[PROJ] How to transform XYZ to NEU

[Lesparre, Jochem]

Hi Lei,

Although some users have asked for this feature before, there is no specific PROJ functionality for this. However, you can do the transformation with cct if you use the right parameters:

Subject: [PROJ] How to transform XYZ to NEU

Hi,

I have the  coordinates of XYZ under earth geocentirc system. I would like to transform them to the NEU (North East Up) system which is a GNSS frequently used system.
Now I know the cct could do the transform XYZ to BLH:

echo 4097216.6805  4429119.0287 -2065771.3676 0 | cct -I +proj=cart +ellps=GRS80

47.2292116930  -19.0183060232     1552.9924        0.0000

But I do not know how to transform it to NEU. I also checked the documents, and find no answer.

Thanks


Lei
