ADDE - Getting Started

1. Start a McIDAS session.

   At the Unix prompt:

   Type:  mcidas

   Your session should still be set for six frames from the last time you changed the settings in the Configuration GUI. If not, set it for six frames, as described in Getting Started.

2. Log on to the workstation.

   Type:  LOGON initials project I

3. List your client routing table's groups and associated server IP addresses.

   Type:  DATALOC

   If this is the first time you are using the ADDE, the table is empty and the following listing is displayed.

   Group Name Server IP Address -------------------- ----------------------------------------

4. Modify your client routing table so that commands requesting data from a dataset in the group BLIZZARD are routed to the SSEC remote server with the IP address 128.104.109.190.

   Type:  DATALOC ADD BLIZZARD 128.104.109.190

   A listing similar to the following is displayed. The last line informs you that commands requesting data from a group with the Server IP Address <LOCAL-DATA> are routed to the local server.

   Group Name Server IP Address -------------------- ---------------------------------------- BLIZZARD 128.104.109.190 <LOCAL-DATA> indicates that data will be accessed from the local data directory.

5. List all datasets in the group BLIZZARD.

   Type:  DSINFO ALL BLIZZARD

   The following listing is displayed. The NumPos value is the number of positions in the dataset.

   DSINFO ALL BLIZZARD Dataset Names of Type:  IMAGE in Group:  BLIZZARD Name NumPos Content ------------ ------ -------------------------------------- G7-IR-4K 3 Storm of the Century G7 IR G7-VIS-1K 1 Storm of the Century G7 1K G7-VIS-4K 3 Storm of the Century G7 VIS G7-VIS-FD 1 Storm of the Century G7 16K IMAGES 14 Storm of the Century All Images M3-IR 3 Storm of the Century M3 IR M3-VIS 3 Storm of the Century M3 VIS Dataset Names of Type:  POINT in Group:  BLIZZARD Name NumPos Content ------------ ------ -------------------------------------- OBS 5 Storm of the Century Observational Data PTSRCS 5 Storm of the Century Point Source Data SFCHOURLY 1 Storm of the Century Surface Observations SHIPBUOY 1 Storm of the Century Ship/Buoy Observations SYNOPTIC 1 Storm of the Century Synoptic Observations UPPERMAND 1 Storm of the Century Upper Air (Mandatory Levels) UPPERSIG 1 Storm of the Century Upper Air (Significant Levels) Dataset Names of Type:  GRID in Group:  BLIZZARD Name NumPos Content ------------ ------ -------------------------------------- GRIDS 5 Storm of the Century NGM Grids No Datasets found of Type:  TEXT in Group:  BLIZZARD No Datasets found of Type:  NAV in Group:  BLIZZARD DSINFO -- done

6. List all datasets of type IMAGE in the group BLIZZARD.

   Type:  DSINFO I BLIZZARD

   Note that instead of the full word, 'IMAGE,' only an I is used. Each parameter in DSINFO can be abbreviated with it's first letter instead of writing it out in its entirety.

   The following listing is displayed. The NumPos value is the number of positions in the dataset.

   Dataset Names of Type:  IMAGE in Group:  BLIZZARD Name NumPos Content ------------ ------ -------------------------------------- G7-IR-4K 3 Storm of the Century G7 IR G7-VIS-1K 1 Storm of the Century G7 1K G7-VIS-4K 3 Storm of the Century G7 VIS G7-VIS-FD 1 Storm of the Century G7 16K IMAGES 14 Storm of the Century All Images M3-IR 3 Storm of the Century M3 IR M3-VIS 3 Storm of the Century M3 VIS

7. List all the images in the dataset BLIZZARD/G7-VIS-4K.

   Type:  IMGLIST BLIZZARD/G7-VIS-4K.ALL

   The following listing is displayed. The Pos value is the absolute position of the image in the dataset.

   Image file directory listing for:BLIZZARD/G7-VIS-4K Pos Satellite/ Date Time Center Band(s) sensor Lat Lon --- ------------- ------------ -------- ---- ---- ------------ 1 GOES-7 13 MAR 93072 17:01:00 26 87 1 2 GOES-7 13 MAR 93072 17:31:00 26 87 1 3 GOES-7 13 MAR 93072 18:01:00 26 87 1

8. List the two most recent images (positions 0 and -1) in the dataset BLIZZARD/G7-VIS-4K with expanded information on the available Band (1) .

   Type:  IMGLIST BLIZZARD/G7-VIS-4K.-1 BAND=1

   The following listing is displayed. The Pos value is the absolute position of the image in the dataset. The image in position 3 is listed first because it is the most recent image, relative position 0. The image in position 2 is the second most recent image, relative position -1... The Res values are the resolution of the images' center pixels.

