raster to vector (brown layer) - dxf, georeference, import to OCAD, classify line types - trial area of 0.5 sq km
won't go same path with black - mainly point feature rock, or grey (area edges not handled well in raster to vector software, easier to trace from raster background) - green and yellow significantly changed since 1990 so not worth converting to vector.
