Hi there,

I've been processing L1A files to L1B and L2. I want to produce a hi-res true colour geotiff from the L1B files. I can output hi-res ppm's using;

l1brsgen ifile=A...L1B_LAC geofile=A...GEO ofile=A....ppm outmode=2 atmocor=1 subsamp=1 resolution=250

This gives me a nice ppm hi-res.

I've tried using;

l1mapgen ifile=A...L1B_LAC geofile=A...GEO resolution=250 outmode=2 ofile=A.....tif atmocor=1 width=2000

to produce hi-res true-colour images. It will output a geotif but the resolution isn't as good as the ppm converted to png. I want to import the final tiff image into a gis software and I'm looking to have the best resolution possible.

Any suggestions or pointers would be a great help.

Cheers

Hi there,

I've managed to sort out my problem re my previous question by using l1mapgen but another problem had arisen.

I'm trying to use l2mapgen to generate a geotiff of a single parameter i.e. sst. I can generate a geotiff of Chl-a but when I try to do the same for sst
I get the Chl-a extent in the geotiff and not the sst extent;

example code: l2mapgen ifile=A***.L2  prod="sst" ofile=.A***.tif width=5000 outmode=3 threshold=0.1

I have displayed the data in SeaDas and there is sst data. I have tried the above code on both an L2 file I generated and a L2 file from the ftp with the same result.

Apologies for all the questions but this one really has me stuck.

thanks in advance

I needed qual_sst or qual_sst4 products to produce an SST geotif and neither came as default.
I used prod with l2mapgen to map sst.

thanks
