Aerial Surveying in Northern Rhodesia

Extract

One of the most recent and important branches of aeronautics is aerial survey. During the last seven or eight years great improvements have taken place which have developed it into a science of its own. Several aerial survey companies are now operating in various parts of the world, and the untiring and persistent manner in which these pioneers have succeeded in overcoming difficulties has been crowned with success, as it is now accepted by most governing powers as a useful, economical and quick method of surveying.
