Removal of Line Artifacts

SyifaSukri

Hello everyone,

My gravity data has been previously levelled but I observe noises that could be line artifacts since they seem to be following the survey lines. I don't have the line levelling extension to use. Based on several references, this could be improved by applying directional cosine filter. However, the filter seems to affect the geological structures as well. Is there any other way to remove the noise? FYI, figure below shows the available extension.
