Note: The guide should be used for a quick reference to assist user in initiating his/her data mining quickly. For detail information, please reference the S4PM-DME User’s Guide.
1) User starts by entering a username. Click “Enter” to continue.
2) Enter all required information for first time user. Click “Register” to continue. User’s registration information will be verified against a list of registered GES DAAC users. User will be contacted by S4PM-DME staff for password. Typically, the response time is from 24 – 48 hours.
3) First time user will have only one option – “Data Mining String Development Tools.”
“New” has been pre-selected from the pull down menu. Click on “Select” to continue.
4) Enter algorithm name. Select the satellite instrument. Select the number of input datatypes and the number of output datatypes. Click “Continue_Specify_Input” to continue.
5) Enter product coverage in seconds. Enter the number of trigger files needed before the algorithm starts processing. Select the datatype. Since only one input was selected in the previous screen, the required/optional trigger button is automatically selected. Click “Specify Output” button or “Specify Advanced Input Options” to continue.
6) Selecting the “Specify Advanced Input Options” button gives you a choice of creating a time slide for the input data. Click “Specify Output” to continue.
7)
Selecting the “Specify Output” button gives the
user a choice of either tarring all output or specifying algorithm output file(s).
Select “Output only the files specified below.” Enter “Output Datatype
name”. This is used by S4PM. Enter “File Name” that is generated by user
algorithm. Enter the size of your output file. Click “Create
String” button to continue.
The ftp pickup area will use the Datatype_Name in the first field of the file
name.
i.e. MODIS06_L2.A2005185.0900.001.2005231143922.hdf which is a copy of the (…)
dgp_MODIS06_L2.hdf file that was created by the algorithm.
8) Upon successful creation of the data mining string, the user has options a) to return to main data mining page, b) to go to further development of algorithm or c) to logout. Click on “Mine Home” button to continue.
9) “Mine Home” now has the user’s newly developed string. More buttons have been added. The user has options to either delete the selected algorithm (not implemented) or view the data directory. Select the newly developed string LPHAM-NORRISTEST, to upload, build and install the algorithm. Click “Select” to continue.
10) The user is ready to upload his/her algorithm source. This sample algorithm requires 8 source files. Enter 8 source files and click “Select” to continue.
11) Browse and select all the sources from your local host (i.e. your desktop). Select “Source” or “Parameter file” for each of the upload files. Click “Upload Files” to continue.
12) Algorithm source files were uploaded are shown. Since there was a static parameter file, click on “Provide Parameter File Info” to continue.
13) Enter logical unit name or mnemonic for the user’s uploaded, static, parameter file(s). This is the name your algorithm uses to read your static file (i.e. in c it would be the unit in an open statement). If your code does not require a logical unit name, any name will work. Click “Continue” to continue.
14) Result of successful uploads. Click on “Development” to continue.
15) The user can upload more source files and repeat the above steps. Click on “Provide Build Information” to build and install the algorithm.
16) Select the algorithm’s compiler language. Select the source files to be compiled. Select “Compiler Options” and “Compiler Libraries”. Click “Generate Makefile” to continue.
17) Successful Makefile notification. The algorithm code is now ready for installation in theS4PM-DME environment. Click “Install” to continue.
18) The user should see the S4PM-DME processing steps. Upon receiving the “Passed” and “Successful Installation” messages (at the bottom), click “Search and Order Data” to continue.
19) At this point, the user has two choices, a) search and order data or b) put in a subscription request. Let’s take the first choice. Click on “Data Search and Order Request” to continue.
20) Select your algorithm. Enter the start/end date for your data. Enter the time for your data. Click on “Search” to continue.
21) Result of the search is displayed. Click on “Order Data” to continue.
22) If everything was successful, the user will see a similar web page. Data from the archive has been ordered. User should receive an email within 24 hours with directions on how to pickup his/her processed data from the previous calendar day.
23) Let’s assume user wants to place a subscription. As new data are ingested into the Goddard DAAC’s archives, S4PM-DME automatically processes your data. Click on the “Subscription Request” to input subscription parameters.
24) The user has a choice to add a subscription or to revise a subscription. Select “ADD Subscription” and click “GO”.
25) Select an algorithm for subscription processing. Enter the data start/end date. Enter the data start/end time. Select “Active” for the subscription status. Enter the subscription start/end date (start “tomorrow” and stop sometime in the future). Click on “Continue” to verify input and add more information.
26) User should see a summary of information to be submitted. Enter user’s email address and a short subscription message. Click on “Submit” to continue.
27) The user’s subscription request has been submitted to the ECS processing center. An operator will check and enter the user’s request. The user will need to wait 24 hours for the processed data e-mail.
