Cartography and Spatial Data

The Cartography Datasets are an integral component of the comprehensive Exploration and Production Database. This geographic module provides the foundation for hundreds of high quality maps for the petroleum industry as well as the background features of IHS data browsers and GIS applications.

All datasets contain coordinate values for features within the international database which are entered as reported together with geodetic parameters. Furthermore, we manage a comprehensive portfolio of datum shifts to facilitate the computation of our Global WGS84 feature layers.

Surveys
Cartography Database

The Cartography Database 1M (1 million scale) consists of a worldwide set of layers in vector format (lines, points or polygons) at a nominal scale of 1 million including the following features available with major attribute fields

  • Geography Layers (Coastlines and Islands, Rivers and lakes, Cities, Onshore borders, Wetlands, Countries)
  • Bathymetry layer containing water depth contours
  • Province layers including administrative subdivision lines and polygons at various levels
  • Licensing grid
  • Offshore Boundaries and Limits layer containing ratified borders, major claims and some national limits such as 200 nautical miles

The Cartography Database at 150 million scales provides a worldwide set of layers including the following features

  • Onshore Countries: Polygons representing worldwide country areas
  • Offshore Countries: Polygons of offshore territorial claims
  • Geographical terrain: Onshore, shelf and deepwater subdivisions

Updates and Additions 2017

There have been multiple additions and updates to all areas of the cartography database for many Regions and Countries during the first half of 2017. View a detailed breakdown of the content added and updated.

Key Highlights - 2017 (June)

During 2017 we have continued to work on our geodetic review of well spatial data, focusing on Thailand and Malaysia during the first half of 2017 which has resulted in:

  • Malaysia and Thailand - 99% have defined geodetic information which has been through a rigorous QC process and validated
  • Approx. 10,000 wells in Thailand, 1,000 wells in Brunei and 1,700 wells in Malaysia had geodetic information updated

We have now moved our focus to Africa and are looking first at Egypt, Angola and Algeria where we hope to improve associated geodetic information by 30% within these countries.

Other geodetic projects completed include:

  • Algeria - 1,416 wells validated using imagery and flag assigned and 430 datum updated from Unavailable to Nord Sahara 1959
  • Argentina - 48,782 wells validated using imagery and flag assigned
  • Qatar: 1,094 wells updated including 565 wells from UNV to reliable datum. Now all Qatar wells have reliable/assumed datum
  • Indonesia (Kalimantan): Geodetic datum updated in 9,245 wells
  • Angola: 572 wells validated by satellite imagery and 244 have been assigned to Camacupa datum

Key Highlights 2016

During 2016 a full geodetic review of well spatial data in Latin America countries was completed resulting in:

  • Overall 96% Latin America wells have a defined geodetic information
  • More than 99% wells in Brazil (29,323 wells ), Chile (3,746 wells) and Mexico (32,051 wells) have geodetic information recorded

As a global project, we aim to provide around 90% of wells globally with associated geodetic information. We have now moved to Indonesia where 26,000 wells have had an improved datum assigned.

Project Overview

To enable clients to view our data with Google Earth and Bing Maps, alternative layers have been created based upon the WGS84 datum. This presents several challenges as typically, data is gathered from a variety of sources, most often without a geodetic identifier and transformation parameters from Local Datum to WGS84 may not be known.

Where there is no available coordinate system an 'area standard' transformation is performed using an assumed datum. This is not always transparent and opens the possibility of inconsistencies between the local and WGS84 layers. Details of all assumed datum are available in our Datum Shift reports below.

We are undertaking a substantial Geodetic Review of all spatial datasets to produce the best possible WGS84 layers. Typically, includes:

  • Research into coordinate systems
  • Sensibility checks on geodetic attributes
  • Assign assumed geodetic attributes where required
  • Research into transformation parameters to WGS84
  • Quality assure transformation parameters
  • Updated geodetic qualifiers as necessary
