Hydro-flattening is the process of creating a LiDAR-derived DEM in which water surfaces appear / behave as they would in traditional topographic DEMs created from photogrammetric digital terrain models (DTMs).
Grapes, one of the most popular and delicious fruits, are rich sources of vitamin A, vitamin C, vitamin B6 and folate in addition to essential minerals like potassium, calcium, iron, phosphorus, magnesium and selenium.
Raisins are dried grapes/currants. However, unlike fresh grapes, they indeed are rich and concentrated sources of energy, vitamins, electrolytes, and minerals. On weight per weight comparison basis, 100 g of dried grapes hold 249 calories, several times more fiber, vitamins, minerals and poly-phenol antioxidants than the fresh grapes.
