Methods
Having the previously listed datas, we used as a software for understanding this topic QGIS 2.18.3 Las Palmas. The methodology then used to investigate the hypothesis was to investigate in Vernier the relationship between greenness index noise-traffic pollution using the maps developped according to the recorded data.
To understand this local problematic a
grid was created on the map of Vernier to allow us work on a more local scale. To characterize the greeness index l of the all the grids components the
raster calculator has been used. It made possible the observation of the dispersion of values and permited us to calculate useful statistics (mean, median, standard deviation, etc.). The same methodology was used to calculate the same statistics, caracterizing each cell, on night-traffic noise and day-traffic noise.
Then Geoda (a spatial data analysis, geovisualization, spatial autocorrelation and spatial modeling software) has been used to remark and perceive some of the collected data facets.
