BBCH categories Straight from wikipedia https://en.wikipedia.org/wiki/BBCH-scale

Principal growth stages

  1. Germination, sprouting, bud development
  2. Leaf development
  3. Formation of side shoots, tillering
  4. Stem elongation or rosette growth, shoot development
  5. Development of harvestable vegetative plant parts, bolting
  6. Inflorescene emergence, heading
  7. Flowering
  8. Development of fruit
  9. Ripening or maturity of fruit and seed
  10. Senescence, beginning of dormancy
Being used here:
See updated multiple category classifications below
class value		 name description
0 Emergence First shoots and/or leaves are visible.
1 Growth State Plants have several distince leaves and/or tillers visible, but no visible tassels,flowers,or fruit.
2 Tassles or Flowers Plants have distinct tassels, flowers, or fruit.
3 Senescing 10% or more of visible plants are senescing.
4 Fully Senesced 90% or more of visible plants are senesced.
5 Harvested and/or Plowed Field Over 50% of the primary field has been harvested or plowed.
6 Snow Covered Field Over 10% of the camera field of view has snow.
7 Flooded Field Over 10% of the camera field of view has standing water.
8 Unknown The image is blurry, obstructed, or otherwise indiscernible.

On "Growth" being really broad. It could potentially be split into more categories, but they would be really ambiguous.

Bare soil cover would be really useful for sat sensors, but its hard to discern the bare soil cover from the oblique phenocam angle. Here transition to 100% green plant cover happens sometime in the Growth stage

Drop fallow/volunteers as a crop category. Really hard for me to tell and after ~8k annotations there are not many of them. Anything fallow is now unknown plant (0).

Dominant Cover

What is the dominant (50% or greater cover) component of the camera field of view?
During emergence or with volunteers plants can be present and noted in crop type and status while the dominant cover remains bare soil or residue. class		 name description
0 Unknown Blurry, water/snow covering lens
1 Vegetation Live or senesced vegetation
2 Residue Post harvest residue
3 Bare Soil
4 Snow any other non-grass planted crop
5 Water non-planted crop is present
6 none a harvested, plowed, or bare field. completely snow covered.

Crop Type

class name description
0 Unknown Blurry, water/snow covering lens
1 unknown plant Plants are present but cannot be confidently identified.
2 large leaf grass (corn/switchgrass)
3 small leaf grass (wheat/barley/rice)
4 other (soybean/alfalfa/cover crop) any other non-grass planted crop
5 fallow/volunteers non-planted crop is present
6 none a harvested, plowed, or bare field. completely snow covered.

Crop Status

3 Tassles/Flowering Plants have distinct tassels, flowers, or fruit.
4 Senescing/browning 10% or more of visible plants are brown/browning.
