[Geoserver-users] GeoServer color ramp doesn't work for Geotiff

GeoServer GeoServer User

Hello GeoServer List,

I am using GeoServer 2.4-SNAPSHOT on Ubuntu 12.10. I am trying to correctly
render a Geotiff in Geoserver. When I do a layer preview, the data is
rendered as grey scale. I have an SLD with the appropriate color definitions
as:

<RasterSymbolizer>
          <ColorMap type="ramp">
              <ColorMapEntry color="#000000" quantity="0.0" opacity="0.0"/>
              <ColorMapEntry color="#0000FA" quantity="1.0" opacity="0.1"/>
              <ColorMapEntry color="#FA0035" quantity="30.0" opacity="0.1"/>
          </ColorMap>
</RasterSymbolizer>

Transparency for the NoData Value of 0 works well, but I do not get the blue
to red color ramp that I expect. The gdalinfo output for the GeoTiff is:

Driver: GTiff/GeoTIFF

Dear W,
stupid question, did you select the style you mention as the default
style in the "publishing" tab for this geotiff's layer?

If so, can you share (even privately) a sample of the geotiff as well
as the sld?

Dear William,
I tested the (privately) sent sample data and it worked.

I suspect that you are previewing the data without specifing the correct style.
Either you set your style as the default one or you explicitly call it
using the style dropdown. If you don't specify your style as the
default one
the "raster" style will kick-in and it does very little that is:
- select a band, usually number 1
- stretch to 256 bits

The experience you are describing is compatible with this situation.

Let me know how it goes.

Simone Giannecchini

Thank you for your assistance Simone,

For the appropriate layer, under the 'Publishing' tab, and for the 'WMS Settings' -> 'Default Style' setting, I have selected 'PM2.5', which is the name of the SLD style I am referring the layer to (see below for code).
The small graphic under the 'Default Style' selection drop down correctly shows the red-to-blue color range, but a preview of the layer fails to show the correct styling that you sent me.

Ciao Williams,
can you change the log level to verbose send a request and then send
me the logs?

That said, can you tell me which platform you are working on and the
paster here also the exact information
about the geoserver version (look under "About GeoServer")?

Dear William,
I loaded the sample data + the style (not as default but as additional
style) in a standlone binary for geoserver
2.4.7 and ti worked for me.

You can find it at this link (in a few mins...):

Let me know if this helps.

The small graphic under the 'Default Style' selection drop down correctly

I suspect that you are previewing the data without specifing the correct

Either you set your style as the default one or you explicitly call it
using the style dropdown. If you don't specify your style as the
default one
the "raster" style will kick-in and it does very little that is:
- select a band, usually number 1
- stretch to 256 bits

The experience you are describing is compatible with this situation.

Let me know how it goes.

Simone,

Thank you for all your help on this. I discovered that I had set the null values in the raster to transparent both in the SLD file and in the layer settings page (i.e. InputTransparentColor). Once I removed the setting in InputTransparentColor, then I successfully achieved the desired effect.
