Reference documents

Main reference documentsExisting data

• At national level– Topographical view– Cadastral view

• At local level– Lack of overview– Existence of 3D data

Detailed information about existing data available

Main reference documentsStandards

• Eurostat classfication of buildings and constructions• LADM (Land Administration Domain Model)• Strong influence of City GML (mainly for the modelling of 3D

data)– Building model at different levels of detail

Extension of scope

• INSPIRE Directive: geographical location of buildings

• Use cases => need for constructions, not only building

• TWG BU description:

“Considered as under scope of the theme Buildings are covered constructions above and/or underground which are intended or used for the shelter of humans, animals, things, the production of economic goods or the delivery of services and that refer to any structure permanently constructed or erected on its site.”

Core 2D profile

1) Scope of theme has been extended: inclusion of constructions (elevated construction, bridges, …)

2) Common attributes OtherConstruction and AbstractBuilding under feature type AbstractConstruction

• 3) Only 3 instantiable feature types

- Building

- BuildingPart

- OtherConstruction

Core 2D profile

• BuildingPart

BuildingPart

This building may be considered as

aggregation of 3 BuildingParts

2D Extended profile

• 1) Link to cadastral parcels and to addresses

• 2) Additional attributes

– About building architecture

– About building management (cadastral data)

• 3) New feature type: BuildingUnit , subdivision of building regarding management aspects

Based on LoD 1 of City GML (the simplest one)

3D Extended profile

• Based on:– Levels of detail 1, 2 and 3 of building model in City GML (descriptions + or – detailed of

building exterior)– Possibility to attach textures (simplification of City GML appearance profile)

• 3D Extended profile is a reservoir of possible extensions for 3D data
