I have a collection of coordinates which comes from a QGSGeometry object. The shape is a polygon.
qgsGeometry [[(75.2172,17.6566), (75.8499,17.9613), (75.5218,17.2113), (75.2172,17.4574), (75.2172,17.5277), (75.2172,17.6566)]]
How can I change the values of a raster file (geotif) only at the raster cells inside of the polygon (red line in screenshot)?
I know how to transform a raster and write or update with gdal it. But I don't know how to change values only at an given area like the inside of a polygon.
