3 Soils Portal: Data The European Soil Data Base v2 Raster Archive European Soil Database Documents European Soil Bureau Research Reports-Other Research Reports &Papers European Soil Data Base Map Archive Applications SOMIS (SOil Map Internet Server): Standalone web-based application Map Viewer: Web Mapping Service (WMS) application (OGC compliant) European Soils by theme Soil Erosion Projects Development of a prototype for the update of European soil data (INSPIRE) Mailing list set up in order to keep interested persons up to date with the latest contents on this site. If interested to receive this information, send an to marc.van-liedekerke@jrc.it with subject "Inform me about EUSOILS".

4 Data (1): Raster Archive 10k x 10k rasters derived from the 1:1,000,000 ESDB data Free public access to these degraded but usable data (models) Raster data files for 73 attributes: Soil Database Attributes Pedotransfer Database Attributes In 2 co-ordinate systems: GISCO Lambert Azimuth coordinate system LAEA_ERTS89 INSPIRE Reference Grid:Lambert Azimuthal Equal Area Initial point for the development of a prototype system for updating data

5 Data (2):Distribution of Soil Database Soil Database (distribution version 1) will be available on CD-ROM through the OPOCE (by the end of 2004) Distribution consists of 4 components Soil Geographical Database of Europe Pedotransfer Rules database Soil Profile Analytical database Database of Hydraulic properties Distribution version 2 is under construction Full Database documentation will be available in the Soil Portal: Metadata Database Dictionaries Attributes coding Only the Raw data will not be distributed

6 Documents(1): Research Reports - Papers A repository for European Soil Bureau Network Research Reports (15 reports) A common place for other research reports and papers (11 reports) Multilingual versions of Reports (Example: Manual of Procedures Version 1.1)

7 Documents(2): Map Archive Collection of maps representing all attributes: Soil Database Attributes Pedotransfer Database Attributes Example map : volume of stones PDF format (A3), sizes typically between 1 and 2 MB Dominant value Maps For each theme, 3 maps available: Thematic Purity: is an indicator of the quality of a thematic map Confident:an indicator of the quality of an attribute value (provided by the contributor)

8 Applications: SOMIS (SOil Map Internet Server) Standalone web-based application for the navigation of soil related maps Simple Map operations: Zooming, panning, querying, layering User can view and inspect soil data but cannot download User friendly application No need for specific S/W(only web browser) Fully documented (Contents of European Soil Database CD-ROM) 2 Map applications : multiple soil related layers (Grouped in 3 categories) single WRB soil layer Built with free web mapping software Open Source (Minnesota MapServer)

9 Web service and SOMIS (Soil Map Internet Server)

10 European Soils by theme: Soil Erosion Place to make available information about Soil themes CD-ROM: Nature & Extent of Soil Erosion in Europe (PESERA project) Pan European Soil Erosion estimates (t/ha/yr) data (from PESERA project)

11 Applications: Future developments - What is next? Full development of all the layers (73) derived from Soil Geographical database Development with ESRI ARCIMS software more efficient development and delivery of web mapping application more functions in the off-the-shelf user interface In context of INSPIRE development of two additional map services : one for ITALY 1:250,000 or 10km x 10km GRID one for a Regional project (maybe Alpine Project) in a smaller scale (1km x 1km GRID) investigate how these developments can be further adapted to INSPIRE principles.

12 Accessing, exchanging and delivering spatial data INSPIRE PRINCIPLES Spatial data should be stored, made available and maintained at the most appropriate level (avoid duplicates). It must be possible to combine spatial data from different sources across the EU seamlessly and share them between several users and applications. It must be possible for spatial data collected at one level of public authority to be shared between all levels of public authorities. Spatial data needed for good governance should be available under conditions that do not restrict their extensive use. It should be easy to discover available spatial data, evaluate their fitness for purpose and know the conditions applicable to their use. HOW WE IMPLEMENT THEM Central EU Access: for Pan- European data relevant for European Policies (framework directives) Common WRB classification, common projection system (LAEA/ETRS89), harmonization of SMU limits with agreed base map (EuroGeographics) Bottom-up approach and GRID approach to allow national/regional/local levels to update higher levels by generalization Access to environmental data of interest to citizen (Public Sector Information Directive) through easy download respecting ownership and property rights Metadata about data (ISO 19115) Query tools as the ones available in EU GEO Portal

