Hi,

The lines that you are seeing are caused by the MODIS bow-tie effect.
See Figure 2.13 in http://modis.gsfc.nasa.gov/data/atbd/atbd_mod28_v3.pdf
or put your browser in full-screen mode and have a look at
http://oceancolor.gsfc.nasa.gov/MODIS/BowTie/ .
Moving your mouse over the fields in the lower right
labeled "133rd scan line", "134th scan line", etc. will
show you how pixels from adjacent scans overlap.

You need to map the data to remove this artifact.

Norman

thanks a lot for your reply..

I have to MAP?

mmm.. maybe is in data manipulation>> map proyction.. in L2.. I'm try.. but the images is still with lines and also rotate.

but again

really thanks for try to help, but i think y miss something..

Devoitka,

Yes, the Utilities->Data Manipulation->Map Projection is correct, but that should take out the lines, and it also should not rotate it, so maybe you are doing something different.
