The vertical gradient function is particularly suitable for representing shorter wavelengths of gravity, typically less than 10 km. These two modeling methods were applied to the Great Meteor guyot in the Atlantic Ocean using its bathymetry. To optimize the computation of high-resolution gravity anomalies, the Armadillo, GSL, and OpenMP libraries were used to provide an environment for fast vector implementation, numerical integration for tesseroid calculation, and parallelization for loop iterations, resulting in a computation speed increase. The tesseroid and radial methods remain equivalent up to a resolution of about 1 min, with the radial method being faster when dealing with a large number of model points for the geoid. Aside from optimization enabling high-resolution gravity simulations, these fast modeling data can be used as the main operators in gravimetric inversion or to reduce the terrain effects in gravity observations, revealing gravity and sedimentary layers.<\/jats:p>","DOI":"10.3390\/rs16214031","type":"journal-article","created":{"date-parts":[[2024,10,30]],"date-time":"2024-10-30T09:10:44Z","timestamp":1730279444000},"page":"4031","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Efficiency of Optimized Approaches for Gravity Operator Modeling"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0009-0001-6352-8844","authenticated-orcid":false,"given":"David","family":"Fuseau","sequence":"first","affiliation":[{"name":"G\u00e9osciences Environnement Toulouse (GET), Observatoire Midi-Pyr\u00e9n\u00e9es (OMP), 31400 Toulouse, France"},{"name":"Centre National de la Recherche Scientifique (CNRS), 75016 Paris, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7007-3198","authenticated-orcid":false,"given":"Lucia","family":"Seoane","sequence":"additional","affiliation":[{"name":"G\u00e9osciences Environnement Toulouse (GET), Observatoire Midi-Pyr\u00e9n\u00e9es (OMP), 31400 Toulouse, France"},{"name":"G\u00e9osciences Environment Toulouse, Universit\u00e9 Toulouse III-Paul Sabatier, UMR 5563, 31062 Toulouse, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4504-0770","authenticated-orcid":false,"given":"Guillaume","family":"Ramillien","sequence":"additional","affiliation":[{"name":"G\u00e9osciences Environnement Toulouse (GET), Observatoire Midi-Pyr\u00e9n\u00e9es (OMP), 31400 Toulouse, France"},{"name":"Centre National de la Recherche Scientifique (CNRS), 75016 Paris, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1750-2819","authenticated-orcid":false,"given":"Jos\u00e9","family":"Darrozes","sequence":"additional","affiliation":[{"name":"G\u00e9osciences Environnement Toulouse (GET), Observatoire Midi-Pyr\u00e9n\u00e9es (OMP), 31400 Toulouse, France"},{"name":"G\u00e9osciences Environment Toulouse, Universit\u00e9 Toulouse III-Paul Sabatier, UMR 5563, 31062 Toulouse, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9809-6543","authenticated-orcid":false,"given":"Bastien","family":"Plazolles","sequence":"additional","affiliation":[{"name":"G\u00e9osciences Environnement Toulouse (GET), Observatoire Midi-Pyr\u00e9n\u00e9es (OMP), 31400 Toulouse, France"},{"name":"Centre National de la Recherche Scientifique (CNRS), 75016 Paris, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Didier","family":"Rouxel","sequence":"additional","affiliation":[{"name":"Service Hydrographique et Oc\u00e9anographique de la Marine (Shom), 29200 Brest, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8582-2553","authenticated-orcid":false,"given":"Thierry","family":"Schmitt","sequence":"additional","affiliation":[{"name":"Service Hydrographique et Oc\u00e9anographique de la Marine (Shom), 29200 Brest, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Corinne","family":"Sala\u00fcn","sequence":"additional","affiliation":[{"name":"Service Hydrographique et Oc\u00e9anographique de la Marine (Shom), 29200 Brest, France"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,10,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"138","DOI":"10.1007\/s13280-011-0192-y","article-title":"The Use of Bathymetric Data in Society and Science: A Review from the Baltic Sea","volume":"41","author":"Hell","year":"2012","journal-title":"AMBIO"},{"key":"ref_2","doi-asserted-by":"crossref","unstructured":"Mayer, L., Jakobsson, M., Allen, G., Dorschel, B., Falconer, R., Ferrini, V., Lamarche, G., Snaith, H., and Weatherall, P.
