Hi Victoria, Your image actually shows but it is so dark that you can't see it. The average value on greyscale 0-255 is only 14.2
gdalinfo PM25_monthly_19971000.tiff -stats ... Metadata: STATISTICS_MAXIMUM=169 STATISTICS_MEAN=14.204098037538 STATISTICS_MINIMUM=1 STATISTICS_STDDEV=8.2208826615229 Quick and dirty fix is to rescale image with GDAL and stretch the beginning of the scale 0-40 -> 0-255 gdal_translate -of GTiff -co tiled=yes PM25_monthly_19971000.tif scaled.tif -scale 0 40 0 255 Proper way with Geoserver is to publish the image through a SLD that does the stretch on-the-fly. I would guess that ContrastEnhancement Histogram could suit for this image http://docs.geoserver.org/stable/en/user/styling/sld-reference/rastersymbolizer.html -Jukka Rahkonen- VictoriaH wrote: > > Thanks for helping Andrea, > > I have two files to download by FTP: > > The first one displays correctly in the Layer Previewer and in my OpenLayers > based website: > > ftp://edacftp.unm.edu/outgoing/pub/bhudspeth/20140709.tif > > > The second one will NOT display in either..... > > ftp://edacftp.unm.edu/outgoing/pub/bhudspeth/PM25_monthly_19971000.tif > > Thank you! > > > > -- > View this message in context: http://osgeo-org.1560.x6.nabble.com/Why-do- > some-Geotiffs-not-display-as-Geoserver-layers-tp5164850p5165363.html > Sent from the GeoServer - User mailing list archive at Nabble.com. > > ------------------------------------------------------------------------------ > Meet PCI DSS 3.0 Compliance Requirements with EventLog Analyzer Achieve PCI > DSS 3.0 Compliant Status with Out-of-the-box PCI DSS Reports Are you Audit- > Ready for PCI DSS 3.0 Compliance?
