I would like to convert Ellipsoidal height to Orthometric height in Python. I tried below:
import pyproj
EGM2008height = pyproj.Proj("EPSG:3855")
wgs84_ll = pyproj.Proj("EPSG:4326")
print(pyproj.transform(wgs84_ll, EGM2008height, 34.68016909181368, 38.31245226053967,100))
It gives this error:
> Traceback (most recent call last): File "bos.py", line 26, in > <module> > EGM2008height = pyproj.Proj("EPSG:3855") File "C:\Users\abt\AppData\Local\Programs\Python\Python37-32\lib\site-packages\pyproj\proj.py", > line 151, in __init__ > super().__init__(cstrencode(projstring.strip())) File "pyproj\_proj.pyx", line 86, in pyproj._proj._Proj.__init__ > pyproj.exceptions.ProjError: Invalid projection b'+vunits=m > +no_defs'.: (Internal Proj Error: proj_create: unrecognized format / unknown name)
I deleted 100 (as I use ellipsoidal height) and again same error. Any help?
