Stay Green

This analytic provides an automatic assessment of the ability for the crop to remain as a green growing plant late in the season.

1. Inputs and parameters

Stay green for field experiment:

  • RGB Orthomosaic *
  • Microplots*

Stay green for production field :




  • The analytic can be used when the plant senescence is starting (ex: R5/R6 for corn)

2. Deliverables

Stay green for field experiment :

  • Stay green %.gejson
  • Stay green mask.tif

Stay green for production field:

  • Stay green %.gejson
  • Stay green mask.tif

3. Attributes

Stay green % Geojson output for field experiment:

  • Attributes from the input vector file (parent_id, block_plot_id,… if the vector is from Alteia)
  • stay_green: Stay green % per microplot

Stay green % Geojson output for production field:

  • id: Id of the grid cell
  • id_x: column number
  • id_y: row number
  • stay_green: Stay green % per microplot

4. Workflow

  • Select the RGB Map and depending on the project, select the microplot vector or the filed boundaries.
  • Enter the grid size (Production field only). We recommend a grid of at least 1m
  • Launch

5. How to use the outputs

Open Inventory then Stay green subgroups of layers belonging to SURVEY DATA section on left panel. Stay green % per microplot is displayed under Stay green % layer, click it to open its information panel on right side to read value chart:

Stay green mask is under the same layer subgroup ; Value at point can notably be used to read value in any point of the map.
