Introduction
… So far, How has IGN Spain worked to provide INSPIRE compliant TN data?
• Identifying the IGN datasets containing the most representative TN data
• Mapping those datasets data model with INSPIRE data model
• Any national dataset isolated is not as complete as TN INSPIRE data model
• Some national datasets contains more information than the features considered by
INSPIRE
• Providing only the mapped data according to INSPIRE schema via:
• Download services WFS
• Visualizing services WMS, WMTS

Introduction
In order to to provide a seamless INSPIRE compliant TN dataset in March 2014, IGN Spain defined a new production strategy focused on:
∗ Generation of the Geographic Reference Information TN DB: ∗ INSPIRE compliant ∗ Considering the TN national datasets requirements
∗ Any TN data in these products shall be derived from the TN BD
∗ It should be as much accurate and updated as possible

Geographic Reference Information on Transport Network (IGNE TN):
Data model definition
INSPIRE Conference 2017

1st PHASE: Analysis of the lGN datasets data models: ∗ Main products with TN data: CartoCiudad (streetmap), DB 25,000 & 100,000) ∗ Exchange Data Model between IGN & Regional Mapping Agencies ∗ Other TN models (Ministeries…) ∗ Result: features, attributes and association required in Spain 2ndt PHASE: Analysis of mappings: ∗ Mapping tables between National requirements and INSPIRE
3rd PHASE: Create an INSPIRE compliant application schema
4rd PHASE: To document the new product • ISO19131 compliant specifications: http://www.ign.es/web/ign/portal/cbg-redes-transporte

Data production: How and When?
Geographic Reference Information production planning: 2 STEPS
GRI TN
1st version
1ST STEP: The TN v1 is populated from existing data
2nd STEP: The DTN v2: updating v1 improving accuracy

IGNE_Transport Network: DB v1.0
• WHEN? Production period: 2015-2016 • HOW? Integration of the existing data according to IGNE TN Requirements:
o New features types, attributes and relationships: e.g intermodal connexions
• SCOPE: Challenge: to produce TN data for the whole Spain • WHAT? TN Data: 25,000 in rural areas & 1,000/2,000 in cities Near 1 m acuracy in cities, 3 m in rural areas
Jun 2017: data available via Web Services

IGNE Transport Network: DB Loading Status of data production:
• Finished the whole production (March 2017) Data loaded in PostGis: all Spain

IGNE TN v1 available
• Next steps:
• To finish INSPIRE WEB Services implementation: ATOM
• To update the GRI TN to v2
• To update data and improve its accuracy: • 2017-2019: urban roads will be updated all over Spain • From 2019 roads geometry accuracy will be improved
• rms < 1m; continuous updating, 1 version each 2 years • By Mobile Mapping technology

Conclusions
∗ To be INSPIRE compliant does not imply new production data ∗ But it should be considered as a trigger to rethink the
traditional production methodologies : ∗ To be more efficient -> do not duplicate data capture -> reuse data ∗ To provide the data and services that users required
currently: continuous, accurate and updated TN data
