I recently completed a large corridor project involving several dozen RTK GCP’s all with NAVD88 elevations. I now realize that the project was run with the input coordinate system of the GCP’s as well as the output coordinate system for the project set to EGM96. Is my output in a consistent coordinate system, or will I need to rerun the project to get meaningful elevations? I am looking for a vertical accuracy of roughly 6 inches. I would ultimately like my coordinates in NAVD88, and am aware that to do this, Pix4D currently advises using an arbitrary coordinate system with NAVD88 inputs. This is an option, but I would like to avoid reprocessing my project if possible.
Thank you in advance!
