Plant Count & Size: Guide

How to request Plant Count and Size Analysis

The Plant Count and Size analysis is made to classify crops per canopy/tree crown size.

Traditionally this operation (Categorizing plants by crown/canopy size) is done by foot scouting and visual inspection, which is difficult to make and often inaccurate. The idea behind this analysis is that Agremo users can adjust size filters and understand each category based on the canopy size and the number of plants.

Step 1. Selection the annotation

You can draw an annotation or several annotations manually with the draw annotation tool. Additionally, you can  Import annotation through the Area tool, where you can import annotation (KML/SHP file in a zipped folder) from the public link or your computer.

Importing annotation steps:

1. Open the map where you want to add annotations.
2. Click on the Area tool
3. Click on Import annotation.
4. Click on Import SHP/KML via the public link
5. Choose a file.
6. Click on the Import button.
7. Annotation will be imported.
8. Message appears – Success! Successfully created annotation.

Select the one you want to analyze once the annotation(s) are available over the map. You can choose one or more. Once selected, they will turn yellow.

Step 2. Choose the analysis

From the dropdown menu, you can choose Plant Count and Size Analysis. To run an analysis, you must fill in the mandatory fields: Analysis name, Crop type, Growing stage, and the comment section.

Step 3. Checking the results of Plant Count and Size

When the Plant Count and Size analysis results are ready, you will be notified by email and in the Stats bar.

Displaying of the results on the map:

  1. Each marked plant on the requested area of the map is presented as a circle.
  2. The surface of each circle is transparent, so the plant is visible within its boundaries.
  3. The color of each circle corresponds to the group it belongs to in the sidebar results display histogram section.
  4. When the user selects the classification method (area or diameter) and sets the slider as they see fit, within each marked circle, a number will be displayed showing the area in m2 (depending on whether the account is set to the metric or imperial system (ft2) or the size of the diameter in m (depending on whether the account is set to the metric or imperial system).
  5. For small plants, these values ​​will be shown in cm2 and cm when talking about the metric system or in inches and square inches for imperial. Small plants are all plants whose largest diameter is 100cm or 39.3 in (including the value 100 or 39.3)
  6. When it does not get the Size but only the number of plants, the display is the same as with the counting analysis (depending on which algorithm the analysis was performed, it can be dots, lines, or polygons)

The classification filter:

    1. “Switch type” button that allows the user to choose based on the “Area” or “Diameter” of the result plants, from which they will be able to categorize them in the second step further. Only one of these two options must always be selected.
    2. Histogram-type results filter, allowing the user to classify the plants into separate categories based on the option selected in the first step.

Plant classification:

  1. The classification option, Area (m2, ft2) or by diameter (m, ft), is a mandatory field, and one (only one) must always be selected. By default, on the first opening of the result Area option is selected.
  2. Histogram, like an option for the user to classify plants into three different categories, at the first opening of the results, the slider is set to  ⅓ for each group:
    1. Red  – which represents a small plant
    2. Yellow  – which means a medium plant
    3. Geen  – which means large plants.
  3. The minimum and maximum values on the slider correspond to the minimum and maximum plant size or diameter we detected when processing the analysis. By moving the green circle user can change the size of each group, and the following rules apply:
    1. Each threshold belongs to the group before it 
    2. By moving the slider, all the changes are updated in real-time

If the map conditions don’t allow size classification and analysis, you will receive only the result of the number of plants to the user.
