ENTERING A SEARCH: LOCAL GRANULE ID
A local granule ID applies only to data obtained from EOS platforms. It is a series of characters which provide important information about the granule to the EOS scientist. Local granule IDs are created at the DAAC where the data granule (and parent data set) originate. Because local granule IDs are used for EOS data sets only, local granule ID searches are sent only to EOS data servers (e.g. EDC-ECS, GSFC-ECS, NSIDC-ECS, EDC-ECS, and LARC-ECS). Note that an EOS data granule has both a data granule ID (See help page for Data Granule ID Search) and a local granule ID associated with it. The local granule ID contains more information about the data granule than does the data granule ID.
Local granule IDs have a specific format that is dependent upon from which EOS instrument the data is taken, and the data's science discipline.
1. Begin Search and Order Session
2. Search Creation: Local Granule ID Search
Click on Local Granule ID in the left-hand navigation menu under Search Types.
Select a Data Set(s) by clicking on the “Choose Data Set” button. In order for results to be returned, the Data Set chosen must match the Data Set of the Local Granule ID.
3. Search Form: Local Granule ID Search: Keyword Selection: Data Set
To narrow the Data Set list, you may type in a filter for a Data Set. For example, if you are interested in the ASTER DEM product, you can highlight ASTER Digital Elevation Model V002 and ASTER Digital Elevation Model V003 in the list given. You can also filter Data Sets by selecting the Data Center Name and click “Apply”. This may be helpful, given the large number of Data Sets that are searchable through the EDG.
Next, highlight the Data Set(s) of interest and click the OK! button.
4. Search Creation: Local Granule ID Search

ENTERING A SEARCH: DATA GRANULE ID
A data granule ID is a set of characters which uniquely identify each individual granule of a data set. Data granule IDs are created at the DAAC where the data granule (and parent data set) originate. Data granule ID has no standard format: it can range from the simple to the fairly complex. For example, a data granule ID for one granule from the Spaceborne Imaging Radar C-Precision is PR14435. A data granule ID for one granule from the MISR Level 1B2 Ellipsoid data set is SC:MI1B2E.001:252242.
The Data Granule ID Search is similar to the Primary Data Search, in that it provides results that contain descriptions of specific data granules from one or more data sets. Data granule descriptions typically include temporal and spatial coverage, data quality indicators, and physical storage information.
Data Granule ID searches can be done for both EOS and non-EOS data. Users of Data Granule ID Search must know the IDs of the specific data granules that they want. Note that not all data centers support Data Granule ID Search, so you may have to switch to Primary Data Search if the Data Granule ID search is unsuccessful.

2. Search Creation: Data Granule ID Search
Click on Data Granule ID in the left-hand navigation menu under Search Types.
Select a Data Set(s) by clicking on the “Choose Data Set” button. In order for results to be returned, the Data Set chosen must match the Data Set of the Data Granule ID.

First, run a search by clicking "ASTER " under the "Land" Discipline of the Primary Data Search Page. Highlight the Data Set of your interest (ASTER L1A RECONSTRUCTED UNPROCESSED INSTRUMENT DATA V002, ASTER L1A RECONSTRUCTED UNPROCESSED INSTRUMENT DATA V003, ASTER L1B REGISTERED RADIANCE AT THE SENSOR V002 and/or ASTER L1B REGISTERED RADIANCE AT THE SENSOR V003).
Choose the search area or if the granule IDs are known you may run a Data Granule ID search or a Local Granule ID search.
Next, add the desired granule(s) that you wish to have higher level products made to your Shopping Cart.
Click "Choose Options":
A list of the available Order Options will be provided for that granule:
*NOTE: The Order Options may vary depending on the ASTER granules and the available bands/telescopes (VNIR, SWIR, TIR). If the ASTER product you desire is not displayed under the ordering options for the granule(s) selected, the required bands/telescopes to make that product were not acquired. The ASTER table explains which bands/telescopes are required for each product. For an explanation of the higher-level ASTER Data Products, please see the ASTER Data Products Page.
For example, if you wanted an AST_07(ASTER On-Demand L2 Surface Reflectance) V003 Data Product to be created, you would click "Option 9".
Next, choose the Media Option (currently this is limited to FTP) and the processing options. If you are unfamiliar with the processing options, please refer to the ASTER Data Products Page.
Click "OK! Accept my choice & return to the shopping cart!".
Proceed to Shopping Cart: Step 2: Order Form in the SHOPPING CART section of this tutorial.
ASTER On-Demand requests ordered through the EDG and the ASTER On-Demand Data Gateway are currently available at no charge. The data resulting from these requests will not be archived in the EDG; please be aware of the expiration date given on the shipment notification email.
ASTER DEMs: Currently, only Relative ASTER DEMs are orderable through the EDG. If you are requesting the creation of an Absolute ASTER DEM (which requires at least eight Ground Control Points), you will need to place the order through the ASTER On-Demand Data Gateway at this time. For more information regarding the difference between Relative and Absolute ASTER DEMs, please see the ASTER DEM Product Description Page.
ASTER On-Demand products that are archived, such as routine Decorrelation stretch products, cost $55.00 per granule. Please see the LP DAAC Pricing Policy and/or the ASTER Pricing Policy for product pricing.

1. Result: Data Set Listing
If you ran a search based on more than one Data Set, the results will be displayed, along with the number of granules returned. To view a list of the granules, click the box in the “Select” column of one or more data sets and click “List Data Granules”.
*NOTE: If you searched for only one Data Set, you will automatically be transferred to #2 Results: Granule: Listing if granules are found.
2. Results: Granule: Listing
When the results are returned, you will see a table of granules. A granule is the smallest aggregation of data, which is independently managed in the archive. For example, one granule for Landsat data would be one Landsat scene (for example: one particular WRS-2 path and row for one particular acquisition date). In the Granule Identifier column, if there are two numbers listed, the first number is the Data Granule ID and the second number is the Local Granule ID.
For detailed information on a particular granule, click on “Attributes” in the Granule Information column. To view the pricing and media options for the granule, click on “Pricing” in the Granule Information column. If on-line data access is available, there will be a link(s) in the “On-Line Access” column (Data Pool). To view a resampled browse image for a particular granule, click on “Image” in the “Image Quicklook” column. You can also request an FTP browse image by clicking on “Sample” in the “Request Sample” column.
The “On-Line Access” column, when displayed, is a quick and easy way to obtain and view browses for data that is stored in the Data Pool. The Data Pool contains ASTER L1B REGISTERED RADIANCE AT THE SENSOR V003 over the United States and U.S. Territories and selected MODIS data that can cover the world. For more information on what Data Products are stored in the Data Pool, proceed to: http://LPDAAC.usgs.gov/tutorial/datapool_datatypes.asp
The Data Products available through the Data Pool may be limited due to limited space available for the Data Pool and Data Distribution Agreements with NASA.
