Traits Analytics

This article covers the following analytics :

  • Plant Height
  • Emergence Characterization
  • Flowering Characterization
  • Stay Green
  • FCOVER


1. Plant Height

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

1.1. Inputs

  • Basic scouting maps (DSM and NDVI if no DTM)
  • Optional DTM (bare soil)
  • If no bare soil survey is already available, an area of bare soil must be visible in the survey (such as alleys or tracks).
  • Field boundaries

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

1.2. Output File Formats

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

1.3. Deliverables

  • Vegetation height map
  • Extrapolated DTM if no bare soil option selected
  • Statistics at field / microplots level if option selected

1.4. Display

Open Inventory then Plant height subgroups of layers belonging to SURVEY DATA section on left panel. Enable Vegetation height layer, click it to open its information panel on right side to read distribution or show a value in any point of the map :


2. Emergence Characterization

This analytic automatically calculates the percentage of green (or leaves) to characterize seedling vigor — suitable for early stage crops. It is available for crops planted in rows, where bare soil is visible between the rows.

2.1. Inputs

2.2. Output File Formats

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

2.3. Deliverables

  • Emergence mask
  • Emergence % per microplot

2.4. Display

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

The Emergence mask belongs to the same layers subgroup :


3. Flowering Characterization

This analytic automatically calculates the percentage of flowering vs. no-flowering — currently suitable for row crops with yellow flowers only such as canola and sunflower.

3.1. Inputs

  • Basic scouting maps (RGB Bird View)
  • Boundaries of the field or microplots
  • Yellow flowers shall be visible from the sky

3.2. Output File Formats

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

3.3. Deliverables

  • Flowering mask
  • Flowering % per microplot

3.4. Display

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

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

4. 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.

4.1. Inputs

4.2. Output File Formats

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

4.3. Deliverables

  • Stay green mask
  • Stay green % per microplot

4.4. Display

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.


5. FCOVER

FCOVER, standing for Fraction of green vegetation COVER, is a measure of the fraction of ground covered by green vegetation. It quantifies the ratio between biomass and soil, i.e. the spatial extent of the vegetation. Values are between these two extrema :

0 = only soil

1 = we only see biomass

5.1. Inputs

5.2. Output File Formats

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

5.3. Deliverables

  • FCOVER per microplot (Fcover %)
  • Biomass mask (Fcover mask)

5.4. Display

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

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