Automated Decision Zones and Multi-Year Yield Analysis
What are automated Decision Zones?
Automated Decision Zones are zone sets created automatically using the most complete and recent data available to save time when creating VRS recommendations.
What data is used to make an automated Decision Zone?
An automated Decision Zone uses an ERU layer (where available), the most recent irrigation layer (if present) and the most recent MYYA layer (if present). If an ERU layer is not available, but an MYYA layer is, the Decision Zone will be built using the most recent MYYA layer, and the most recent irrigation layer (if present). For these layers, a minimum polygon size of 1 acre will be used.
When is an automated Decision Zone created?
An automated Decision Zone will be created when an automated MYYA layer is created, or when a crop is assigned to a field. The decision zone is created in the year that the crop is assigned or will be created in the next year if the automated MYYA layer is created after July 1 of the year. Example – harvest data for 2023 flows into Granular Insights in October of 2023. The data that flows in covers >80% of the field, so an automated MYYA layer is created. When that layer is created, it creates a Decision Zone layer for the 2024 season since it’s after July 1.
Also note that when an automated Decision Zone is created for a crop assignment, it will be set to active. If the automated Decision Zone is created from the automated MYYA, the zone set will be set as active automatically when the crop is set in the next season.
What if I don’t want to use the automated Decision Zone?
The manual zone creation process is still present, and you can choose to use whatever layers to create the Decision Zones you need.
What happens if I delete the Automated Decision Zone layer?
This layer will remain deleted. If new yield data flows in after July 1, a new Automated Decision Zone layer will be created for the next crop year.
Automated MYYA
What is MYYA?
MYYA stands for Multi-Year Yield Analysis. This process uses multiple years of yield data to analyze the overall productivity of a field. The output of this process is a layer with different polygons describing the productivity, with another layer providing a numeric index of how productive each area is relative to the others. Ultimately, this layer is used to help set yield goals and drive seeding rate recommendations in VRS.
What is automated MYYA?
The MYYA process has been automated, meaning that a MYYA layer will be created automatically, no longer requiring a manual, field-by-field process.
When will an automated MYYA layer be created?
Upon release, an MYYA layer will be created whenever yield data for a corn or soybean field that covers 80% or more of that field flows into Granular Insights. If data is post-calibrated or reverted to original source data, a layer will also be created.
What data is used to create an MYYA layer?
Any yield data that covers 80% or more of a field will be included. Consider this example:
- Field 1 has five years of yield data
- 2023 corn – 91% coverage
- 2022 soybeans – 93% coverage
- 2021 corn – 98% coverage
- 2020 soybeans - 68% coverage
- 2019 corn – 96% coverage
- The MYYA layer would include all the above data except for the 2020 soybeans harvest data, due to its less than 80% coverage.
How can I find and use an MYYA layer?
When you create a Decision Zone layer, the automated MYYA layer will be listed under the “Multi-Year Yield Analysis” layers list, named “Automated_MYYA_Class”.
What if I don’t want to use the automated MYYA layer?
The ability to create MYYA layers with the yield data you want is still present, allowing you to build layers like you have in the past.
What happens if I do use the automated MYYA layer?
If you choose to use the automated MYYA layer in your zone set, that layer will remain as-is, meaning no changes will occur to your MYYA layer from any automated processes (no updates to the automated MYYA layer when new yield data is loaded or existing data is post-calibrated, etc.)
What happens if there is new yield data that comes into the system?
If an automated MYYA layer is unused in any zone set, and new yield data comes into the system, the MYYA process will update the automated MYYA layer with the newest data. If that layer is part of a zone set, a new automated layer will be created instead.
What happens if I delete the automated MYYA layer?
If an automated MYYA layer is deleted, it will remain deleted. You can recreate the MYYA layer by using the manual creation process. A new MYYA layer will be automatically created when new yield data is uploaded, or existing data is post-calibrated or reverted to its original state.
What happens if I edit yield data?
If yield data is “post-calibrated” or otherwise adjusted, the automated MYYA process will respect that change and update the automated MYYA layer.
