Publications & processing help

The Global LAI project is still in its start-up phase. We presented first results from the project at the ATBC in Cairns, 2014. The presentation can be downloaded here: Pfeifer et al. 2014. We presented on mapping ecosystem functions in tropical landscapes at the Tropical Ecology Meeting in Goettingen, 2016. We also presented at the GFBI conference in Beijing, September 2017. The presentation can be found here: 2017_Beijing_GFBI

Protocols and templates for use in the field:

Protocol for sampling including setting the context. Pfeifer_2015_Protocol_LAI_Measurements_V3.0

Field recording sheet: here it is

Code (Matlab) & helpfile explaining code and more for processing images in the lab to derive canopy structure estimates: Code 1 (one exposure per sample point), Code 2 (three exposures per sample point). Both need this isodata file if you are using the Ridler and Calvard Thresholding as specified in the code. You can modify the code to add another thresholding algorithm. Here is the helpfile that shows the code, information on how to edit code and details the main CanEye steps as used in the Global LAI project.

Important: If you struggle to get the download to work from the CanEye project webpages ( (1) Go to Download tab, (2) Scroll down to Licence Agreement, agree and continue, (3) If you fail to read something in that licence agreement window: copy the agreement php listed there ( and paste into a new window of your internet search engine. That did the trick for us.
