Description | ||||||||
Crop type and acreage mapping play a crucial role in monitoring agricultural land use and making estimations of crop production. These maps provide detailed information about the agricultural species present in a specific area, including their extent, and growth stage at a particular point in time. Satellite images capture detailed data about agricultural areas, allowing for the identification and classification of different crops based on their spectral characteristics. By leveraging advanced image processing algorithms and machine learning models, crop types can be accurately determined. | ||||||||

Main processing steps | Before creating crop type and acreage maps, the initial step involves mapping the location of crops. This process utilizes machine learning-based classification models, incorporating inputs from various Earth Observation (EO) data sources such as vegetation and backscatter indices. In addition to EO data, non-EO data like local in-situ data and land use land cover maps are also incorporated. The resulting crop location maps are then combined with vegetation and backscatter indices, Digital Surface Models, existing crop type maps like ESA WorldCereal, and ground truth data. These combined inputs are then fed into machine learning models for the classification of different crop types. | |||||||
