Dear EMLID community,
I am using REACH RS2 to collect ground control points for drone mapping and supporting monitoring vegetation after fire. Using also reach view 3. version 7.6.
I have collected data in LAT,LON (CRS EPSG 4326) and ellipsoidal height (m) and would like to transform it to another CRS. Target horizontal is EPSG: 25831 and target height is based on EGM2008 (EPSG 3855).
The horizontal transformation.
I have performed with sf package in R without problems but can be performed with QGIS and many other tools.
I know that I can choose the desired CRS when collecting the points but I thought that transformation is also possible afterwards. I wonder if someone has done the vertical transformation using emlid studio or one of the libraries in R or Python? And how my emlid reach RS is doing the transformation ? I would like to check with that value too.
A sample dataset is here:
Thanks in advance for any guidance.
