The User Preferences Page allows you to control your receipt of email messages related to your orders, to indicate if you wish to include an archive header record with your data, and to specify your data extraction preferences related to AVHRR and GVAR data.
CLASS will apply the appropriate data file naming convention for delivered data sets based on the action
being taken and/or the user type. The mapping is as follows:
DS -- Anonymous user placing an order via the Shopping Cart
LDS -- User with access to restricted data placing an order via the Shopping Cart
LDS -- Subscription data being delivered (any user type)
Definitions for the data file naming conventions are as follows:
DS -- datasetName[.fileTypeExtension]
LDS -- lineItemNumber.datasetName[.fileTypeExtension]
The [fileTypeExtension] is defined as a combination of the extracted bands or channels and the user selected extraction format (minus the original extension, if any). For example, if JPEG image is selected for Band 2 of a GVAR_IMG data set, the [fileTypeExtension] of the delivered data set will be: .BAND_02.jpg.
The data extraction preferences apply to AVHRR data sets only. For any AVHRR data set you order, these preferences control which portions of the data you will receive and in what format the data will be provided. The preferences are as follows:
Once you have selected your User Preferences, click the Update button located at the bottom of that page.
A new "simple search" has been added to the search page for all data families. This by-passes the
shopping cart and allows the user to order data very quickly.
It is located at the bottom of the data family search pages.
When this button is clicked, a page will appear summarizing the number of hits and volume of data that resulted given the user's search parameters.
From there the user can place an order for all of that data. The "Place Order" button as shown will provide the results of the "simple search".
Once you have selected "Place Order" you will be taken to a results screen like the one seen here:
If you select "Place the Order" you will receive a confirmation message and be asked to participate in a user survey.
The confirmation message will contain the confirmation number for your quick search order.

Searching for Data
Select the options based on the Selection Criteria available for the requested product.
Product Specific Criteria
Temporal Criteria - The temporal section allows you to specify the time range for your search. The default time range is set to the current day or the most recent 8 days, depending on the product. Table with valid temporal ranges for the AVHRR, DMSP, TOVS and ATOVS data families.
To select the desired time range, click the "Temporal calendar" icon to display a calendar with which you can select the start or end date for your search. You may also enter the start and end dates directly, using the indicated format .
Spatial Criteria - The spatial section allows you to specify a geographic region for your search. You can select the spatial coordinates for your search by using an intuitive Rubber Banding tool or by entering your coordinates directly. To select your coordinates via the tool, simply point, click, and drag the mouse to create a box for your search region. Once the box has been created, you may zoom in or out.
To adjust the size of the box, click on one of the eight perimeter squares along the box"s edges, and drag it to adjust the box size. If you would like to move the box to a different location while maintaining its size, click and drag the small square at the center of the box.
Note that the maximum allowable latitude or longitude range is 80 degrees.
Once you have specified all of your desired search criteria, click on the "Search" button at the bottom of the page. You will be provided with the results from your search in a "Search Results Page."
The Search Results Page displays the results of the search you requested based on the search criteria you entered. The format and functionality of the Results Page differ depending on which broad category of product type you searched upon.
There are two types of products available: ordered and browser.
Ordered Products encompass data types that are obtained from CLASS by placing an order and subsequently retrieving the data via FTP. Browser products are smaller in size and can be accessed only through the web browser.
Results for Ordered Products:
Results are displayed on a separate browser window in tabular form, a few to a page.
The number of hits can be found to the right, above the results table. Depending on the number of hits found, you may have more than one page of results available. To change to another page of results, you can go directly to a specific page by selecting the page number in the "Jump to" section. Automatically, you will be taken to the specified page. You can also use the "Next" and "Previous" buttons to go through the pages in sequential order.
The results table depicts specific information related to each hit. Additional details about a specific hit may be obtained by clicking on the View Details button for that hit. See below for details about the Details Page.
A hit may be placed in (removed from) your Shopping Cart by checking (unchecking) the box in the Shopping Cart column of the table next to that hit. You may use the SelectAll and DeselectAll buttons to automatically select or deselect a large number of hits. Note that there are limits to the number of items of each data type that you may place in the Shopping Cart. As a result, the SelectAll button may not place all of your hits in the Shopping Cart.
