As an important ecological factor, leaf area index (LAI) acquisition methods mainly include traditional damage measurement and information technology (mainly by remote sensing and lidar). But what are the specific acquisition methods recognized by the field? Especially based on remote sensing image and 3D point cloud.
Dear Jincheng Liu i suggest the following article that resume the direct and indirect methods for LAI determination:
Review of methods for in situ leaf area index determination: Part I. Theories, sensors and hemispherical photography (Agricultural and Forest Meteorology 121 (2004) 19–35).
Moreover, also this paper of Chianucci explores the use of canopy photography in forestry: An overview of in situ digital canopy photography in forestry (January 2020, Canadian Journal of Forest Research 50:227-242).
Dear Jincheng Liu, actually there are many experimental methods that highly depend on your satellite and also your study area. However, sometimes, authors develop an index that can be generally used. For example, you can see "
Evaluation of Sentinel-2 Red-Edge Bands for Empirical Estimation of Green LAI and Chlorophyll Content" by DOI: 10.3390/s110707063
they developed an index for LAI that is easily applicable for a site, no matter what specific area you are looking for.
