Automating Spatial Data Sharing
2 likes439 views
This document discusses automating spatial data sharing between data producers and end users in Wallonia, Belgium. It describes using FME to create an integrated workflow that simplifies data sharing. The workflow validates and transforms data from multiple producers into various formats, then distributes updated data on demand to end users based on their specifications. This automated process saves time by eliminating repetitive manual data distribution tasks.

- 3. The context & needs
- 4. Sharing public spatial data ● Direction de l’Intégration des Géodonnées ○ Directorate-General of the Walloon Public Service (SPW) ○ Interface with Departments regarding geographical information ○ Geodata sharing and exchange infrastructure ● InfraSIG: Walloon-SDI (Walloon Geomatic Decree - 22 Dec. 2010) ○ Geoportal of Wallonia ○ “Plan Opérationnel Géomatique pour la Wallonie” (POGW) ○ INSPIRE coordination & Implementation ● Open geo-data promoter
- 6. Simplify data producers contribution ● Share multiple datasets (readers) ● Update shared datasets frequently (> 29 millions spatial objects for PICC) 280+ datasets
- 7. Simplify data producers contribution ● Share multiple datasets ● Update shared datasets frequently ● Offer flexibility - added-value ○ Validate (quality, schema conformity...) ○ Restructure - Transform (producer model => sharing model
- 8. Simplify data producers contribution ● Share multiple datasets ● Update shared datasets frequently ● Offer flexibility - added-value ○ Validate (quality, schema conformity...) ○ Restructure - Transform (producer model => sharing model) ● Save time and simplify multipurpose data processing => integrated workflow PICC PICC-vDIFF PICC-vTOPO
- 9. Simplify data reuse by end-users ● User’ specifications ○ “As-is” to specific models ○ Area of interest (local to regional) ○ Coordinate system – harmonised transformation
- 10. Simplify data reuse by end-users ● User’ specifications ○ “As-is” to specific models ○ Area of interest (local to regional) ○ Coordinate system – harmonised transformation ○ Usable format => Extraction & Conversion capabilities GIS CAD RASTER 3D INSPIRE
- 11. Simplify data distribution ● Eliminate repetitive (semi-)manual data distribution tasks ● Producer & User requests have to be automatically processed ● The platform analyze, restructure and publish updated data ● The platform crops the data for delivery by download with ○ Priority processing considerations ○ e-mail notification ○ Harmonised zip file structure (data + metadata) => ETLSPAT Platform
