Title
Forestry - Lidar: Quadratic Mean Diameter [Minnesota] {2019}
Description
This data is a Lidar-derived estimate of the quadratic mean diameter (QMD) at breast height in inches of the average tree in a stand. It was developed by the Minnesota Department of Natural Resources using Lidarthat was collected in 2019. The QMD is derived based on basal area per acre and stems per acre values (QMD = sqrt (basal area/number of stems*0.005454)). The QMDs were calculated for each of the 120 sample plots and the Lidarderived metrics for the plots were used as predictors to build a relationship (linear regression model) that was finally extended over the entire area of interest using selected Lidarpredictors at 20-m spatial resolution. This information can provide foresters a better understanding of the landscape and how it should be managed., Update frequency: None planned
