I have a csv file in which first column is longitude, second is latitude and third is temperature. However, the points are not at all equidistant i.e. for each pair of lat-lon I have a value. I want to convert it to 2D raster.
I tried with matlab (triangulation and griddata interpolation), but it was giving me 3D raster (surface).
Also, in ArcGIS I tried using XY data as x-lon, y-lat and z-temp but it was not showing georeferenced points. Is there any way ?
