Greetings<div>I have 4 bands (B1;B2,B3;B4) all with values >0 except in a few pixels where I have nulls.</div><div>I want to create a layer where I have 1 if at least I have 1 number and nulls where I don't have a single value</div>
<div>I have tried this</div><div>if (B1>=0 || B2>=0 || B3>=0 || B4>=0, 1,null()) but I got null in pixels where I have information for at least 2 bands.</div><div>any tip on how can I do this?</div><div>Thanks</div>
