[Geoserver-users] Can we change Raster dynamicly through "SLD_body"?

Kevin_Yang · June 21, 2007, 7:14am

Hello dear everyone,
I think I didn’t express clearly last time.I know we can display a WCS picture via WMS.If it is a Vector data layer,I can use “sld_body” to change its display style.But when I use the same way in a WCS layer,it didn’t display correctly.Cannot we use “sld_body” to change the Raster dynamicly which renders the WCS?The code I make is as follows which return no result.Thank you very much!
Best Wishes for you!
Sincerely yours,
Yang

Hi,

What do you mean by saying that your image did not display correctly? Is it that it is not processed in a way you want, or does it not even appear like the original one? I think that WCS is mostly for raster data exchange and it is not intented to do much image processing despite image format and projection transformations. I don't know what OGC Web Processing Service can do, but the name sounds like it might be something for you.

He wants to assign colors based on numeric values found in the
coverage by using a style.
