Points Of Interest

pi

A Point of Interest (POI), also called "Service," is a point representation of an activity at a specific location. "Service" represents the activity and not necessarily the building in which the activity takes place. Although the point also may serve as a destination landmark, the point does not necessarily represent an entire physical object.

All specifications, related files and other details concerning all available POIs are found in the MultiNet Points of Interest Specifications. That document contains the core POIs found in standard MultiNet as well as additional POIs only found in the MultiNet POI enhancement product.

The core list of POIs delivered with the standard MultiNet product is found in the MultiNet Data Specification.

Extended Attributes Table for Composite Attributes

pias, piav

The pias and piav tables are used to identify feature components, attributes (*as) and attribute values (*av) that compose certain MultiNet composite attributes. The as and av file identifiers are added to the table of the feature that contains the composite attribute (e.g., pias, piav, a0as, a1av).

Service POI Belonging to Service POI

pr

POI-to-POI Relationships are called "Service Belonging to Service" Relationships. The only Relationships available involving Services are ones where both partners are available in standard MultiNet.

Example: The Service Belonging To Service Relationship is available for Airports and Airline Accesses (Access Gateway) since both Services are available in the standard MultiNet product.

Each POI has its own geometry and basic Attributes stored in the pi Geometry Table. The pr.dbf Attribute table includes the Relationship between a POI and its Entry Point. Even if a POI coincides with its Entry Point, these are still two different Elements in the pi table, and both are related through the pr.dbf Attribute table.

Vicinity Relation

vr

A Vicinity Relation is captured when a POI is located in one Administrative Area but functionally belongs to another Administrative Area. For example, Brussels National Airport in Belgium, located in the municipality Zaventem, functionally belongs to the capital Brussels.

Service in Named Area

sa

The Service in Named Area file identifies POIs that lie within a designated area. These include Administrative Places, Administrative Areas and Index Areas. Relations towards the Index Areas and Administrative Places are built based on MultiNet^® relationship 1014 for all Services, Centers of Settlement and Entry Points.
