Qualification And Provisioning Of Xdsl Broadband Lines Using A Gis Approach

Mavroidis Athanasios, Karamitsos Ioannis, Saletti Paola
2009 Zenodo  
The methodology used for interpolation is the Delaunay Triangular Irregular Network (TIN). This method is applied for a case study in ISP Greece monitoring 120,000 broadband lines.  ...  In this paper is presented a Geographic Information System (GIS) approach in order to qualify and monitor the broadband lines in efficient way.  ...  Triangular Irregular Network Delaunay was selected, as requires simplicity, provides economy and is a significant alternative to the regular raster of the GRID model.  ...
