[GRASS-user] Problem- " Flood zone analysis", "de-correlation stretching", "Bitmap" in windows

[SWAPAN GHOSH]

Dear All,

How I can solve the problem like-

1. Flood Zone Analysis( Hydrographical properties of an Flood Zone, given
the DEM parameters).
2. De-correlation stretching.
3  Bitmap( Given raster map, set non nul value for the user specified area(
given small sample vector or small sample raster)).


Thanks & Regards,

Swapan Ghosh
