Manually I use this procedure:</div><div dir="ltr" data-setdir="false">With a georeferenced raster in a UTM projection I use raster calculator to obtain a raster with all pixels set to zero. Then, with Serval plug-in, I manually set to 1 the value of the pixel in the wanted position (either by using a satellite overlay or by using a point vector layer with the appropriate coordinates). Then I use the proximity function under Raster>Analisys menu.</div><div dir="ltr" data-setdir="false">I want to make this via the Graphical Modeler, in order to be able to make the process fast and skip the manual introduction with Serval plug-in. At the very least, I need a mode to put the value 1 in the pixel of the selected null raster in the position givel by lat-lon coordinates. <br></div><div dir="ltr" data-setdir="false">Thank you!</div><div dir="ltr" data-setdir="false">Best,</div><div dir="ltr" data-setdir="false">Fabio Falchi</div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false"><div><p class="ydp3a68e8daox-fa029a8a82-default-style"><em><span style="font-size: 8pt;">USC - Universidade de Santiago de Compostela</span></em></p>
