Data Products Search Tab - Search Page
You'll notice that when you open this page, there are a set of bars with a small down arrow. These bars can be expanded or contracted by clicking anywhere on the bar.
Notice the Reset Form button in the upper right? This clears all your search criteria. ODE saves your search criteria whenever you submit a search query. This allows you to use run a search and later come back to the same search. It also allows you to adjust the search criteria without having to reenter other search criteria. The Reset Form button clears all your search criteria at once.
. Entries containing observation time data are identified with the following icon: 
.
To select a product type, simply click in the box next to the type name. You may select one or more product types however you must select at least one before you may query ODE. Additional information on the data sets that contain these product types may be found in the "Data Set Description" link. Please note that CRISM is a complex instrument and ODE offers several specialized product type queries. If you are unfamiliar with CRISM data sets and are interested in CRISM data products, please review the "CRISM Product Primer", the "CRISM Product Description", and the "Suggestions on Finding CRISM Products" links before proceeding.
You may use the check boxes to select the desired products types to include in your search. Remember to use the Reset Form button if you want to clear all selected product types at once.
Step 2. Set Additional Filtering Parameters
This is an optional step of the product search. From this section you can filter results by product id, to a specific latitude / longitude range, and/or by a specific creation or observation time range.
Each PDS data product has a "Product Identifier (Product Id)". The product id is a permanent, unique identifier assigned to a data product by its producer. The product id is unique within a data set. The product id is a character string up to 40 characters in length. Many producers embed information about the data product in the product id. For example, the product ids of HiRISE data products include both the mission phase and the orbit number in which the data product was generated.
The "Select a Product ID or filter by a partial Product Id" field allows you to select an individual data product via its product id or, more commonly, select only those data products who's ids match a wildcard string. For example, you could limit your search to only those HiRISE data products that occurred during the Primary Science Phase of the MRO mission by entering PSP* into the product id field. NOTE: Using this field requires knowledge of the product ids and is for advanced users only! If you do not know the product id structure of the data sets you are interested in, please do not use this field. More information about the product id structure for data products in a particular data set can be found in the data set SIS.
Expand this bar and you will be able to filter your products query based on their center areocentric (Mars ODE) or planetocentric (Lunar ODE & Mercury ODE) latitude / longitude coordinates.
The areocentric coordinate system is a right-handed system with the origin at the center of mass of Mars. Areocentric latitude is the angle between the equatorial plane and a vector connecting a point on the surface and the origin of the coordinate system. Latitudes are positive in the northern hemisphere and negative in the southern hemisphere. Areocentric longitude increases to the east.
The Planetocentric coordinate system has an origin at the center of mass of the body. The planetocentric latitude is the angle between the equatorial plane and a vector connecting the point of interest and the origin of the coordinate system. Latitudes are defined to be positive in the northern hemisphere of the body, where north is in the direction of Earth's angular momentum vector, i.e., pointing toward the hemisphere north of the solar system invariant plane. Planetocentric longitude is measured around the equator of the body from a prime meridian defined and adopted by international agreement. Longitudes increase toward the east making the Planetocentric system right-handed. Radius is the distance from the planetary body's center of mass to the point of interest.
A warning will be displayed if data sets have been selected that do not have product center latitude / longitude coordinates. The message explains that no results will be returned for the listed data sets if coordinates are entered because the products will not match the search criteria.
The text boxes of this search option will only accept whole numbers. After all four parameters are entered, click the Refresh Map Button to refresh the mini-map to show the selected area.
You may also filter your query by observation time or product creation time. An observation time query filters products by observation UTC Start and Stop time range. It will find products with an observation time within the specified range, and products with an observation range covering your query parameters. The product creation time query finds products that were created by instrument teams within the specified UTC time range.
You may filter by either a single value or a value range. If you enter just a single value in the first field, ODE will select products that start with the entered value. For example, if you enter "2007-11", ODE will return only products with an observation time that covers or falls in 2007-11-xxTxx:xx:xx. If you enter "2007-11-01T00.13.27", ODE will return only products with an observation period during that point in time. You may also enter a range by entering values in both fields. ODE will select products within that range, products that cover the range, and products that overlap the range.
A new optional feature of ODE is the ability to preview a summary of the search results before proceeding to view the search results in table or on the map. After entering your desired search criteria, click the "Preview Search Results Summary" button to view the results summary. Remember that a data set selection is required to preview the search results summary and to submit a query.
Once you have completed your selections and filters, you query ODE via the "View in Table" and "View on Map" buttons. "View in Table" will show your results in a Product Search Results page. "View on Map" will show your results on the map page. NOTE, only products that have areocentric (Mars ODE) or planeocentric (Mercury and Lunar ODE) locations will be shown in the map. This is, in effect, an additional query filter.
A warning will be displayed if more than 50,000 products match your selected search criteria. The message warns that you may experience a slow response time when viewing large query result sets on the map, but you can still proceed by clicking the desired view results button again.
