I'm a python newbie.

I have a Geotiff file. I need to find coordinates in the Geotiff to find the position of a thermometer within the geotiff (the thermometer has the coordinates -115.47083484975207, 35.75837483423 e.g.).

I have these geotiff information:

PROJCS["NAD83 / UTM zone 12N",
SPHEROID["GRS 1980",6378137,298.2572221010002,AUTHORITY["EPSG","7019"]],

How do I transform the geotiff, so that I get coordinates in lat and lon? I have already tried this

But I don't quite know if this leads me to a solution. I just want to know how to find to position of the thermometer in the geotiff.

  • Your question is unclear to me. Are you trying to find the pixel coordinates (e.g., column 12, row 102) of the pixel in which your latitude, longitude coordinates fall? Or are you simply trying to convert UTM coordinates to latitude and longitude? – Arthur Nov 11 '15 at 19:14
  • Seems I cannot comment on your comment @Arthur so I am posting this as an answer (sorry, I am new here). Yes, the first one. I am trying to find the pixel coordinates in the geotiff (column x, row y) in which the lat/lon of the thermometer fall. – beginner123 Nov 11 '15 at 23:23

    Converting from map to pixel coordinates has been answered before: How do I get the pixel value of a GDAL raster under an OGR point without NumPy? – Kersten Nov 12 '15 at 8:07