   Image file directory listing for:BLIZZARD/G7-VIS-4K Pos Satellite/ Date Time Center Res (km) Image_Size sensor Lat Lon Lat Lon --- ------------- ------------ -------- ---- ---- ----- ----- ------------ 3 GOES-7 13 MAR 93072 18:01:00 26 87 Band: 1 0.65 um Daytime cloud detection 4.33 3.61 1337 x 1604 2 GOES-7 13 MAR 93072 17:31:00 26 87 Band: 1 0.65 um Daytime cloud detection 4.34 3.61 1336 x 1604

9. Create the aliases GV4 and GI4 for the dataset names BLIZZARD/G7-VIS-4K and BLIZZARD/G7-IR-4K.

   Type:  AKA ADD GV4 BLIZZARD/G7-VIS-4K

   Type:  AKA ADD GI4 BLIZZARD/G7-IR-4K

10. List the aliases in your client routing table.

    Type:  AKA

    The following listing is displayed.

    Alias Name Group/Descriptor -------------------- ---------------------------------------- GI4 BLIZZARD/G7-IR-4K GV4 BLIZZARD/G7-VIS-4K

11. Display the most recent image in the dataset with the alias name GV4. Display the image on frame 1 centered on Athens, Georgia, and draw a map on it. The AKA listing in step 10 shows that the alias GV4 represents dataset BLIZZARD/G7-VIS-4K.

    Type:  IMGDISP GV4 1 STATION=AHN[V] SF=YES;MAP VH 2

    
    The brackets after the station indicate the data type of the station to look for. The brackets are useful for station ID's in which there are more than one city using the ID. In this case, [V] indicates to search for a VOR station with a station ID of AHN because the station ID AHN works for both Athens, Georgia, and Haines, AK, USA.

12. Assign the dataset name MYDATA/IMAGES to all of the areas available on your local workstation.

    Type:  DSSERVE ADD MYDATA/IMAGES AREA 1 9999 "ALL AREA FILES

13. Use the IMGLIST command to find five empty areas on the local server.

    Type:  IMGLIST MYDATA/IMAGES.4000 4004

    
    If data exists in this block of areas, move or delete the areas or use the IMGLIST command to find an empty block of 5 areas.

14. Assign the dataset name MYDATA/TEST-IMAGES to the empty block of areas.

    Type:  DSSERVE ADD MYDATA/TEST-IMAGES AREA 4000 4004 "Scratch areas for testing

    A listing similar to the following is displayed.

    Group/Descriptor Type Format & Range RT Comment ------------------------ ----- ------------------ -- -------------------- MYDATA/IMAGES IMAGE AREA 1-9999 ALL AREA FILES MYDATA/TEST-IMAGES IMAGE AREA 4000-4004 Scratch areas for testing

15. List the groups in your client routing table.

    Type:  DATALOC

    A listing similar to the following is displayed.

    Group Name Server IP Address -------------------- ---------------------------------------- BLIZZARD 128.104.109.190 MYDATA <LOCAL-DATA> <LOCAL-DATA> indicates that data will be accessed from the local data directory.

16. Create the alias TI for the dataset name MYDATA/TEST-IMAGES.

    Type:  AKA ADD TI MYDATA/TEST-IMAGES

17. List the aliases in your client routing table.

    Type:  AKA

    The following listing is displayed.

    Alias Name Group/Descriptor -------------------- ---------------------------------------- GI4 BLIZZARD/G7-IR-4K GV4 BLIZZARD/G7-VIS-4K TI MYDATA/TEST-IMAGES

18. List all the images in the dataset with the alias name TI. The AKA listing in step 17 shows that the alias TI represents dataset MYDATA/TEST-IMAGES.

    Type:  IMGLIST TI.ALL

    The following output is displayed because the dataset has no images.

    Image file directory listing for:TI IMGLIST: No images satisfy the selection criteria

19. Copy the most recent image in the dataset with the alias name GI4 to position 5 in the dataset with the alias name TI. Place Athens, Georgia, at its center. The AKA listing in step 17 shows that the aliases GI4 and TI represent datasets BLIZZARD/G7-IR-4K and MYDATA/TEST-IMAGES.

    Type:  IMGCOPY GI4 TI.5 STATION=AHN[V]

     

    Once again, the brackets are used in specifying the station because the directions were to place Athens, Georgia, the VOR station, at the center of the image.

20. List all the images in the dataset with the alias name TI.

    Type:  IMGLIST TI.ALL

    The following listing is displayed

    Image file directory listing for:TI Pos Satellite/ Date Time Center Band(s) sensor Lat Lon --- ------------- ------------ -------- ---- ---- ------------ 5 GOES-7 IR 13 MAR 93072 18:01:00 34 83 8

21. Exit McIDAS.

    Type:  EXIT
