So far I've been using r.neighbors to do this, but some colleagues and collaborators are using r.resamp.filter instead. I took a good look at each and made some tests to compare, but I am not sure what are the real differences between each. Has this been developed or discussed somewhere?</div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false"><span><span style="color: rgb(0, 0, 0); font-family: "Helvetica Neue", Helvetica, Arial, sans-serif; font-size: 16px;">My inputs are rasterized versions of points, lines, or polygon features.</span></span><br></div><div dir="ltr" data-setdir="false"><span><span style="color: rgb(0, 0, 0); font-family: "Helvetica Neue", Helvetica, Arial, sans-serif; font-size: 16px;"><br></span></span></div><div dir="ltr" data-setdir="false"><span><span style="color: rgb(0, 0, 0); font-family: "Helvetica Neue", Helvetica, Arial, sans-serif; font-size: 16px;">If it is better, I can bring a reprex here to discuss it more deeply.</span></span></div><div dir="ltr" data-setdir="false"><span><span style="color: rgb(0, 0, 0); font-family: "Helvetica Neue", Helvetica, Arial, sans-serif; font-size: 16px;"><br></span></span></div><div dir="ltr" data-setdir="false"><span><span style="color: rgb(0, 0, 0); font-family: "Helvetica Neue", Helvetica, Arial, sans-serif; font-size: 16px;">Best regards,</span></span></div><div dir="ltr" data-setdir="false"><span><span style="color: rgb(0, 0, 0); font-family: "Helvetica Neue", Helvetica, Arial, sans-serif; font-size: 16px;">Bernardo Niebuhr</span></span></div></div></body></html>
