Hello all,
I am trying to create a windbarb layer following the instructions in
this post:
https://geoserver.geo-solutions.it/edu/en/multidim/accessing_multidim/rtx/wind_barbs.html
I had successfully used this in the past, but I cannot get it working
with version 2.16.2. I have an older server with 2.13.2, there it works
correctly. I am not aware of any configuration differences between the
two. Could someone please verify if it is working correctly or am I
missing something?
Details about the errors I get:
I have converted a two-band GeoTIFF from a grib file, with u,v vectors.
This is published in a GeoTIFF layer and viewed through the Layer
preview OpenLayers map. If I add the style from the mentioned post I get
an error (see below). I have noticed that if I remove either the
interpolation or scale parameter from the RasterAsPointCollection
function in the sld, windbarbs are drawn.
best regards,
Gyorgy Tomcsanyi
