Why am I not able to use the BDWA for ASTER, MODIS and other LP DAAC products on EarthExplorer?
LP DAAC data downloads are not supported through the USGS BDWA. The LP DAAC has a bulk download tool called DAAC2Disk and AppEEARS Please contact LP DAAC User Services for more information on downloading data via HTTPs.
How can I cancel my BDWA order?
Log into the Bulk Download Web Application, Select the Delete Order icon button to the right of the Order ID number you wish to delete
Do I need Java to run the BDWA?
No. This version of the Bulk Download Web Application uses the File System Access API natively within your browser instead of requiring a Java application installation. As a result, this is only available within Chrome-based browsers and Microsoft Edge. The browser will prompt you for permission to view and save to your file system but will only give the application access to the selected folder.
I receive a pop-up error message about permissions. What should I do?
Can I change location of destination folders in BDWA?
When initially entering the BDWA order, users can choose a destination folder. This folder will be the same for all of the files within the order and future orders. To change the destination folder of an order, click on the Destination Folder in the lower left corner of the window. This will change the destination of any new downloads that start after the folder change -- and that it will change the destination folder for ALL future orders it is responsible for keeping track of download directories they have used.
Is there a limit on the max number of products a user can request at one time through the new BDWA?
The limit is 10,000 products. In addition, it would be based on a user’s system and staging traffic on the EROS systems.
If I close BDWA while downloading continue?
Closing the BDWA will not stop active downloads. Active downloads will continue to download in the background. The BDWA cannot detect when the download completes, so upon restarting the BDWA, the active downloads revert to Available status. It is recommended to keep the BDWA window open until all active downloads complete. Closing the BDWA will cease initiating new downloads.
After receiving the USGS Online Bulk Download Order Confirmation order email and logging into the BDWA, I receive this popup message. Why?
There could be a delay in preparing the data for download. Depending on the data, it may need to be staged from tape drives. The order will say Queued while waiting. The order will say Available when ready to download.
Are there notifications for the status of the order?
The status notifications are: Bulk Download – Order Completion, Bulk Downloads – Retry Scheduled, and Bulk Downloads – Retry Cancelled
What do I do when the connection attempt has timed out?
You will need to work with your networking staff to ensure that there are no firewalls or network settings interfering with connections to <eebulk.cr.usgs.gov> on <port 4448>.
What if I could not read from server - “Read timed out”?
Try downloading the file again. If you have already tried downloading again without success, this could mean there is a permissions issue on the download server. In this case, you will need to contact USGS User Services.
How do I delete items out of my Item Basket on HDDSExplorer (HDDS)?
You will need to log on to HDDSExplorer with your EROS Registration System (ERS) account
Select Item Basket on the top right-hand side

HDDS Product Specification and Services Documentation
USGS Emergency Response strives to ensure that the disaster response community has rapid access to timely, accurate, and relevant geospatial imagery, products, and services before, during, and after a disaster.
During the course of a major disaster response, the USGS may receive a variety of imagery and related derivative products for the Hazards Data Distribution System (HDDS), a single point-of-entry system that provides preview and download access for disaster-related data. These data will often consist of imagery data, image maps, vector overlays, and other products that have been developed specifically for the means of supporting the disaster response.
In order to expedite delivery from data providers, the imagery data and contributed products may be transferred electronically utilizing the USGS Data Sharing Portal (DSP) services. Appropriate metadata for the imagery and contributed products will be required for accurate information and will assist in managing the products. As a result, products will become geographically retrievable on HDDS and shared across the response community.
The HDDS Product Specification and Services Document is a guide for DSP services and provides the specifications for the types of products and metadata that are required for HDDS.
Software and System Maintenance Downtime
The HDDS software and systems maintenance downtime is the 3rd Wednesday of each month. Notices are posted on the website. Normal downtime is from 7am CST to 2pm CST.
