Coordinates disappear when exporting SAR data

[ABraun]

For most cases the “Range Doppler terrain correction” should be sufficient.

However ALOS Level-1.5 data is a bit tricky. Have a look here:

ALOS-1 L1.5 Terrain Correction

Dear users, The ALOS-1 L1.5 images are already map projected (GRD), but are not terrain corrected (orthorectified). All the SNAP tools in “Terrain Correction” or “Elipsoid Correction” do not work with the L1.5 images and give as error: “Source product should not be map projected.” So, how may we orthorectify those images using SNAP? Best regards, Gustavo

Alos 2 Geo-reference

Hi, thanks for the quick reply. I’m not sure if 1.5 NOT map corrected are an option? Too late to get different products anyways, we’ve already ordered and downloaded our quota for the year. I’ll investigate the Geomatica option for now. Cheers!
