I am doing my masters in archaeology, but have used GIS for some time now, however this is my first attempt at generating and using rasters. I appear to have been successful for some, but not so well for others. All the books and tutorials I have looked at don't really explain what the different values are when creating a raster and I'm unsure if I should be changing the default values to something else to produce the image I want and if I am to change them what to? I could spend a life time changing the values, but still wouldn't be sure I understood what they did.
Can anyone recommend a book, blog, tutorial that would help me with this?
I am using GRASS, QGIS and ArcMap/Scene, but if there is another program out there that could be useful I'm willing to try.
