GDAL kullanarak bir bant tiff'e renk tablosu nasıl eklenir?

1 bantlı GeoTIFF dosyam var. Bant için renk yorumu gridir. Benim dönüştürmek amacıyla bir renk tablosu istediğiniz Col.tiffTo Col.jpegya Col.png.

Bir .vrt aracılığıyla bu tiff bir renk tablosu koyarak çalıştı:

gdal_translate -of VRT  Col.tiff Col.vrt

daha sonra .vrt'yi ekleyin:

<ColorInterp>Palette</ColorInterp>
<ColorTable>
   <Entry c1="0" c2="0" c3="255" c4="240"/>
   <Entry c1="0" c2="0" c3="254" c4="240"/>
   <Entry c1="0" c2="0" c3="253" c4="240"/>
   <Entry c1="0" c2="0" c3="252" c4="240"/>
</ColorTable>

Ve tekrar tercüme et:

gdal_translate Col.vrt Col.tiff

Ama cevap verdi:

Warning 1: Unable to export color table to GeoTIFF file.  Color tables can only be written to 1 band or 2 bands Byte or UInt16 GeoTIFF files.

Nasıl yapabilirim?

Bilgi için, Band için gdalinfo var:

Band 1 Block=55x18 Type=Float64, ColorInterp=Gray
  Description = Something
  Metadata:
    GRIB_COMMENT=Something[p]
    GRIB_ELEMENT=TMP
    GRIB_FORECAST_SECONDS=0 sec
    GRIB_REF_TIME=1401926400 sec UTC
    GRIB_SHORT_NAME=SMTHG
    GRIB_UNIT=[p]
    GRIB_VALID_TIME=1401926400 sec UTC

gdal ile, gdal_dem ( color_relief ) tabanlı bir resmi renklendirebilirsiniz

renk yapılandırma dosyasının sözdizimi GRASS r.colors yardımcı programı tarafından desteklenen dosyadan türetilir . ESRI HDR renk tablosu dosyaları (.clr) da bu sözdizimiyle eşleşir. Alfa bileşeni ve ayırıcı olarak sekme ve virgül desteği GDAL'a özgü uzantılardır
