Data Preparation
Data Reduction & Simplification
Tagging Plans
On each created changeset there are 2 tags :
- source: 510/IGN
- comment: Automatic import of roof shape and roof material in St. Maarten.
Changeset Tags
One changeset will be created for the total import.
Data Transformation
The only data transformations are to add a new roof:shape tag and a roof:material tag to the buildings. When a corresponding tag already exists, the addition will be skipped.
