help in geocentric coordinates

[arafat]

Hello, rookie question

Is the geocentric coordinate system in meters? , I use the following function to get it but I don't know the unit 

Code: [Select]

chunk.transform.matrix.mulp(chunk.cameras[0].center)
if so can I compare between two different points using only X and Y to get the Euclidean distance between them in meters?

thanks in advance

Hi arafat,

you could look at chunk.crs.geoccs.proj4 and see units entry as in:

chunk = Metashape.app.document.chunk

chunk.crs.geoccs.proj4
Out[8]: 2022-01-31 06:51:50 '+proj=geocent +ellps=WGS84 +datum=WGS84 +units=m'

chunk.transform.matrix.mulp(chunk.cameras[0].center)
Out[9]: 2022-01-31 06:52:08 Vector([4776929.508012832, -109377.39947718395, 4211329.972593664])

as you can see  units are m and geocentric coordinates are in meter...
