I am interested in reprojecting MERIS L2 satellite imagery from NASA’s Ocean Color site. I have downloaded and installed BEAM, and am trying to use VISAT version 4.9 to reproject MERIS (L2) imagery (WGS 1984) and save the file as a geotiff. However, when I click the “reprojection” tool – I get the error message “Product (then my file location/file name [L2_FRS]) is not a valid source”.

Could someone please indicate how I can reproject these files?

Any help would be greatly appreciated,

Thank you kindly for your time,

Samantha Kerr

Hi Thomas and Samantha,

When I try to open a MERIS product downloaded from Ocean Color in the reprojection tool of Beam, I get the same error as Samantha. Also, when I try to import the image as an Ocean Color product, an error message appears which states that the selected product cannot be decoded. I think this is the same error message that would come up in older versions of Beam before Ocean Color products were supported. I know for Ocean Color SeaWiFS files, it helps to add the .hdf extension to the file before trying to import them as Ocean Color products. I tried this for Ocean Color MERIS products but it did not solve the problem. Do you have any suggestions?

Thank you for your help!
