• 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: In order to keep interested persons up to date.

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 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 (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
4
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)
5
Documents(2): Map Archive
 Collection of maps representing all
Example map : volume of stones
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)

Applications (1): 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)
7
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
user
Regions Map
Soils Map
9
Applications(2):Map Viewer
INSPIRE Map Viewer: integrating maps residing on OGC compliant
WMS servers
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
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)
12
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)?
13
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?
