A companion R Shiny application for the publication Cohrs, C.W., R.L. Cook, J.M. Gray, and T.J. Albaugh. (2020). Sentinel-2 Leaf Area Index Estimation for Pine Plantations in the Southeastern United States. Remote Sensing. 12, 1406. link to article

Intended to give pine plantation managers in the Southeastern US a simple tool for assessing the LAI of their forests.

• Upload Sentinel-2 Level-2A Band 4 (red) & 8 (near-infrared)
• Upload shapefiles, representing an Area of Interest (AOI), e.g. either for single of multiple forest stands/sites; explore tabular contents.
• Calculate LAI for either the entire scene, or just clipped to the uploaded AOI.
• Export/Download LAI Output, clipped to the AOI that was uploaded by the user or the entire scene.

• Calculate the weighted, mean LAI for each individual observation/polygon within the uploaded AOI dataset; dynamically join to table.
• Add an "Export as CSV" button to download the tabular contents of uploaded AOI, with LAI calculations included for each row/observation/polygon.
• Add a "Save as New Shapefile" button to download the updated shapefile.
• Rendered plot interactivity (e.g. dynamically updating values as user moves cursor across the plot)
• A stand-alone, local desktop version is planned.
