[gdal-dev] combine two raster data

[Tsering W. Shawa]

I am looking for a script to combine two raster data that have unique values. For example, one raster has administrative unit name and another has land cover data. I want to combine these two raster data to find a relationship between two data. I can do the same process in another GIS software but wanted to find an option to do this using gdal. 

Any suggestion or help will be appreciated.

Thanks,
