Overview

• Work package 1 – description

• Data types

• Data specification & format

• Data collection methodology

• GIS Development

• WebGIS development


Work package 1 –

Inventories and GIS

• BGS led 2 subsections

WP1.1 - CO2 Source & Sink Inventories

Identification of CO2 point source data

Identification of CO2 sink & infrastructure data

Collation of all data into fixed standard format

WP1.2 – Project GIS

Data specification & format

Source Sink GIS

Web GIS


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

User guide supplied

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

Xian 1980 3 degree Gauss Kruger 117E

projection


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


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


CO2 Storage locations

• Database contains information for potential storage

within

Aquifers

• 991 sites across 24 countries

Hydrocarbon fields


Coal fields


• Total potential storage capacity of ≈ 360000Mt


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


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


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


Customised tools

• 2 customised tools

View copyright data

View attribute definition documentation


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


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


Thematic maps

• Can generate user defined thematic maps


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


Front page and Copyright

• User must input user

ID and password

• User must then agree

to the data copyright

before webGIS opens

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

atlas
