SETTLEMENTS PRODUCTION SYSTEM Production system GRDv1 DB SETT Official sources Content updating Resolution Metodology Production Fundamental(core): urban areas Complete urban, rural and others areas for live and work 1 year for the core: automatic 3 years complete (new version): automatic + manual review <= 1 metre Automation of production > 70%, automatic change detection, manual review Coordinate updating at national and regional levels Bottom up approach 40
SETTLEMENTS PRODUCTION SYSTEM Lines of work: Complete the rest of the territory through agreements with the regional agencies Stablish harmonized work flows between national and regional organizations to automate the production (statistical units, geograhical names, parcels and buildings) Bottom up approach. Coordinate a joint and single production of settlements with all regional agencies: technical specifications and production cycles Maintenance: o o Develop automatic processes to link cadastrial data Develop automatic change detectors based on Lidar, images, to reduce cost and time of production 41
Conclussions IGN_ES is promoting and coordinating the production of this fundamental data set at national and regional level Achieve automation > 70% Homogeneous and objective nationwide Metodology based on cadastrial data provides the concept of real state and official boundaries of the territory We delay in the availability of data this year to early 2017 mainly due to the current economic and politic situation and its impact significantly on the ability to involve resources in the project 42
