Gravity geologic method is one of the important to derive seafloor topography by using altimetry-gravity. and its committed step is gridding of regional gravity anomaly. Hence. we proposed a topography constraint factor weight optimization (TCFWO) method based on ordinary kriging method. https://www.kingarte.com/product-category/food-servicecommercial-kitchen-equipmentfood-preparation-equipmentcommercial-mixers/
