Can't you just export the reflectance raster to an "x,y,z" file?
Using gdal_translate, choose the output format "-of XYZ". You can do
this in QGIS, or using GRASS you can also export to a .csv file.

Hi,
I am working with an agricultural research team analyzing
multispectral imagery taken from a UAV over fields
containing plots with different nitrogen treatments. I created
a grid over my geotiff in QGIS, and have run zonal statistics
on this layer and compared the output from this to actual leaf
analysis to derive a correlation. That is looking nice.
What I wish to do now, however, is to obtain each
individual reflectance value for each pixel in my grid
plots. So, for example, zonal statistics tells me there are
22348 pixels in a plot and it tells me the max, min, median
etc. I would like to see the values for each of the 22348
pixels and work with that. It will be a monstrous file I know
but I can live with that.
Is there a plugin that will quickly export this info for me
to .csv or txt?
Cheers
