WebThe CCDC function in Earth Engine can take any ImageCollection, ideally one with little or no noise, such as a Landsat ImageCollection where clouds and cloud shadows have been masked. CCDC contains an internal cloud masking algorithm and is rather robust against missed clouds, but the cleaner the data the better. To simplify the process, we ... WebClassify CCDC segments based on their model parameters and ancillary data. Extract a land cover map for a specific date. Calculate land cover change between two or more dates. I provide example training data and CCDC coefficients for seven countries in East Africa (Rwanda, Uganda, Ethiopia, Tanzania, Kenya, Zambia, and Malawi).
