[Qgis-user] Raster statistics manipulation

[Matt Boyd]

Hi QGISers,
I've got a raster / grid that's been normalised to values between 0 and 1.
What I need to do is use this grid to create another grid that uses the
normalised grid as an influence. I've done this before using krigin but
can;'t quite work out how to get there.

Inputs: Grid 0-1 values, distribution is close to normal with a median
value of around 0.25.

I want to create a grid with a similar distributiuon, standard deviation
etc but that has a median value around 0.5

Any tips?

Thanks
Matt
