Bosnia Herzegovina: Geological Resources Digitization of Hardcopy - PowerPoint PPT Presentation

Bosnia Herzegovina: Geological Resources Digitization of Hardcopy Maps and Data Catalogue 27.07.2011 Simon Neal Dr. Emlyn Hagen 1 CLASSIFIED 30/08/2013

Goal • Gather available data for exploration in BiH • Convert hardcopy data in digital data • Integrate digital data in database for practical use for Shell 2 CLASSIFIED 30/08/2013

Mapping Integration – Example Geological Map Each component provides data that needs to be integrated into a digital geo ‐ database, a few examples are shown below Process RAW input Data Data into Geo ‐ Database Integrated Digital Map (links to well data and 3D model) Features and schema are populated with the Geo ‐ reference scanned map 10 ‐ 12 control raw data from the map and brought together All data is accessible through ArcGIS and points (xy co ‐ ordinates) into a single related spatial database Shell global servers. A few mouse clicks gives access to all data in the system: Digitise map Metadata – Map Name, Date, Type etc features Features – Lithology, Age, Depositional Environment, Description Symbolog y – Feature colour /patterns can represent any data associated with it Extract Data – Area, Percentages, Statistics + Export – e.g to 3D Modelling Package Maps – Create any map you wish with any data Define schema and symbology for = Lithology data + Define schema and symbology for Stratigraphy data 3 CLASSIFIED 30/08/2013

Integration Workflow ‐ Overview Raw Data Collect from various sources Dig. & Ref. Shell CDS / EDM Modernise data and apply format Archive & EP Catalogue Petrel Arc GIS Gravitas Basic data load and archive Create technical insight and data workability Visual wells 3D modelling and interpretation Mapping / Spatial Database database 4 CLASSIFIED 30/08/2013

Raw Data Shell CDS / EDM Digitisation Referencing Described in following slides Archive & EP Process Catalogue Arc GIS Petrel Gravitas Integration Process Not described in these slides Integration step would begin to relate all the data and organise for easy summary and interpretation. 5 CLASSIFIED 30/08/2013

Mapping Integration – Example Geological Map Scan original paper map and split into component parts Surface features to generate digital schema and symbology Lithology to generate digital schema and symbology Lithology columns and Stratigraphy data, generate schema and digitize for model integration Extract map for Geo ‐ Referencing and digitizing Extract cross section for Geo ‐ referencing and digitizing – input to 2D and 3D mapping software Map information for metadata and further symbology – link to Shell Standard Legend 6 CLASSIFIED 30/08/2013
