Wrong .tfw file when exporting

Data Processing - Discussion and Q&A

Hi,

I have a problem when exporting the orthophoto because the received .tfw files looks something like:

        0.0417999756
        0.0000000000
        0.0000000000
       -0.0417999830
-12343654.0184000116
  3415626.8061000085

As you an see from the information, the X coordinate is wrong. You are exporting in UTM (my guess) but it is obvious that the X coord is wrong. It must be positive and less than 1,000,000.

Thanks for your help

Hi @luisarvayo,

Thanks for swinging by the Forum with your question. I’m sorry for the confusion here. I can confirm that the x coordinates are, indeed, correct for your map location. The reason why the longitude is negative is because your map was exported in WGS84 projection. However, you will want to export in EPSG 3547 (Web Mercator) projection for your map. Please give that a try and let us know how it works.

Best,
Stephanie
