UPDATING AND SPECIFICATION CHANGES - STATISTICAL ESTIMATION OF WORKLOAD
Dorthe Holme · 2002
The vector dataset Top10dk is updated incrementally and new features are added as single objects and objects that are no longer valid are made historic. Single objects can be revised by choosing one of two methods depending on what is considered most suitable in the specific situation. This paper will look into the usage of the two methods and conclude how the two methods are applied in the production of revision data for Top10dk. The paper analyzes statistical material based on the last three years production of revisions. Based on these statistics estimates of the extend of future updates are made. Changes within the specification of Top10dk cause a changed workload within the production of revision data. The changed workload is assessed as a correlation between a specification change and the number of revision objects needed to implement the specification change. The experienced gained from the present investigation suggests that a statistical production monitoring system would benefit future workload estimates.
