How to request VRS Stand Count analysis
In order to calculate the number of plants in each zone with the same seeding rate, you need to have a variable rate seeding RX file (a VRS map), which is called VRS annotation in the Agremo app. The quickest way to obtain that file is to use yield maps from the combine harvester.
If you have already created a field and uploaded a GeoTIFF map, you can start reproducing steps to request VRS Stand Count analysis. Otherwise, you need to add a new field by filling in all the details requested in that dialogue or importing a field from John Deere Operations Center. Then, you will be asked to add a new map by uploading a zipped folder containing the GeoTIFF file from your computer or importing the file via a public link.
Importing VRS annotations
The Import annotation option is accessible through the Area tool where you can import annotation (KML/SHP file in a zipped folder) from the public link or your computer by clicking on the VRS annotation class button. The file should contain seeding rate data, otherwise, it couldn’t be uploaded.
When the VRS annotation is positioned on the map, there will be displayed different zones that are classified based on the seeding rate. You can either select the entire VRS annotation or only one zone.
Editing VRS annotations
Similar to other types of annotations, you can edit, copy & paste and remove VRS annotations and all these options are accessible via a right-mouse click. However, you cannot move or resize VRS annotations.
As for the editing options, you can change the Title field of the selected zone, and add comments and images.
Requesting VRS Stand Count analysis
When submitting the VRS Stand Count analysis, you can select one or more zones in the VRS annotation or the entire annotation. If you don’t want to analyze the entire annotation, use the Draw polygon option in the Area tool to draw the area you want to analyze.
In order to run an analysis, you have to fill in the mandatory fields: Analysis name, Crop type, Growing stage, and the comment section. The table of the zones is not editable and it shows the size of each zone with the same seeding rate, the percentage of the total area covered by one zone, and the seeding rate.
When the results of the VRS Stand Count analysis are ready, you will be notified by email as well as in the Stats bar on the right lower corner of the screen. Initially, the results for the whole annotation are displayed, but you can click on the specific zone or multiple zones and view the results only for chosen seeding rates.
Once you open the report in the Agremo app, you will see the map with the results on the left and the table in the right sidebar. The table shows the seeding rates for each zone which are predefined in an SHP file. As a result, it contains information about the number of counted plants on a zone level, the performance percentage, the size of the area, and the percentage of the total area.
To better view the map, you can turn off the VRS border and Result geometries from the Layers menu
What to do with the analysis results?
- Compare results with other analyses results on the same map or the results of the same analysis from different maps in one field.
- Share the results via email, export them to John Deere Operations Center or download them to your computer as a ZIP folder (it contains the PDF report, PNG image, and annotations).
- Use the Zone Management tool, Corn Calculator, or Biomass Calculator.
- Review the analysis results and leave us some feedback!
