I have the MODIS wor...

More questions on true color generation.The l3mapgen help page shows and example of using: rhos_670,rhos_555,rhos_412above says to use: rhos_469,rhos_555,rhos_645  (this generates a buddy brown that overlays the chlor_a, and sst data, but no clouds,water or land)I assume the numbers are frequen...

How to get higher than 1000m/pixel resolution?

Am I correct in noting the scaling ONLY seems to be applied when applying a pallet? ie: apply_pal=1. If I generate a grayscale image with apply_pal=0 like:l3mapgen interp=area 'projection=+proj=merc +a=6378137 +b=6378137 +lat_ts=0.0 +lon_0=0.0 +x_0=0.0 +y_0=0 +k=1.0 +units=m +nadgrids=@null +wkt...

Ok, thanks and fudge=3 really helped to eliminate the holes in the image.I have a question on the scaling, what is the math that is used for the linear and the log scaling?For example, is it based on the default data_min, data_max for a given product? such that if multiple shots are processed they a...

I'm not finding area_weighting as a parameter to any seadas commands. Did you mean average=area which seems to be available in l2bin?

Don, Thanks! Sounds like a great plan. I appreciate the additional education on this, as I'm more of a programmer/user of the data than scientist when it comes to the ins/outs of this. Thanks again!

How to get higher than 1000m/pixel resolution?

Ok, I got it working using the following steps. One question I have is on resolution.If l2bin resolution=250m, then I get holes in the final output image. The only way I could get a smooth output image was to set l2bin resolution=1km. Am I missing a parameter that would allow me to generate higher r...