The Update button updates your Shopping Cart with any selection changes you have made. The Go to Cart button updates your cart while also bringing you to the Shopping Cart Page from where you can continue processing your order.
For applicable data types, a Generate Map button will be present. If you click on this button, a new browser window will be generated and will contain a map depicting the overlap between all of the hits shown on the current Results Page and the geographic region you used for your search. The color of each hits overlap region matches the color of that hit in the results table. All of the functions of this map window are described here. Maps are created with the Generic Mapping Tools (GMT).
If you have placed a number of searches covering different ordered product data types, links to each family's results page will appear to the left of the results table. Simply click on the family name to bring up that family's results page. You will see that a second link for each searched upon family is labeled (ASCII). This link will display an ASCII file showing all of your hits for that search along with the corresponding search criteria.
The top of the Details Page shows a table containing detailed information about the individual item.
For some data types, if a geographic search was performed, a section or sections depicting the overlap between the individual hit and your search region will be shown. You can click on the thumbnail image showing the overlap to bring up a full image Orthographic Map. All of the functions of this map window are described here. Maps are created with the Generic Mapping Tools (GMT).
The details of the temporal and spatial overlap are indicated to the right of the thumbnail map.
Depending on the data type, a Browse Image section may be shown. Thumbnails may be clicked upon to bring up full images. For some data types, the images may be manipulated according to the instructions provided on the Details Page.
Results for Browser Products:
Depending upon the requested output format for your particular data type, you will either be shown results displayed directly to your browser window or you will be shown a dialog box through which you may download the results file. For results displayed directly to the window, you may use your browser to save the results locally.
You may have multiple hits for your search, so be sure to look at the selection menu at the top of the results page. Choose the result you wish to view and hit the Go button to display that result.
If you performed a geographic search and chose "Plotted image GIF" as your output format, below the image you will see a display of the area depicted by the GIF image.
The Shopping Cart Page displays information about each data set you have chosen to order. The total number of kilobytes of data you are ordering is displayed. You may choose to remove any data set from your order by unchecking the box in the "Order" column of the Shopping Cart table. You may then recalculate the size of your order by clicking on the "Recalculate Size" button. Like on the Results Page, you may obtain more detailed information about each data set by clicking on the numbered button in the "View Detail" column of the table. This will bring you to the Details Page discussed earlier .
AVHRR data sets have more order options: Geographic Subset, Bits/Pixel, and Channel Numbers. As AVHRR data sets are placed in the Shopping Cart, the ordering preferences specified in the User Profile Page are applied. These parameters can be modified once the data set is placed in the Shopping Cart.
For TOVS, ATOVS, and AVHRR data items, you may choose to include an archive header record with each data item. This TBM or ARS archive header record includes information about the order parameters applied to that item.
If you have already registered, your email address from your User Profile will appear in the notification field near the top of the page. If you want notifications for the current order to be sent to a different address, enter that new address into the field.
You may also enter an Order Comment which will be included in your order notification emails.
Once you are ready to submit the order, click on the "Place Order" button. Note, if you are a new user and have not yet registered, there will not be a "Place Order" button. Instead, it will be a "Register" button, which will take you to the user profile screen to register. Once registered, you may continue with your order.
Order Status
The Order ListPage is displayed after you have clicked on the "Order Status" link on the navigation menu. The page automatically displays information about all of your orders placed within the past 168 hours. You may also choose to display information about a specific older order by filling in the order number and clicking on the "Submit" button. Additionally, you may enter some number of hours and click on the "Submit" button. All orders placed within the entered time frame would then be displayed.
There are also additional search criteria that may be used called "Oerder Type" and "Order Progress." Both of these are used in conjunction with Order Hours and Order Number. The Order Type selection will allow you to search for specific types of orders. Order Progress will be displayed when eith Single or Large orders are selected and let you narrow down the progress of an order.
The number of results displayed on a search can be customized by clicking any of the criteria located under the input form. The results range from 10 - 1000 and will limit the page to showing up to that number.
Please note that you may only view the status of orders that have been submitted under your user ID.
