Link for FTP credentials sign up form is broken

Hi,

I was gonna try to deploy this locally to test out, but it appears that the link for the FTP credential sign up (https://harvestchoice.wufoo.com/forms/download-cgiarcsi-srtm/) in the README is broken. Is there another way to get access to the FTP to run the `importdata` command? Thanks for the help in advance!
