Dear Author, I am a student and I would like to start my research in Road Network Detection using your dataset. I kindly ask you to share the dataset with me. My email address is: 2522067136@qq.com
We have scheduled a important maintenance operation for the Codalab public instance (http://competitions.codalab.org) for Saturday, September 8th.
The migration will start at approximately 9AM PST and should hopefully be completed by approximately 1PM PST that same day.
During that time the server will be down.
