Plant height

This analytic automatically estimates plant height for phenotyping or volume estimation in forestry.

The calculation can be done in two ways :

  • Subtracting a Survey 1 DSM whit a bare soil from Survey 2 DSM with vegetation

                or

  • Subtracting an estimated terrain elevation terrain from a Survey DSM with vegetation

1. Inputs

  • Basic scouting maps (DSM and NDVI if no DTM)
  • Estimated DTM from Bare soil model estimation analytic
  • Field boundaries

Plants should be taller than 50 cm ; overlap and sidelap shall be of minimum 80%

2. Output File Formats

  • .tif
  • .geojson
  • .shp
  • .mbtiles
  • .csv

3. Deliverables

  • Vegetation height map
  • Statistics at field / microplots level if option selected

4. Workflow

Step 1 : If you have no bare soil acquisition on a specific survey, you can modelize it thanks to the analytic “bare soil model estimation”. Please select the good category depending on your project (field experiment or production field) and then click on “bare soil model estimation”. 

  • Select the DSM of the survey in which you want to measure the height.
  • Select the scouting map or RGB map.
  • Depending on the type of project, select the “microplot” or “field boundaries” vector*.

*For Production field projects, field boundaries needs to be a vector file.

Step 2 : From the analytics panel list, please select Plant Height, and click on Launch

  • Select the DSM of the survey in which you want to measure the height.
  • Select the DTM (DSM) coming from bare soil acquisition or generated by the analytic
  • Depending on the type of project, select the “microplot” or “field boundaries” vector*.

*For Production field projects, field boundaries needs to be a vector file.

  • In case of production field, please select the grid size

5. How to use it

If you ordered “Plant Height”, two analytics appear on the analytic panel: “Vegetation Height” and “Vegetation Height statistics”


  • If "Vegetation height" layer is displayed, a map with a color scale appears: the highest vegetation is displayed in green. Low vegetation tends towards yellow or red. Clicking on “Value at point” gives the vegetation height in a specific location of the field

  • If "Vegetation height statistics" layer is displayed, the microplot or field vector appears. Clicking on a microplot gives statistics associated to this microplot.


Other color scale can also be displayed such as Mean, Min, Max
