1 GeoCapacity Data, GIS and WebGIS Nichola Smith GIS Specialist British Geological Survey

2 Overview Work package 1 description Data types Data specification & format Data collection methodology GIS Development WebGIS development

3 Work package 1 Inventories and GIS BGS led 2 subsections WP1.1 - CO 2 Source & Sink Inventories Identification of CO 2 point source data Identification of CO 2 sink & infrastructure data Collation of all data into fixed standard format WP1.2 Project GIS Data specification & format Source Sink GIS Web GIS

4 Data Types Point data CO 2 emission sources CO 2 storage site data Natural CO 2 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

5 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 (CO 2 sources) and TNO (CO 2 sinks)

6 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

7 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

8 CO 2 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

9 Data Collection Methodology - Point Data Existing Data Uploaded BGS Merge Sent to partner BGS work with partners to finalise data Partner Add, amend, remove GIS & webgis Final Maps DSS

10 Data Collection methodology - lines and polygons BGS Partner Sent to BGS Data & format check Merge BGS work with partners to finalise data GIS & webgis Final Maps DSS (Pipelines only)

11 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

12 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

13 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 degree Gauss Kruger 117E projection

14 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

15 CO 2 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

16 CO 2 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 Mt

17 CO 2 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

18 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

19 Copyright Copyright interface must accept copyright of the data or GIS will close

20 GIS interface Toolbars European data frame Chinese data frame Table of contents Map View

21 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

22 Customised tools 2 customised tools View copyright data View attribute definition documentation

23 Analysing the data Access to the full data from the GIS Query data based on user specified criteria i.e. select aquifers within 200km of Drax power station where capacity > 600Mt

24 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

25 Thematic maps Can generate user defined thematic maps

26 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

27 Front page and Copyright User must input user ID and password User must then agree to the data copyright before webgis opens

29 Conclusion Excellent collaboration between partners over a large geographical area Produced detailed databases of CO 2 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 CO 2 storage atlas
