10 years ago Thats a good idea i have even implemented it before while developing the survey code. But I called it interleaved, like TV line scans.
About the circling on the edges of the survey, that will take some changes on AC code, but from what I understand the developers are already working on that. On Feb 17, 2014 5:29 AM, "ThorstenDP" notifications@github.com wrote:
