When I upload an raster with high nodata values, the way the raster is
displayed makes it so the main area is white and the borders are black.
Does anybody know how to fix this?
I am using Geoserver 2.7.4.
I looked into the SLDs a little bit. Normalize or histogram is not fixing
it. In the 2.8 Users manual for rastersymbolizer
<http://docs.geoserver.org/2.8.x/en/user/styling/sld-reference/rastersymbolizer.html>there
is more text that refer to supported algorithms such as
*StretchToMinimumMaximum* , this appears that it might work, but when I try
to use it does not validate my sld. I am thinking these algorithms are not
implemented in 2.7.x
Thanks,
Tom G
They are not implemented for 2.7.x (the give away is when you look in the 2,7 manual http://docs.geoserver.org/2.7.x/en/user/styling/sld-reference/rastersymbolizer.html)

Thanks Ian, this morning I tried using the element in my sld and that is working for me. With the element, you can specify a color for the “bottom” of the dataset, and another to specify a color for the “top” of the dataset. This is working because I choose ‘0’ as the bottom and ‘300’ for the top, so it is excluding my noData values which are something like -3.4e+38. I haven’t tested it yet on a non-panchromatic raster.
