aWhere Agronomic & Crop Modeling APIs

Enrich your app and help growers make the right decisions every day by building in powerful modeling capabilities. When your app can give better insight to what is happening on a field, farmers can better manage their day-to-day operations and week-to-week planning. aWhere’s platform is designed to empower exactly this sort of agronomic modeling and decision-driving.

The API currently supports a variety of growth stage models. Knowing which stage of growth a crop is in drives important decisions related to applying products, watching for particular kinds of pests or diseases, and ultimately planning for harvest. And these growth stage models leverage the high accuracy of Weather Terrain™ to calculate a very reliable measure of GDDs and provide the corresponding growth stage.

We are continually adding models and crops to this API. The API currently has the following Growth Stage Crop Models.

For more Crop and Model details use the APIs below.

Note: Using Models APIs requires that you use the Fields and Plantings APIs to store information, like crop type and planting date, in the aWhere platform.

▶ Get a List of Available Crops or a Specific Crop #

Models are designed for specific crops, and often specific types or varieties of crops. This API provides the list of available crops. When creating a planting record, you’re encouraged to specify the crop that is planted in the field using these records. | View Documentation


▶ Get a List of Available Models or a Specific Model #

Use this API to retrieve the list of available models, or if you know the specific model ID you can use it to get a single record. | View Documentation


▶ Get Model Details #

Every model has its own parameters and criteria it uses to calculate the results. This API will return those details; for the growth stage models currently available this API returns information about the crop stages that the model may return. | View Documentation


▶ Get Model Results #

Use this API to run a model and get its current results based on the data you’ve saved to the Field and Planting records. | View Documentation
