Direct kriging: A direct optimization based model with locally varying anisotropy

•We introduce a kriging model for curvilinear features in geoscientific objects.•Utilizing direct optimization enhances flexibility and adaptability.•It efficiently handles various constraints beyond limited variograms.•The model’s implementation is demonstrated using a genetic algorithm.•Efficacy i...
