Fig. 1From: Modeling sub-boreal forest canopy bulk density in Minnesota, USA, using synthetic aperture radar and optical satellite sensor dataLocation of Minnesota, USA, pilot study area (black box) proximal to the Superior National Forest (SNF) and the Boundary Waters Canoe Area Wilderness (BWCAW) and Lake Superior. Here, we investigated the potential of mapping coniferous forest fuel density using satellite sensor data and ground data collected between 2015 and 2016Back to article page
