I am converting multiple CSV (Lon, Lat, value) to GeoTIFF. My output is in a different projection (EPSG:404000) using 

output = 'gdal_grid -a invdist:power=2.0 -zfield "value" -of GTiff -ot Float64 -l %s %s %s' % (lyr_name, vrt_fn, out_tif)

I would like to convert it to EPSG:4326 using each of the following lines alone with no luck. Can I add something to my original output to set the correct projection?

output = 'gdaltransform -s_srs EPSG:404000 -t_srs EPSG:4326 -l %s %s %s' % (lyr_name, vrt_fn, out_tif)

outputSRS = 'epsg:4326'

output = gdal_translate -projwin_srs epsg:4326

    That's not valid Python code. And please state the actual result of your attempt. – bugmenot123 Jan 10 at 11:07
  • 404000 isn't a valid EPSG (or Esri CRS). Perhaps define it via its proj string instead? – mkennedy Jan 10 at 18:35
  • undefined epsg. This is a valid python code. I have a code that reads all csvs in a folder and converts them to .vrt and .tif. The line before last is the one i posted. – user2153702 Jan 10 at 21:10
  • I want to add something to the gdal_grid code to specify the epsg:4326. The alternative codes I tried, were post code but none worked. – user2153702 Jan 10 at 21:11

The problem is that your input file doesn't have a projection. The simplest fix is to tell gdal_grid what to use as the output projection - -a_srs epsg:4326.

  • like this? output = 'gdal_grid -a invdist:power=2.0 -zfield "value" -of GTiff -ot Float64 -l -a_srs epsg:4326 %s %s %s' % (lyr_name, vrt_fn, out_tif) – user2153702 Jan 10 at 21:00
  • i tried it and it produced .vrt files but no .tif files. – user2153702 Jan 10 at 21:03
