HI @mcarvalho
The short answer is that there isn't native support for this in Alteryx. The GeoTIFF is a raster-based file where Alteryx spatial operations are vector-based. Here's a good summary of the differences:

In the data science blog post above, Sydney uses R packages 'raster' and 'rgdal' to read a raster file into Alteryx. I'm sure there are similar functions available in Python too if that works better for you. Either way, this article walks you thought the process so you'll know what to expect.
Check that out and let us know if there's anything the Community can help with.
