Center Pivot irrigation is the primary agricultural method for growing crops in the Algerian Sahara desert. Drawing water from the Sub-Saharan aquifer, crops are planted, irrigated and harvested throughout the year. Potatoes, for example, are commonly grown throughout the region and are harvested in the month of August. When the crops are ready to harvest, the cells within the leaves above the soil stop dividing. This natural process, referred to as senescence, can be detected from space using red-edge spectral bands. Using a plant senescence reflectance index, crops ready to harvest are highlighted in dark green. Plants still in a growth stage are indicated in light green/yellow. Areas in orange indicate desert sand, where no crops are growing. The high resolution of Dragonette-001 also uncovers the faint outline of adjacent center pivots where crops have already been harvested, and are in the process of being seeded for the next growing season. #wyvern #hyperspectral #satelliteimagery #spacetechnology #smallsat

Cool run it through Satshot , segmenting the areas specifically by harvest and response .... Put some numbers in the game...for seasonal comparisons. Lanny Faleide
