I am having some confusion regarding Re-projections. I am a beginner so please go easy. Thanks
Is Re-projection necessary?
How do I ensure I am entering in the correct re-projection data? The specific coordinates to which the project resides is near: 29.7787884375031, -93.9474410188081. Maybe someone can take a look and confirm which EPSG code I should be using for Re-projection. (For our main CRS, the Horizontal projection is: 32615 - WGS 84 / UTM zone 15N)
While on the subject, can anyone help explain re-projecting height? I have read on a few other posts that if a new Horizontal Re-projection is made, then I may not be able to stick with Ellipsoid.
What happens if we do not incorporate GCP’s?
Any help is appreciated. Thank you!
