Hi Sohail,
re:

Very good.

This should be easy: load an image; position your mouse cursor; and then run
the 'E' command.
Commands with a single letter in McIDAS can be run by typing the letter
and pressing the Return key, or holding down the Ctrl key and typing the
letter. The readout in the Text and Command window will show the location
of the cursor.

I think that I have figure out one way to run the ADT command. First I will
give you the high level overview of the steps needed, and then I will
include the commands and output that I got from running the steps.
1) start a McIDAS session that has at least 8 frames
I recommend starting a session with 15-20 frames that are at least
1000x1000 (lines x elements) in size.
2) create a local ADDE dataset for images in AREA format
We typically do the following:
DSSERVE ADD MYDATA/IMAGES AREA 1 9999 "All images in AREA format
3) find images that show a hurricane over several hours
Our GOES GVAR ingest machines, goeseast.unidata.ucar.edu and
goeswest.unidata.ucar.edu
are such machines, and they are open.
4) currently hurricane Maria can be seen in satellite imagery available on
goeseast.unidata.ucar.edu
The group name of the dataset to look at is EAST. Run DATALOC as follows:
DATALOC ADD EAST GOESEAST.UNIDATA.UCAR.EDU
Note carefully: the images you will you be using on goeseast.unidata.ucar.edu
will only be available for a limited period of time. The old images are
continuously replaced by newly ingested ones, so if you don't get to this
exercise in time, the interesting images will disappear!
5) find out what descriptors are in the EAST dataset:
DSINFO IMAGE EAST
6) take a look to see what images are available in the EAST/NH dataset
IMGLIST EAST/NH.ALL
7) display one of the thermal IR images centered over the Caribbean
and make sure that you can see hurricane Maria
IMGDISP EAST/NH.1 BAND=4 LAT=16 64 EU=IMAGE
8) verify that you know how to get the latitude and longitude of the
eye of hurricane Maria
Use the E command.
9) erase everything from frames 1-8 in your McIDAS session and restore
the IMAGE enhancement to each frame:
ERASE F 1 8
EU REST IMAGE 1 8
10) choose several images from the EAST/NH dataset that you will load
into successive frames in your McIDAS session
I would choose images that are about 3 hours apart from each other.
11) load the first image into the first frame; move the mouse cursor
over the eye of hurricane Marie; run the ADT command to analyze
the image writing the output into a history file named MARIA.ODT
12) repeat 11) for each time you are interested in and display the
image in a different frame
Displaying the images in a different frame is not absolutely
necessary, but it will allow you to create an animation of the
images later.
Also, ADT will want you to specify a local dataset into which it
will save the portion of the input image around the cursor location.
It is the local image that is analyzed by ADT
Here is the sequence of commands that I ran; I stripped off the output
from each command EXCEPT the IMGLIST one so that you can more easily
see the sequence:
IMGLIST EAST/NH.ALL
Image file directory listing for:EAST/NH

Comments:
- I have attached a GIF of the output from 'ADT PLOT MARIA.ODT'
command
- the key to doing the above is to position the mouse cursor over
the hurricane's eye at each step before running ADT
- the images that show Maria are real-time; they will not be kept
for very long
This means that you might want to copy the images to your own
machine for use later. Since the ADT uses infrared imagery
for its analysis, I would think that this would mean that you
would want to copy the Band 4/10.4 um images to a local dataset.
Here is an example of copying the first image used to the MYDATA/IMAGES
dataset:
IMGCOPY EAST/NY.1 MYDATA/IMAGES.3000 BAND=4 SIZE=SAME
- at this point, you know as much about how to run ADT as I do!
Cheers,
Tom
