I tried several proposed ones by projfinder.com, but was not able to align your shape with the actual coastline. My guess is your data also requires a transformation, not only a crs assignment. However, you do not need to reproject your altitude raster data; you need to properly georeference your vector data. | |

Since your nc file has almost no metadata defined, c.f. terra::describe("us_output.nc"), wouldn't it be best to simply ask your co-author, who produced this file, in which reference system he was working? Somehow, I don't really see the point in guessing here.

| Oct 25, 2022 at 12:13 | comment | added | Agus camacho | sorry, I thought the answers would be innecessary after sharing it: I got it from a coauthor who created it, there is not more documentation than what is provided in the nc file. | |
| Oct 25, 2022 at 10:40 | comment | added | dimfalk | What about the other questions? :) | |
| Oct 24, 2022 at 8:46 | comment | added | dimfalk | Your alitude is fine, but your polygon seems to be stretched in all dimensions, so you should try to attribute the crs properly... Where you got this nc file from? Would you mind sharing also? If spatial reference is not provided in the file, is there some documentation available? | |

Your altitude raster is not actually a grid but sth that looks like a summary of your grid created by raster package? Check the content with e.g. Notepad++, just 1 KB in size.
