Image processing - magnetometry

[Mr PM van Leusen]

HI,

I have a file of magenetometer data taken at 1 m res (ew) and .25 m res (ns)
for a 14 ha area of the Roman town of Wroxeter (UK). It shows quite a lot
of detail but the image also contains a) spikes caused by metal objects in
the soil, b) some horizontal striping caused by the measurement technique, 
and c) 'shading' effect caused by the angle of polar magnetics (about 53
degrees).
Has anyone ver dealt with such data in Grass before and would they be 
willing to share their experience with me?
