I am working on a project that uses GCPs in NAVD88 and GEOID model GEOID18. GEOID18 is not an option for Pix4Dmapper, and the quality report states it that the output is in GEOID EGM 96.
Is my data being transformed to EGM96 even though my GCPs are in GEOID18 since PIX4Dmapper doesn’t have the option I need? And is there a workaround to avoid this? I need my data to match the GCPs I’m using.
PIX4Dmapper will respect your GCPs and align the outputs accordingly. You can set your vertical coordinate system to Arbitrary so that the quality report does not state EGM96. Ultimately, the GCPs will determine the elevations. Hope this helps.
