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://safeersappliancers.shop/product-category/aeg-ike84441fb-maxisense-78cm-touch-control-four-zone-induction-hob/
