<p class="MsoNormal">I have individual TIFS from the different sensors on the drone. Currently, I have the R, G, NIR, and Redge bands. Is the correct method to merge these into a multi-band image that I can then view as NDVI or apply other algorithms against
just to use:<br>
<br>
gdal_merge.py -separate R.TIF G.TIF NIR.TIF RE.TIF -o multispec.tif<br>
<br>
I noticed that only the first band is listing as:<br>
Band 1 Block=2580x1 Type=UInt16, ColorInterp=Gray<br>
whereas all the others are listing:<br>
Band 2 Block=2580x1 Type=UInt16, ColorInterp=Undefined<br>
<br>
Any attempts to define them as ColorInterp=Gray through gdal_edit fails to yield any results.<br>
<br>
I was just wanting to confirm I have the correct workflow here. I haven’t had any luck viewing the multispec.tif within QGIS by applying any RasterCalculations on the bands in the multispec.tif, so I was wanting to confirm I’m not doing anything incorrectly.<br>
<br>
I’ve also attempted to pull out the blue band from the RGB camera, and add that to the multispec.tif as well, after scaling it from the 0-255 to the 0-65535, and that displays the blue band in there. I can then ColorInterp bands 1, 2, and 3 as red, green,
and blue, then it appears to let me specify the 4 and 5 bands as gray, but the colors are way off.<br>
<br>
Can anyone offer some assistance?<o:p></o:p></p>
