Hi Jean:Export your excel file as a csv file. Then you can import the file and define the x and y fields. Then open processing toolbox and search for kriging. Select the tool and file out ghd parameters.Kirk SchmidtSent from my Galaxy -------- Original message --------From: jean Lukusa <luku...@gmail.com> Date: 2021-04-29 7:56 p.m. (GMT-04:00) To: Qgis Users List <qgis-user@lists.osgeo.org> Subject: [Qgis-user] Kriging using Qgis 3.18.2 Hi all.I have an excel sheet with xy coordinates and Au grades.So I want to create Au grade contour using Kriging method.How can I do it?Jean LukusaB.Sc.
