如何使用GDAL将色表添加到一个波段的Tiff中？

我有1个波段的GeoTIFF文件。带的颜色解释为灰色。我想要一个颜色表，以将其转换Col.tiff为Col.jpeg或Col.png。

我尝试通过.vrt在此tiff中放置一个颜色表：

gdal_translate -of VRT  Col.tiff Col.vrt

然后添加.vrt：

<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>

并再次翻译：

gdal_translate Col.vrt Col.tiff

但它回答：

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.

我该怎么做？

有关信息，请参见乐队的gdalinfo：

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

使用gdal，您可以基于gdal_dem（color_relief）为图像着色

颜色配置文件的语法派生自GRASS r.colors实用程序支持的语法。ESRI HDR颜色表文件（.clr）也与该语法匹配。alpha组件以及制表符和逗号作为分隔符的支持是GDAL特定的扩展
