Before revision: Indirect methods of estimating LAI in situ can be divided in two categories: indirect contact LAI measurements such as plumb lines and inclined point quadrats indirect non-contact measurements Due to the subjectivity and labor involved with the first method, indirect non-contact measurements are typically preferred.
After revision: Indirect methods of estimating LAI in situ can be divided roughly into at least threeindirect estimation from remote sensing such as lidar and multispectral imaging categories: indirect contact LAI measurements such as plumb lines and inclined point quadrats indirect non-contact measurements Due to the subjectivity and labor involved with the first method, indirect non-contact measurements are typically preferred.
