If the resolution you are using is not a clean multiple or does not have the same origin, you could resample to a specified resolution or common raster grid using the resample tool in ArcGIS/QGIS or R using bilinear interpolation for continuous data (or nearest neighbor for categorical data). <br></div></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sun, Feb 17, 2019 at 6:00 AM <<a href="mailto:rs-ecology-request@lists.uni-wuerzburg.de">rs-ecology-request@lists.uni-wuerzburg.de</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">Send RS-ecology mailing list submissions to<br>

Hello,<br>
I would like to re sample Sentinel 2 bands that have 10 meters spatial<br>
resolution to 20 meters resolution (red edge bands).<br>
<br>
Any suggestion how to do that?<br>
