Maps and Other Content

Geofacets contains 600,000+ maps (over 70% georeferenced) and 160,000+ tables sourced from geoscience publications from esteemed 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

Table content is sourced from selected journal publications for select publication dates. Each map contains a link to a read-only PDF of the source article, along with a link to the publisher’s website to download, share or print the article. As the journals included in Geofacets publish new articles featuring maps and tables, we update Geofacets with these maps and tables on an ongoing, monthly basis. Geofacets only contains articles that have maps and/or tables. Maps are downloadable into GeoTIFF, GeoTIFF + Metadata, KMZ, JPEG, TIFF, and Shapefiles (for select content). Tables are downloadable into XLSX 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 can be discovered along with associated maps in the map detail window.

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 associated data 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.

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, including restrictions on republishing the original or modified maps. 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 maps weekly as new journal volumes are published.

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

Many publications in Geofacets contain geological cross-sections. However, cross-sections are not available as an extracted image at this time. Users can refine search results to the map types: Structural, Stratigraphic Units/Deposits, Seismic Survey and Borehole/Corehole Location as geological cross-sections are frequently located in the associated publications for these map types. Users can also perform a keyword search or keyword refinement for "cross section".

The ability of a user to create cross-sections or other geological interpretations from Geofacets depends on the geographic area of interest and the research publications that exist in that area.

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®.

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. Tables are downloadable and can be integrated into GIS software (e.g., if coordinates are available in the table or in the associated maps).

*trademark of Schlumberger

Geofacets has a limited amount of vector data via shapefiles. All of Geofacets' shapefile content is only available within Mexico and the Mexican Gulf at this time.
