Hello, I am a former Duke MEM and I’m trying to process some MERIS L2 FRS data obtained from the Ocean Color portal. Before retrieving the data I had the imagery subset to the Gulf of Mexico region. When viewing the image in Seadas (below)
the image footprint appears correct but when I use your MGET import HDF to ArcGIS raster tool, the image is shifted east and south when reprojected to NA Albers Equal Area Conic. I might have made the erroneous assumption that the original Ocean Color data were in WGS1984. One question, is the input GCS correct? I filled in the script output parameters to those of the seadas band file (below). Assuming that the input cell size in decimal degrees is 0.002727 and the final output should be 300m. Where am I going wrong? Also, I thought the L2 Rrs was a unitless value from 0-1 but from the band info that isn’t the case. I appreciate any assistance you can lend to set me straight.
