Accuracy of Heights from Ordnance Survey Maps

1) Spot heights at summits have an accuracy of about ±3.3m at all map scales, in agreement with the published figure. 2) Levelled heights from old 6-inch maps can be a few metres below the summit but are unlikely to be more than a few tenths of a metre higher. 3) The accuracy of old and new 1:50k maps is similar, but where heights have changed the old height has a tendency to be too low. 4) Spo...

Extracting Plans From Plans

Propositional plans of all forms often display a certain level of concurrency which can be exploited by scheduling the plan. This reveals the earliest times at which each action can be applied whilst still achieving the goal and shortening the plan duration. However, the output of this scheduling process is simply a set of timestamped actions, losing implicit information present in the original...
