----------------------------Original message---------------------------- Dear All, Just out of curiosity when you refer to a revised and updated DCW what do you mean? The original DCW was as I understand it simply the ONC 1:1m maps digitised. Many of the ONCs were done in the 1960s with only the aeronautical element kept up to date. If DCW is being revised does this mean, for example, that someone is adding in the South African motorway network, and all the rest of the changes which are currently not there?
