Subject: [Sea-mat] Matlab routine for Carter table correction
Message-ID: <s3bbb5c2.028@bsnw.nerc-bas.ac.uk>

Dear SeaMat people

Please find attached a Matlab program (carter.m), which corrects
single-beam echosounder depths using Carter's tables. (As you
undoubtedly know, most ship's echosounders assume sound
velocity to be 1500m/s, which is only very approximate.
Carter's tables were thus produced to enable a correction to
a more realistic depth, using an assumed mean sound speed 
that depends on latitude and longitude.)

The Matlab code reads two ascii files to find the appropriate
correction, BOUNDARY2.DAT and CORRECTN2.DAT - these are
also attached. Instructions on use of this program are in 
comment lines at the start of the Matlab code, so will appear
in online help.

Perhaps this code might be useful to the users of the SeaMat
webpage? If so, then by all means post it there. If you could
flag up myself as the originator of this code, that would be
useful.

Best regards
Mike Meredith

Hello,

I am trying to get an old program of Chuck Denham's to work: utminv.m 

(I know the m_map toolbox will convert from lat, long to UTM too, but my 
variables are really large and I run out of memory. )

Does anyone have a working version of utminv.m? 

Many thanks,

Amy

Does anyone have Matlab code for the Candela method for detiding vessel-mounted ADCP data that they'd like to share?
   Thanks.

I was wondering if anyone had MatLab code for opening XBT data that was 
created using the SEAS4 software?

Thanks.

Subject: [Sea-mat] datacursormode question
Message-ID: <200605031750.k43Hofpg011386@greenland.server1.odu.edu>

Several students here could use a method to graphically hand select outliers
in a data set. 

 

The 'datacursormode' seems to approach that capability but we haven't
conquered it. 

 

We need a function that will allow us to 'click' on a data point (as
datacursormode does) then put the index of that x,y point in a matrix. 

 

Help appreciated.

Hi Larry,

I've used the attached code to clean up time series data. I think it
could be easily modified to clean up other kinds too (like 2-D fields). 

I hope it helps.

Carlos

P.S. Although I'm not sure it would work, you might be able to use the
'UpdateFcn' variable in datacursormode in some clever way to write the
coordinates of the bad data to a file.
