The SEDRIS Data Representation Model
APPENDIX A - Classes Perimeter Related Feature Topology |
|---|
An instance of this DRM class is a <Feature Topology Hierarchy> instance that spatially organizes its components into a collection of (potentially) irregularly shaped regions, each defined by a <Perimeter Data> link object.
The geographic extent of a thematic coverage might be divided into a collection of tiles. Due to political boundaries or shorelines, some of these tiles might have irregular shapes. The <Feature Topology> instances contained within each tile are organized into components of a <Perimeter Related Feature Topology> instance.
No. The regions defined by the components of a <Perimeter Related Feature Topology> instance should fully partition the topological surface.
No. The organization of <Feature Topology> instances is strict, such that each <Feature Topology> instance shall be located within the region defined by a single component.
| SE_Feature_Topology_Level | feature_topology_level; | 1 |
|---|
The feature_topology_level field specifies the level of feature topology that is present within the hierarchy represented by the <Feature Topology Hierarchy> instance.
