How can i do this operation:
I want to get a pixel value fro the satellite image
(Landat, GeoTIFF, 7 bands) using qgis-python.
What operators should i use? (for example in qgis's Python Console)
I do not know whether work for you or not , but you can check out gdallocationinfo. it is a raster query tool from gdal...
i hope it helps you...
there is another way:
this code show the value pixel for all 3 bands composit in image. Band 1 pixel value = 104; Band 2 pixel value = 119; Band 3 pixel value = 54;
