the language of scripting TCL/TK, 
integrated in the VTK libraries .

The representation of the electromagnetic Field and the Volume of respect (norm CEI 
2), happens through geometric figures in 3D.
The obtained figures therefore come elaborated and exported in format vrml, for 
their visualization in Paraview.
All  three systems have been integrated, by scripts TCL/TK, in pages PHP, and  they 
have been visualized by appropriate windows of visualization.