13 How to enforce those basic principles at EU, National, Regional and local levels? A project of directive (initiated by ESTAT, ENV and JRC/IES/LMU) aiming at creating a legal framework for the establishment and operation of an infrastructure for Spatial Information in Europe, for the purpose of formulating, implementing, monitoring and evaluating Community policies at all levels and providing public information Practical implementation by Member States supported by the use of technical guidelines or cookbooks prepared by the user community and JRC (based on common industry standards and international organisms such as ISO or CEN). Reprojection of European Soil Database in decimal degrees (ETRS89) and LAEA for analysis and display Example of raster archive snapped on the Reference GRID Generation of ISO compliant metadata WEB Mapping applications for accessing data (while respecting ownership) EU SOIL Portal is the contribution of the S&W Unit to the building of a thematic spatial data infrastructure on soils

14 LAEA/ETRS89 Projection System Projection system: Lambert_Azimuthal_Equal_ Area False_Easting: False_Northing: Central_Meridian: 10 E Latitude_Of_Origin: 52 N Geographic Coordinate System : ETRS_1989 Prime Meridian: 0 Mapping Projections for Europe, Workshop, Marne-la-Vallée, December

15 LAEA Eurasia Projection: Lambert_Azimuthal_Equal_Area False_Easting: False_Northing: Central_Meridian: 65 E Latitude_Of_Origin: 52 N

16 Common European Reference GRID Development of a common reference GRID for reporting and statistical analysis Growing interest for soil mapping delivered on a pixel basis (modeling, harmonization issues, updating issues) er_archive/ref_grid_sh_proc_draft.pdf

17 Workshop recommendations for a common reference GRID System simple (supported by common GIS tools on the market) System hierarchical (metric structure) Unified European GRID coding system based on the LAEA/ETRS89 coordinate system Clear and simple relation to the coordinate reference systems recommended by the Spatial Reference and the Map Projections workshops in Marne la Vallee European Territory should be partitioned into units of equal area. Based on ISO standards Timestamp GRID Data model documented Format of GRID data outputs based on a non proprietary open format. Metadata are a indispensable component of any future GRID system

18 Examples of 1 km GRID common datasets SRTM Elevation data, Corine Land Cover, Eco-pedological map of Italy

19 Projects(1): Development of Prototype 10k x 10k raster derived from the 1:1,000,000 ESDB data Question:How those grids can be updated? A proposed 1 st step(methodology): Regional data providers would send data in raster format (participatory approach) to JRC JRC will then integrate the regional data in updated European rasters. Is it according to INSPIRE principles? Example: WRB_LV1 Soil reference group code (WRB)

20 Projects(2): Development of Prototype 10k x 10k raster derived from the Italian Eco-pedological map (scale 1: ) Data are more accurate and detailed The 1k x 1k raster Grid is even more accurate Example: RIF_S1 Soil reference group code(wrb)?

21 Projects(3): Questions -Remarks All rasters should be produced according to the nested grid system proposed for the European reference Grid (1k, 10k, 100k ) All rasters should be produced according to the same co-ordinate system (ETRS_LAEA) Use of unique labelling of grid cells The data values provided by the Italian raster should match classes/instructions imposed by the European level If the European raster is at 10k, should the Italian raster sent be 1k or 10k? What should happen at the borders of Italy? Raster cells overlap with cells from neighbouring countries How often the data will be updated?

22 Web services and INSPIRE viewer (accessed through EU Geo Portal) for integrating maps residing on multiple spatial servers

23 ISO metadata COMPLIANT ISO Metadata Benefits: easier access to relevant data through queries Better assessment of data quality Better evaluation of data access constraints ACCESS to Metadata has to be FREE

24 Web service accessed through ArcIMS more efficient development and delivery of web mapping application more functions in the off-the-shelf user interface

25

26 Web services and GIS Access through a GIS application for additional analysis or overlaying with additional layers (Corine, DEM, more detailed reference layers)
