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 ?

Basically, you'll need to accomplish two major steps, which are:

  • (i) import your data on ArcGIS and set an appropriate coordinate reference system:

Layers with same coordinate system should align/overlap but do not?

  • (ii) perform the interpolation and output to a raster:

Converting points to raster in ArcGIS?
