Claim 14:
15. The one or more non-transitory machine-readable media of claim 9, wherein the operations further comprise:
determining that the geosignal value does not satisfy the first threshold;
based on the determination that the geosignal value does not satisfy the first threshold, determining whether a property value of the geosignal value is a local extremum; and
based on the determination that the property value of the geosignal value is not the local extremum, determining whether the downhole tool is near the formation boundary between a higher resistivity upper layer and a lower resistivity lower layer, or between a higher resistivity lower layer and a lower resistivity upper layer, based on a sign of the property value.
