1. Description

Estimates the percentage of flowering for rapeseed or sunflower

This article will cover the 2 analytics:

• Flowering characterization from orthomosaic
• Flowering characterization from reflectance

2. Prerequisites

Flowering Characterization from orthomosaic:

• RGB Orthomosaic*
• Microplots* or Field Boundaries‍* 
• Grid Size*

Flowering Characterization from reflectance:

• Raster reflectance map*
• Microplots or Field boundaries‍*
• Grid Size*

*Mandatory

3. Workflow

3.1 Flowering characterization from orthomosaic

Step 1 - In the "Analytics" tab, search and select "Flowering characterization from orthomosaic" and click on "LAUNCH".

Step 2 - Select the "RGB map" (orthomosaic) (1) and the "Field Boundaries" (2) (field boundaries vector or microplot vector) and click on "NEXT STEP" (3).

Step 3 - Define the grid size, for microplot skip this step.

Step 4 - Click on "LAUNCH FLOWERING CHARACTERIZATION FROM ORTHOMOSAIC".

Step 5 - Click on "FINISH" to leave the analytics.

3.2 Flowering characterization from reflectance

Step 1 - In the "Analytics" tab, search and select "Flowering characterization from reflectance" and click on "LAUNCH".

Step 2 - Select the "Reflectance" map (1) and the "Field Boundaries" (2) (field boundaries vector or microplot vector) and click on "NEXT STEP" (3).

Step 3 - Define/check the band name of the reflectance map and define the name of the output. 

Step 4 - Click on "LAUNCH FLOWERING CHARACTERIZATION FROM REFLECTANCE".

Step 5 - Click on "FINISH" to leave the analytics.

4. Status and Progression

Check in the "LAUNCHED" tab that the analytics is in progress

Aether will notify‍ the user that the analytics results are available.

5. Results

In the "Inventory" subgroup of "SURVEY DATA" a new subgroup  "Flowering Characterization" is created with 2 layers:

• Flowering mask

• Flowering %

6. Deliverables

6.1 Files

The analytics result files are located in the "Download"‍ section.
