A step towards harmonization of Soil Information in Europe

“Web Portal to European Soil Database”

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

ProjectsDevelopment of a prototype for the update of European soil data (INSPIRE)

*Mailing list: In order to keep interested persons up to date.

Soils Portal: Http://eusoils.jrc.it

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 co-ordinate

system• LAEA_ERTS INSPIRE Reference

Grid:Lambert Azimuthal Equal Area

Initial point for the development of a prototype system for updating data

Data (1): Raster Archive

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

5


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)

Documents(1): Research Reports - Papers

6


Collection of maps representing all attributes:

• Soil Database Attributes• Pedotransfer Database Attributes

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)

Documents(2): Map Archive

Example map : volume of stones

7


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)

Applications (1): SOMIS (SOil Map Internet Server) Standalone web-based application for the navigation of soil related maps

8


Applications(1): 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.

Applications(2): Map Viewer Web Mapping Service (WMS) application (OGC compliant)

Runs as a server to serve maps to WMS clients (e.g. INSPIRE Map Viewer) Combine layers of maps located in different Map servers all around the World

INSPIRE Map Viewer: integrating maps residing on OGC compliant WMS servers

Applications(2):Map Viewer

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)

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 1st step(methodology): • Regional data providers would

send data in raster format (participatory approach) to JRC

• JRC would then integrate the regional data in updated European rasters.

Is it according to INSPIRE principles? Example: WRB_LV1

Soil reference group code (WRB)

13


Projects(2): Development of Prototype

10k x 10k raster derived from the Italian Eco-pedological map (scale 1:250.000)

Data are more accurate and detailed

The 1k x 1k raster Grid is even more accurate

Example: RIF_S1 Soil reference group code(WRB)?

14


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?
