[gdal-dev] Creating DTM Pyramids with max values, and dtm pyramid with min values

[lars.schylberg at blixtmail.se]

Hi,

gdalwarp has an option -r that allows min and max and -tr for output resolution. But the problem remains how to assemble the results in a pyramid the way gdaladdo does.

Hi
I have a DEM , DTM , file.
I need to create pyramid layers, where the values choses are not the average, but the max value from the resampled area. 
and the same using min value from the resampled area. 
There is the gdaladdo application. 
I could not find a mode. 
Is there some way to do this? 
documentation has these modes 
	-r {nearest,average,gauss,cubic,cubicspline,lanczos,average_magphase,mode} 
Is there a way to use them. and how? 
Thanks in advance
