QField: "Preferred transform not available", where to place TIF file?

Hi. I am receiving the error message shown in the screenshot: “the preferred transform is not available”. The file it specifies is https://cdn.proj.org/us_noaa_nehpgn.tif which I downloaded. I tried using “import dataset” on it, and this gives no error itself, but does not resolve the original “transform not available” error. I tried putting the TIF file in the ZIP and opening the project from the zip, but I still get the error. My question is: where on the device does this TIF file go so that the transform will be available to QField?

Hi dto ,

Is this doc can help you? Altitude correction / vertical grid shift

Thank you, I used an android file manager to place the .TIF file in the correct location and no longer get the error message :slight_smile:
