Hi Alen, I tried to render your data with your SLD in GeoServer 2.18.5 and 2.20.0 because I was using almost the same technique, but on an 8-band Sentinel image. I encountered the same problem and even my data with my SLD didn't work anymore. I think a bug was introduced in the code, but I'm not able to identify it. I only noticed these lines in the log file:
org.opengis.parameter.ParameterNotFoundException: Parameter "Bands" is missing. at org.geotools.parameter.ParameterGroup.parameter(ParameterGroup.java:310) at org.geotools.process.raster.JiffleProcess.customizeReadParams(JiffleProcess.java:293) at jdk.internal.reflect.GeneratedMethodAccessor473.invoke(Unknown Source) at java.base/jdk.internal.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.base/java.lang.reflect.Method.invoke(Method.java:566) at org.geotools.process.factory.AnnotationDrivenProcessFactory$InvokeMethodRenderingProcess.customizeReadParams(AnnotationDrivenProcessFactory.java:897) ... I also found a simple workaround for you SLD, but sincerely, I don't know why referring to the first 2 bands before using the two you are interested in makes it work (I calculated the difference, but it doesn't matter: could be as well a sum) : <ogc:Literal> * diff = src[1]-src[0]; * dest = (src[3]-src[2])/(src[3]+src[2]); </ogc:Literal> Bye, Stefano On Sun, Nov 21, 2021 at 1:49 AM Alen Arturo Dioses Avellaneda < alen.dio...@gmail.com> wrote: > Good Afternoon > > I have problems trying to reproduce NDVI on the fly with jiffle on > GeoServer.
