How do I "stitch" two or more MODIS scenes together?

SeaDAS can merge your MODIS, SeaWiFS, etc. geolocated images as one by following these steps:

1) Load all your image files into the SeaDAS Band List selection widget.

2) Remap them using Seadisp->Functions->Projection, selecting "Extra Mapping Options" as Composite.

3) You may need to reset the Lat/Lon range (i.e. setting Longitude from 160 to -160 can merge images across the international
dateline).

4) The newly created band will be your merged composite.

Also, if you want to stitch MODIS L0 files that are consecutive granules you can simply concatenate them together. For example, if you downloaded two concurrent 5-minute granules from our site you could then simply:

   cat  MOD00.P2008106.2350_1.PDS  MOD00.P2008106.2355_1.PDS  >MOD00.P2008106.2350.PDS

If the MODIS granules aren't concurrent (e.g. two overlapping granules from two groundstations), then the CCSDS Merge tool available from the Dundee Satellite Receiving Station will do the job:
