Mozambique 10 m resolution cropland map for 2017 to 2019

The classification was carried out on Google Earth Engine (GEE) platform using random forest classifier. Big data analysis and cloud computing techniques were employed for analysis of massive volume of multi-source remote sensing data and thousands of samples. All available Sentinel 2, and Chinese Satellite Gaofen-1 and 2 high resolution imageries covering Mozambique over the last 3 years were integrated for this research. Seasonal (dry season, & rainy season) composite, annual composite, composition based on percentiles, as well as greenest composite and other methods were applied to extract informative layers for classification. A variety of features collections such as spectrum, phenological, and texture information were jointly utilized for the 10m resolution national cropland mapping for Mozambique. The training of the classifiers was carried at both locally and nationally.
