ERROR: geogen_modis failed to produce a geolocation file

Thanks a lot Danny.

Yes, the L1A_LAC.x.hdf is extracted from the full file in ocean color browser. That's exciting for the SeaDAS 7.5 release, I will updated the lastest version and then try again.

Best,
Zhigang

l2bin and l3mapgen issues

Dear Don,

For those pixels in turbid lakes, they are easily taken as cloud or sunglint, I think these caused the HILT. Now, I have solved the problem of l2bin with the help of Danny.
