  1. IGN Spain Information Systems Coastal and Maritime experiences Ministry of Public Works INSTITUTO GEOGRÁFICO NACIONAL (IGN Spain) Observation of Territory General Department

  2. Summary • Instituto Geográfico Nacional (IGN) • Shared & Distributed Production • National Plan for Territory Observation (PNOT) • PNT • PNOA • SIOSE

  3. IGN (Ministry of Public Works) • IGN (National Geographic Institute) National institution responsible of Astronomy, Geodesy, Geophysics, Spatial Data Infrastructure, Earth Observation, Cartographic Production and dissemination, etc. • Inside our geographic system there is information of coastal and maritime scopes. • Our users are rest of Ministries and National Organizations, Regional Governments, Enterprises, and general public. • “Easy” objective: To satisfy users’ needs with our products, in time, quality and cost.

  4. IGN (Ministry of Public Works) During some years, the geographic information was obtained from diverse ways • Different data sources, institutions, methodologies, time, etc. As a result • Information had not concordance, repeated information, high costs, more effort/time. • No coordination between systems and different institutions • IGN thought up to integrate information systems • Shared and distributed production • INSPIRE principlesof coordination, interoperability, data compilation only one time, costs reduction, etc.

  5. Shared and Distributed Production • Shared and Distributed production • All institution partners participate in • Definition of requirements (for images), requirements & data model (for vector systems) • Costs • Effort (works, tasks, employees) • Benefits • And their level of implication/dedication is established by their competence territory (surface) and their interest • National organizations will pay more than Regional organizations, and big regions will pay more than small regions. • Example: National Plan of Territory Observation (PNOT)

  6. National Plan for Territory Observation (PNOT) • National Plan for Territory Observation (PNOT) • Requirements are defined and established for all partners and expert technical groups • IGN acts like coordinator of tasks and products (quality control) REGIONAL GOVERNMENTS MINISTRIES data IGN cost requirements/data model TECHNICAL GROUPS (i.e. universities) ENTERPRISES AND GENERAL PUBLIC

  7. National Plan for Territory Observation (PNOT) • National Plan for Territory Observation (PNOT) Division of project cost depend of surface

  8. National Plan for Territory Observation (PNOT) It can be defined like a coordinated information systems for national territory, and it develops 3 fundamental sub-projects: PNT, PNOA and SIOSE

  9. National Plan for Territory Observation (PNOT) Two fundamental phases can be identified, Capture & Processing where PNT and PNOA are located, and Information Extraction phase where SIOSE is contained

  10. National Plan for Territory Observation (PNOT) • National Plan of Remote Sensing (PNT) • Periodic coverage of national territory. Including coastal/maritime scopes • Image resolutions • High, 2m-10m (1 coverage/year) • Medium, 10m-50m (3 coverage/year) • Low, 50m-1km (15 min – 30 days coverages) • Radiometric spectrum supported by satellites: SPOT4&5, IRS, Eros, Landsat 5&7, NOAA, Modis, etc.

  11. National Plan for Territory Observation (PNOT) • National Plan of Remote Sensing (PNT) SPOT5 image, 2,5m resolution, pseudo natural color SIOSE

  12. National Plan for Territory Observation (PNOT) • National Plan for Aerial Orthophotography (PNOA) • For all national territory • Unique photogrammetry flight (divided in blocks and strips) • Field control, aerotriangulation • Digital Elevation Model and mosaics of orthophotographies • Periodic coverage of national territory, 2 years. Including coastal/maritime scopes

  13. National Plan for Territory Observation (PNOT) • National Plan for Aerial Orthophotography (PNOA) • Image Resolution of Orthophotographies • 50cm and 25cm per all territory, 10cm per big cities and coast • Radiometric spectrum, natural color and infrared • Digital Elevation Model • By photogrammetric correlation, net of 2m • By LiDAR, density points 0,5point/m2. Altimetric accuracy 0,5m • DigitalModel of Terrain and Digital Model of Surface (including bridges, viaducts, dams, breakwater, etc.)

  14. National Plan for Territory Observation (PNOT) • National Plan for Aerial Orthophotography (PNOA) Some especial studies have been programmed to 2010 • LiDAR bathymetric study for Mediterranean coast • A LiDAR coverage along 450km of coast (from Ebro delta to Nao cape) • Width of 1km beyond sea, and 100m beyond terrain • 25m of depth analysis

  15. National Plan for Territory Observation (PNOT) • Image comparison and detection of buildings study for Mediterranean coast • Using current orthophotographies of 10cm resolution, and old aerial photographies, scanned and rectified • Objective: Detect constructions that were built after Spanish Coastal Law (Ley 22/1988, de 28 de julio, de costas). And help to return the Maritime-Terrestrial public domain, lands of state property. 1956 2002 1956 2007

  16. National Plan for Territory Observation (PNOT) • Land Cover/Use Information System of Spain (SIOSE) • Continuous and homogeneous data base of Land Cover and Land Use for all national territory (vector geographical information system) at scale 1:25.000, minimum size of polygon 2 Ha-0,5 Ha (depend of class) • Made by: • Integration of previous national and regional information system (forestry, agriculture, cadastre, etc.) • Photointerpretation over PNT and PNOA images • Definition an object oriented data model reached by consensus, it makes possible multiple assignation between polygon-class (1:N), using percentages of simple classes Polygon of: 70% Port (under construction) 80% Non-built soil 20% Others constructions 30% Sea and Ocean

  17. National Plan for Territory Observation (PNOT) • SIOSE Products • Data base where also are contained Coastal and maritime classes • Wetlands and waters • Field control photos, around 65.000 per all territory, from them, more than 1.000 along coastal scopes (each 10km)

  18. National Plan for Territory Observation (PNOT) • IBERPIX web site Official web map service of PNOT, where PNT, PNOA, SIOSE images are charged, together with more IGN information, such as CORINE Land Cover or cartography at scale from 1:1M to 1:25k. www.ign.es/iberpix/visoriberpix/visorign.html
