You will need some reference from the CSV file to a spatial table to map it. All you seem to have is a id and a pollutant value. If Rstudio made the concentration contour it might be able to export a local reference system for each cell in the raster map. Another go would be to georeference your concentration contour map in QGIS. Then you can use it as a normal raster layer in QGIS.

  • the first numbers seems to be distance from point source in [m]. If i make points 50m - 100m - 150m... and than try to connect ID from csv with point ID. But it will be only on X axis and in circle...

  • We can't guess your data, you have to be as specific as possible about what you have and know if you want helpful answers. Jun 3, 2015 at 12:31
  • Rstudio writte conc.csv file with 9901 observation of 1 variable. Without spatial data. I guess its counts concentration each meter(first column) on X axis. And i dont know how to connect it with Qgis. You wanna see Rcode ?
