Maps and Other Content

Geofacets contains over 1.5 million maps, figures, and tables sourced from esteemed scientific publishers, including:

  • Elsevier’s market-leading Earth science journal collection
  • Geological Society of London’s Lyell Collection
  • Society for Sedimentary Geology
  • Society of Economic Geologists
  • Geological Society of America
  • Wiley (and American Geophysical Union)
  • Society of Exploration Geophysicists

As the journals included in Geofacets publish new articles, we update Geofacets with new content on an ongoing, monthly basis. Geofacets only contains articles that have maps, figures, and/or tables. Maps are downloadable into GeoTIFF, GeoTIFF + Metadata, KMZ, JPEG, TIFF, and Shapefiles (for select content). Tables are downloadable into XLSX files, and figures are downloadable as TIFF files.

Geofacets also contains multiple overlays, with information sourced from third party providers. Geologic basin overlays are provided by IHS and Robertson. Wood Mackenzie’s map overlays provide high level commercial information for oil and gas exploration, including unconventional gas plays around the world. C&C Reservoir’s map overlays provide global field locations, with links to the FAKS database. The IODP overlay includes locations drilled as part of the International Oil Drilling Project.

While Geofacets includes journals most relevant to the Oil & Gas industry, it also includes content related to other industries such as mining, engineering and environmental sciences (e.g. climatology, geochemistry, volcanology). It is significantly easier to discover relevant maps because Geofacets offers users the ability to filter content by map attributes and find maps by region or keyword versus scanning through text articles. Tables and figures are also discoverable in Geofacets, and can be downloaded as XLSX and TIFF files, respectively.

While all maps from Geofacets are downloadable as TIFF or JPEG files, there are a few possible scenarios for why maps found in Geofacets could not be georeferenced:

  • If a map is hand-drawn with errors introduced, which is common to maps generated prior to the mid-1990s when computers were not regularly used to generate maps
  • If a map's scale cannot be determined or the scale is distorted
  • If our modern day coordinate system does not apply to a map, i.e., for paleogeographic maps which depict geographic locations and movement of continents through geologic time
  • If a map's geographic coordinate system or projection cannot be determined
  • If a map has no geographic coordinates and/or geographic identifiers (e.g., countries, cities, states, etc.) that can be used as a reference point

Geofacets' maps are indexed using IHS's geologic basin classification. IHS is a well-respected global provider of technical information, decision-support tools and resources for the energy industry.

Geofacets can help geoscientists find maps, tables, and figures that aid in identifying geological analogs, thus improving understanding of the subsurface geology of a basin, prospect or reservoir. All maps include a unique metadata index that enables geoscientists to refine search results by map type, surface area, article keyword and journal, allowing users to quickly find specific data needed for analysis and interpretation. Tables, containing rich data about the characteristics  (e.g. sedimentological, geophysical, geochemical) of a geological entity (e.g. source rock, basin, reservoir) can also aid in analog research. Figures, like well logs, can help users understand characteristics of nearby wells.

Also, geoscientists can use a keyword search of the map caption and unique map metadata (e.g., map type, geologic basin)—in addition to typical search of the article title, abstract and author keyword—to uncover information that may have otherwise been overlooked, potentially opening up a whole new line of thinking.

Geofacets customers must comply with all terms of their subscription agreement and the terms and conditions associated with each map, figures, and/or table - including restrictions on republishing the original or modified content. Any public display or republishing must be cleared by the copyright holder, however any internal use is allowed. The terms and conditions for map use vary based on publisher and may be accessed via the Detail Window in the product.

We are always looking for quality and relevant content partners. In addition, we are continually updating our existing content base by adding content weekly as new journal volumes are published.

At this time, the Geofacets content base contains only English language publications.

Maps are georeferenced by trained staff and must pass strict screening criteria to ensure proper geographic information is present before being georeferenced. The map must contain an adequate number of coordinate pairs (marked latitude/longitude intersections) and/or geographic identifiers must exist in at least three map quadrants for a map to be georeferenced. All other maps (about 25%) are geolocated (approximate map location is determined using information from the caption or title).

Georeferenced map alignment accuracy is checked by:

  • Visually comparing the alignment of map control points with a basemap.
  • Assessing the root mean square (RMS) error of the georeferenced control points compared to control point on the basemap. Lower RMS error indicates that control points on the basemap and georeferenced map are closely aligned. However, alignment error may still be present in maps with a low RMS error.
  • Comparing the measure of the scale bar to the same distance measured on the base map, if present.

Integration Features

Georeferenced maps from Geofacets may be downloaded in GeoTIFF, KMZ, or shapefile format directly from your web browser, then integrated into essential workflow tools like ArcGIS™, the Petrel* platform, Google Earth™ or PowerPoint®. Tables can be downloaded as XLSX files for integration into Excel®, and figures can be downloaded as TIFFs for integration into PowerPoint or GIS software (after further formatting).

The Geofacets Connector for Petrel* and Studio allows the features and functionality of Geofacets to be available within the Petrel* platform. Without ever leaving Petrel*, the Geofacets Connector allows geoscientists to quickly access hundreds of thousands of georeferenced geologic maps extracted from trusted publications, gain more geologic insights for exploration projects and seamlessly integrate geoscience maps into 2D and 3D projects.
