Hi Andrea,
Thanks for looking into this.
Just tried replacing the arrow with circle graphic (as far as I understand
the suggestion) but still getting the same behaviour - ok with EPSG:4326
and blank results with EPSG:3857.
Please let me know If I got your suggestion correctly or should I try
something else.
I'm also attaching the SLD for reference.
Thanks much in advance,
Ivan
Hello All,
I'm using GeoServer for providing meteorological data through WMS. All
worked great so far but I'm now stuck implementing wind arrows layer.
The long story short: getting the data through WMS and EPSG:4326
projection works but does not work when requested through EPSG:3857
(Mercator) - it is returning only blank PNGs.
The same technique works for another (raster) layer I have.
The details:
GeoServer 2.7 with NetCDF store plugin and WPS extension.
Store:
NetCDF (NetCDF store plugin)
Layer:
Single banded (wind direction attribute only), Native SRS/Declared SRS -
EPSG:4326, default Tile Caching settings, Time dimension enabled.
Style:
RasterAsPointCollection transformation and single rule with
"extshape://narrow" graphics (rotation hardcoded for now). Could post the
entire SLD if interested.
So with the configuration above the arrows show in the Layer Preview but
not when I request them with EPSG:3857 projection (leaflet.js). I'm getting
blank PNGs only, there are no errors in the server log. As I just
mentioned above, the same configuration works like a charm for another
(raster only) layer where I visualize the wind speed.
I'm inclined to think that raster-to-vector rendering transformation can
only be requested in its native projection though I hope I'm really wrong
here or I'm just missing something.
Do you guys have any suggestion?
Hum, to rule out if it's the transformation, have you tried using a set of
/very) small
points instead of the arrows?
Cheers
Andrea
