[McIDAS #ORX-617145]: Getting full Lat/Lon in IMGLIST

MDS?  I am not sure what you are referring to; can you explain?

Ah Ha!  I guess by MDS you mean Mesoscale images...

One can use IMGPROBE to list the Lat, Lon of any point in an image, so
something like:

IMGPROBE LIST POINT MODE=N DAT=GOESRALL/M2C02 DAY=19071 TIME=21:05:50 
LINELE=1000 1000

should work, but I just found out that it doesn't.  The reason it doesn't work
is the inability to specify the DAY= and TIME= values on the command line
(I just checked the source code), and this strikes me as being a problem.

I then thought that if the image was first loaded, then one could use
IMGPROBE to list out the properties of the pixel at the specified LINELE
point, but this also didn't work for the GOESRALL dataset as this dataset
is an Archive dataset, and one needs to specify the DAY= for Archive
datasets.

I am left with the following: copy the image to a local dataset and
then use IMGPROBE on the copy.  Example:

IMGCOPY GOESRALL/M2C02 MYDATA/IMAGES.3000 DAY=19071 TIME=21:05:50 SIZE=SAME

IMGPROBE LIST POINT DAT=MYDATA/IMAGES.3000 LINELE=1000 1000 MODE=N

     Image Name           Day      Nominal Time   Scan Time    Band
  ----------------      -------    ------------   ---------    ----
  MYDATA/IMAGES.3000  12 Mar 19071   21:05:50      21:06:20       2

                        File     Nominal  Image     RAW         RAD         ALB 
        BRIT
       Lat/Lon      Line/Element  Line/Element                   *            %
 43:28:10/ 96:54:09   1000/ 1000    1001/ 1001           1597      232.98       
44.30         169
 *   watts/meter**2/steradian/micron

IMGPROBE: Done

And, 43:28:10/ 96:54:09 is 43.46944444 95.90250000

re:
> Thanks for your help in advance!

I hope that the above helped!

Cheers,
