How do I download data products and data sets?

Previous pageReturn to chapter overviewNext page

ODE provides four options for acquiring data products and data sets:


1. Search for products and directly download files from the product detail pages (more on using the product detail page)


2. Locate and directly download files from the Data Set Browser file listings (more on using the Data Set Explorer)


The next two options require that you first add the desired data products to the download cart from the search results list, product detail, or coordinated observation search results page.


3. Download HTML version of the product list from the download cart page, which allows download of individual files.


From the download cart page, expand the list of products selected for download. Check the "Display Individual Files of the Products" check box to see the individual files associated with each product. Then click the "Download HTML version of the product list" hyper link. This link will allow the user to save a local HTML copy of the product/file list displayed on the page. Then this results list web page can be used to view ODE product detail pages and directly download product files at any time. (more on using the download cart page)


4. Complete the checkout process. The Geosciences Node will acquire, organize, and then place the files in an FTP folder for your download.


After adding the desired data products to the download cart, the user will proceed through the "checkout process" by navigating to the Download page. Additional download options are available via check boxes on this page. The user may have the option to include “Selected Products’ Derived Files” with the cart selections. This will include map projected shape files and KML files for the products in the user cart. This option is only available if these files exist for the selected products. Also, the user can choose to add all the data set documentation and supporting materials for the products in the cart to the order by selecting the “Mini-Archive Files” checkbox, which creates a "Mini-Archive".


The next page of the checkout process requires the user to select the desired compression format (zip, tar, tar.gz) and enter his or her email address. The address is used to notify the user when the download request is available. The request will be submitted to a processing queue after the user submits the request on this page.


ODE will then create a set of compressed files that will contain all the requested products, derived files (if selected), and mini-archive files (if selected).. The compressed files will be placed in a user specific folder on a FTP site at the Geosciences Node. The user will be emailed a notification when the files are available for download. The email will contain the direct FTP address in addition to the login username and password.

The time between submitting the request and receiving notification that the files are ready for download varies based on the size of the request, and the number of other user requests in the queue. Small requests can be available within an hour or two, but large requests can take up to 24 hours. An estimate of the time required to fulfill the order is displayed on the Download cart page.


In addition to the options listed above, the user can navigate to the Geosciences Node site to download individual files directly from that location


Many ODE products are not stored at the PDS Geosciences node, but direct links to product files are available through ODE and these products can be added to ODE's download cart. Users can also acquire these data products directly from their host node websites - for example, HiRISE data is stored at the PDS HiRISE Data Node, CTX and MOC are stored at the PDS Imaging Node, and MCS is stored at the PDS Atmospheres Node.
