Hi Mohd,Our level-2 data sets have not been projected to any particular coordinate system.Rather, the data are stored roughly in the order in which they were collected bythe various instruments such as MODIS.  To work with these data you will needto read the latitude and longitude data sets tha...

Hi Marat,There is the l3bindump program that is distributed as partof the processing code.  I use this program occasionally toread level-3 bin files into other packages such as GMT.l3bindump 3.0.0-r12992 (May 11 2016 19:30:27)Usage: l3bindump argument-list  The argument-list is a set of ke...

Slava,

You should be able to get to the next page now.  Thank you
for pointing this out.

Hi Slava,

I see the same bug... investigating.

Well, here is one inelegant way to get the corner coordinates you seek.  I am usingGMT in my example since that is what I am most familiar with, but the same logic shouldwork using any other map projection software like Proj4.# First, naively specify a Lambert azimuthal equal area projection wi...

Hi Jun,I had a look at the HICO scene you refer to and find thegeolocation information has no unexpected corner anomalies.I am attaching a 3-band image I made from the data withoutusing SeaDAS.  We'll need to investigate further.In the mean time, can you post the exact steps you usedto make...

Hi Bruce,

No official level-2 HICO products from our shop yet.
See this post.

We of the Ocean Biology Processing Group arealso relatively new to the HICO data stream.Since we are a small group, we appreciatewhen anyone from the science communitycalls out issues that we may not have noticedwith HICO (or any of our supported remotesensing platforms).  Please, continue to l...

Andy,When we first started working with these data, the coordinateswere often off by tens of kilometers.  Since then the HICO expertshave improved the geolocation considerably, but it is still notgood to within a pixel.My understanding is that it is very difficult to get accurate attitudeinform...

Hi Jasmine,When we first set up HICO processing here at the OBPG,we were inadvertently including a copy of the level-0data in the level-1B files we were making.  This substantiallyincreased the file sizes unnecessarily.  The /data/hicodataset is now no longer included in our L1B products.C...
