Hazards Disaster Data System(HDDS) via REDDnet

The AmericaView/REDDnet project is now mirroring EDC Hazards Data Distribution System (HDDS) data. At present, only the disaster_restricted data is available. The HDDS disaster_restricted password is required and must be obtained from Brenda Jones at EDC before accessing these data. Later, the non-restricted data will be added as well and will be accessible without a password.

Only HDDS data for current events are mirrored on REDDnet. At the time of this posting, 201001_Earthquake_Haiti, 200909_Samoa_Tsunami and 200909_indonesia_Earthquake are available.

To access HDDS disaster_restricted data via REDDnet, proceed as follows:
Use a web browser to navigate to: "https://se1.accre.vanderbilt.edu/lodn/"
Enter "RSWG" for the user name and the HDDS disaster_restricted password.
On the left side of the screen select: "disaster_restricted"
On the left side of the screen select the event you are interested in. for example: "201001_Earthquake_Haiti"
Continue navigating through the directories until you get to the data you want. The directory structure matches HDDS.
Click on any filename to download it. Allow the request to access your computer (necessary to write files to your local disk)
A Java Web Start window will appear. Select the Output file location and number of connections
(experiment with the latter for best performance. Numbers larger than 20 are sometimes effective. Optimal setting depends on network connection, CPU, etc.)
Performance should be up to 10 times faster than downloading from HDDS, but results will vary.
Please let me know how it works for you.
