Ah grasshopper ! A couple of hours is merely the blink of an eye on the cosmic timescale of the average open source programming task... You need to provide more information so that people here can help you. On the input side: are your contour lines either LineString objects are something that can be turned into LineStrings ? On the output side: were you wanting proper interpolation of values between contours for the output raster or would simple filling the regions between contours with a uniform value be ok ? For true interpolation you would usually use an algorithm such as Kriging which GeoTools does not provide. Also, take a look at this message in the list archives... http://osgeo-org.1803224.n2.nabble.com/How-can-I-convert-mid-mif-map-to-matrix-of-big-cells-with-average-territory-information-tp1943037p1943037.html While it is not exactly the same use case that you have it might give you some ideas or help you get started.
