I’m co-registering Sentinel‑2 L2A (10 m) with NAIP 2021 (0.6 m) over the Sacramento River; after warping both to EPSG:26910 in QGIS 3.34 with gdalwarp, I still see about 8–12 m drift along levee edges. What’s your go-to to preserve edge integrity and spectral values — anchor everything to NAIP with nearest neighbor, or do you fine-register with GCPs/OTB because we’re up against Sentinel‑2’s geolocation limits?
