Eric posted on his site about access to the new Series2 HGT radar maps for use with Ground Control. No doubt they are far superior to Series1. At least for South Australia, I found the setting for sea level of the infinite plain to be most accurate when Z set at 0.0025 (still reads as 00!) I am hoping that Eric, or someone, will explain usage of the other new downloads which, apparently, will more accurately set sea levels but, also, the water levels of lakes etc that are above sea level! I wonder what it will do for the many dry salt lakes we have in South Australia which are below sea level?
