Tree Crown Delineation a New App to Monitor Trees




tree-crown-delineationThe latest drone app, Tree Crown Delineation automatically identifies individual tree crowns in your aerial survey. It also generates a geospatial layer of tree crowns with overall health level and crown diameter, as well as the mean vegetation index values.

Unlike other algorithms for row-based field plants, Tree Crown Delineation is a revolutionary tool for forestry and orchard professionals to monitor tree health.

The Tree Crown Delineation app assesses a tree’s health and physical characteristics from drone imagery. Results from the app contain summary statistics for three vegetation indices which  compare the health of individual trees and may reveal problem areas.

Tree Crown Delineation automatically identifies individual tree crowns in the survey. It also generates a geospatial layer of tree crowns with overall health level, crown diameter, as well as the mean vegetation index values.

Index values calculated include: RGB (GLI, VARI, NGRDI), BGNIR (ENDVI, GNDVI, GSAVI), RGNIR (NDVI, MNLI, OSAVI), Micasense (MTVI-1, LAI, GARI).

Inputs Outputs

  2. Tree Crown kml file

How does it work?

Once DataMapper automatically stitches drone imagery into a single orthomosaic map, the resulting Digital Surface Model (DSM) can be used to delineate tree crowns.  Areas of the DSM with steep slopes indicate a transition from ground to canopy, and this relationship is used to define the border of a tree crown. By applying vegetative index algorithms to the processed map, individual tree crowns can be assessed.

Who will use it?

The Tree Crown Delineation app is intended for orchard and forestry professionals seeking an efficient new way to monitor and compare trees. Historically, the only way to attain these characteristics was to physically enter the tree line and make qualitative observations. The creation of the app is in response to increasing industry demand for innovative data solutions that protect the long-term investment of trees which face a plethora of threats including insects, diseases, pollution, wind and ice storms.
