Data Types
• Point data
CO2 emission sources
CO2 storage site data
Natural CO2 emission sources
• Line data
Pipelines
• Polygon data
extents of aquifers, hydrocarbon fields and coal fields
• Baseline data
coastline, urban areas, rivers, roads
• Raster data (georeferenced images)
• MS Word documents

Data Specification
• Data specification builds on previous projects
GESTCO
CCC_EUR
CASTOR (GESTCO East)
• Developed to meet needs of the GIS and DSS
• Developed in conjunction with EcoFys (CO2
sources) and TNO (CO2 sinks)

Data Specification (cont..)
• Defines
file type (point, line, polygon)
file format (MS Access, ESRI)
attributes names
attribute descriptions
numerical units
• Specifies input constraints
attribute type (numerical / text)
drop down list options
• Default values
• Data projection

Data Collection
• The problem
26 partners based in 20 different countries
Updating data and creating new data
Need to ensure data consistency
Data transfer between partners
• The solution
Each partner provided with specifically designed
database for each point data category
Detailed specifications for line and polygon data
sent to partner

CO2 Source & Sink Databases
• Developed using Microsoft Access
Standard Office Software – most have it
Data Input forms – guide user
Data entry constrained – drop down lists
Can ensure data consistency
Easy to supply to partners

Quality checks
• Check required attributes have been populated
• Check correct units have been used
• Flag any apparent anomalies in the data
• Ensure all point data has location coordinates
• Check attribute names used for line and polygon
data
• Check location of data in the GIS – does it plot
where expected
• Document progress of data and changes that are
made

Copyright of the Data
• The data remains the copyright of the partner who
provided the data
• Copyright statement on the GIS and webGIS
• Users must accept the copyright of the data before
data can be viewed
• Copyright statement details who owns the data
copyright and the contact details for the partner

Data Projection
• European Data
Lambert Conformal Conical Projection of the
WGS 84 ellipsoid
The projection parameters are identical to those
used for the Digital Geological Map of Europe
(IGME project of BGR/Eurogeosurveys)
• Chinese Data

Data Storage
• GIS vector data (points, line and polygons) stored in
ESRI geodatabase format
• Raster images stored separately and linked into the
GIS
• Documentation stored as MS word documents and
linked in to allow concurrent viewing of the data and
any written documentation
© NERC All rights reserved
CO2 Emission sources
• Database contains information on 2217 emission
sources spread across 26 countries
• Includes information on
Location
Plant name
Emissions
Fuel
Capacity
Emission factor
Source of the information
© NERC All rights reserved
CO2 Storage locations
• Database contains information for potential storage
within
Aquifers
• 991 sites across 24 countries
Hydrocarbon fields
• 1388 sites across 19 countries
Coal fields
• 227 sites across 14 countries
• Total potential storage capacity of ≈ 360000Mt
© NERC All rights reserved
CO2 Storage Location Data
• Data contained within the database includes
information such as
Location
Storage capacity
Permeability
Porosity
Pressure
Lithology
Remarks
• Polygon data showing extent of storage location
also obtained
© NERC All rights reserved
GeoCapacity GIS
• Objectives
Incorporate the wide range of data available
Allow meaningful access to the data
Allow simultaneous viewing of one or more
layers and extensive analysis of the data
• Software
ESRI ArcGIS 9.2 Desktop GIS system
Customisation using ESRI ArcObjects and VBA
© NERC All rights reserved
Copyright
• Copyright interface – must accept copyright of the
data or GIS will close

Data within the GIS
• All available vector data loaded into GIS
• Data categories grouped within table of contents
• Appropriate symbology defined – can be changed
by the user
© NERC All rights reserved
Customised tools
• 2 customised tools

Analysing the data
• Access to the full data from the GIS
• Query data based on user
specified criteriai.e. select aquifers within 200km of Drax
power station where capacity > 600Mt
© NERC All rights reserved
Summarising the data
• Create summaries and view statistics of the data
• Gives user an overview of data within the GIS
i.e. summary of the total emissions for each
country in Europe
© NERC All rights reserved
Thematic maps
• Can generate user defined thematic maps
© NERC All rights reserved
GeoCapacity webGIS
• Developed using ESRI’s ArcIMS software
• Allowed partners access to data for checking once
processed at BGS
• WebGIS to be maintained for the coming years
• Accessed via GeoCapacities website
• Partner only secure access
• Does not have full functionality of project GIS
© NERC All rights reserved
Front page and Copyright
• User must input user

Conclusion
• Excellent collaboration between partners over a
large geographical area
• Produced detailed databases of CO2 emissions and
storage sites across Europe and the Hebei province
in China
• Consistent data from each country
• Geocapacity GIS – provides access to the data for
analysis and interrogation
• First step to producing an EU wide CO2 storage
