[gdal-dev] Censor area in tiles of aerial image

[Carsten Lockenkötter]

Hi,



is it possible to censor specific areas of an aerial image using GDAL?



I have several smaller tiles that I've already transformed into my desired
coordinate system and generated internal pyramids.

Subsequently, I would like to censor certain areas based on polygons (e.g.,
from a shapefile or an Oracle DB) (coloring them grayish).

Set the color must be done after transforming coordinatesystem and
generating pyramids.



I usually use the compiled Windows binaries from gisinternals.com.

Presumably, my plan doesn't work with that, right? At least I haven't found
anything in that direction.

I suppose this could be done with a Python, but I've never worked with
Python before.

Do I need to adjust the internal pyramids as well? Or do I have to recreate
them?



Could you please show me a brief example of how it could work, so I have an
approach?

I just need an idea of how to implement this and possibly some tips on what
else I need to consider.



Regards,

Carsten
