[Qgis-user] Export reflectance value for every pixel in a zone

[Joshua Rust]

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

Josh
