Matawa is a tribal council that looks after 9 First Nation communities in northern Ontario. Their land covers an area more than twice the size of New Brunswick and is difficult to navigate. But they need to study the land to make informed decisions about its' future use. So they taught themselves drone technology and mapped all their communities at 1cm accuracy, in six months. It's an extraordinary feat and Sarah Cockerton, manager of the Four Rivers Environmental Group explains how they did it.
