Aim : Create true colour RGB image from MODIS Level 1B
MODIS Level 1B
- Calibrated
- Not atmospherically corrected
Why
- Atmospheric Correction required for Chlorophyll Algorithms
- RGB image required in write up
Download data Reverb NASA
- MYD021KM.A2003359.1225.005.2003360215150.hdf
- MYD02HKM.A2003359.1225.005.2003360215150.hdf
- MYD02QKM.A2003359.1225.005.2003360215150.hdf
- MYD03.A2003359.1225.005.2003360210518.hdf
- MYD021KM - reflective bands at 1km
- MYD02HKM - reflective bands at 500m.
- MYD02QKM - reflective bands at 250m.
- MYD03 - geolocation’ information required by MODIS Oceans Level 2 (i.e., latitude and longitude) for any remapping.
I know all the above products can be generated from MODIS Level 1A, today I am being trying to be directed. and shall not investigate that area.
Interest link discussing how the different resolution reflective product work with the 1km resolution geolocation file. iCare MODIS_geolocation wiki
Tried to run l2gen from SeaDAS GUI --> Issue
Known and Fixed Issues
This should have been fixed I believe.
Reinstalled SeaDAS with all modules, --> Issue
Bugger will have to understand the command line.
Back one step
Let's try l2brgen - the gui is throwing NullPointerExceptions. in the good old AWT Event Queue
DId manage to reproject through the GUI which something
