[Qgis-user] Working with irregular magnetometry data points - converting them to an image

[Nicolas Cadieux]

Hi Calvin,

I see a lot of people have been corresponding.  I am an archaeologist and can help if you don’t figure thing out.  How many points are you looking at?  You could also use cloud compare to make a DEM.  I use Gdal grid with nearest neighbour for very big data sets.
