Today's Announcement from KML compares an image of the 200 metre government data with the KML new data.

Can some one please tell me why you would grid 200 metre data using a 250 metre cell size? Surely, standard practice would see a 40 metre cell size used (being 1/5 the line spacing).

Perhaps KML should contact a geophysical consultant if this is the quality of processining they are doing in-house? If would be alot cheaper then flying new surveys.
