Hi, I just started my master’s degree in Geodesy and we’ve just recently started using OSGEO, the task is to convert GRS-80 coordinates to EST97. I think I’ve got the parameters down, but I don’t know why it’s not converting the coordinates. Can someone tell me why? I attached a screenshot of the string as of right now:
echo 26.86657 58.355377 37 | cct +proj=lcc +lat_0=57.5175539305556 +lon_0=24 +lat_1=59.3333333333333 +lat_2=58 +x_0=500000 +y_0=6375000 +ellps=GRS80 +towgs84=0,0,0,0,0,0,0 +units=m +no_defs +type=crs
PROJ/GDAL have not migrated to this forum, so I think your chances of getting an answer are low now.
I’d suggest joining the project list and posting your topic there 
i got a solution from my professor, thank you regardless!

It would be nice to share the solution, for others reading this thread

Fair enough, the solution is the following:
echo 26.86657 58.355377 37 | proj +proj=lcc +lat_2=58 +lat_1=59.333333333 +lat_0=57.51755393055556 +lon_0=24 +x_0=500000 +y_0=6375000 +ellps=GRS80
