Next Steps

Improving the model

The published results from the Scottish Crop Map 2019 come from the first iteration of the machine learning model. Work will continue to improve the model in light of the limitations discussed in this paper.

The next step is to start including other data sources into the model to provide different types of signal for each crop. This should help to improve the predictions for some of the crops we have already included in the model but allow us to include smaller crop types which couldn't be included in this first iteration.

There are a number of data sources we will start to incorporate soon into the model. This includes a day of cloud-free Sentinel-2 satellite images for Scotland and weather variables (including hours of sunlight, average temperature and rainfall).

More timely crop predictions

Looking forward we aim to produce predictions in a more timely manner. To support us in this we have produced a guidance document and worked to streamline our methods. We have also carried out preliminary testing of the current model to identify whether all months of radar images are necessary. Early findings suggest the Autumn months are not required for our current predictions.

Estimating production values and yields

Estimating production values and yields is an important step in the development of this project, as these could become more timely and granular than what can be supplied through the current method. We are looking to collaborate with other organisations on this work and include data such as soil and weather variables.
