Wish ScurvyDDog was still posting. Would be very interested to hear what the people behind the screens have to say. The argument is if the technology is capable to supply the correct information, what the tinpushers are made to do with the technology wrt sector sizes, and now how accurate the terrain data is...which is a bloody joke for an argument because we have had DEM data down to 5m grids freely available from GeoScience Australia since 2011. This all smells of politics and arse covering.
