Elsevier has announced that, after careful consideration, they have decided to sunset Geofacets. As you know, the Millennium Edition member benefit was powered by Geofacets. Since Elsevier will no longer be able to develop or support this platform beyond this year, the last day to access Millennium Edition will be December 31, 2023.
All Fellows of the Geological Society can access Geofacets-GSL Millennium Edition as part of their membership until December 31st 2023.
Is Geofacets being discontinued from January 1st 2024?
Elsevier has announced that, after careful consideration, they have decided to sunset Geofacets. As you know, the Millennium Edition member benefit was powered by Geofacets. Since Elsevier will no longer be able to develop or support this platform beyond this year, the last day to access Millennium Edition will be December 31, 2023. We regret any inconvenience this loss may cause to you.

The total map count is 24,000 from books and journals published in the Lyell Collection from 2000 to the present.
Whilst the maps are not categorised by subject area and may appear in multiple categories you will find there are 18,400 categorised in Geology; 2,600 in Paleogeography; 2,300 in Geophysics; 1,600 in Geography; 1,600 in Hydrology/Hydrogeology; 1,400 in Oceanography; 300 in Pedology and 100 in Meteorology and Climatology.
Yes. The value of Geofacets-GSL Millennium Edition lies not only in access to the maps included in Lyell Collection journals and books, but also in access to the contextual information for the map made available in a full-text, read-only PDF of the associated article.
While all maps from Geofacets-GSL Millennium Edition are downloadable as TIFF or JPEG files, there are a few possible scenarios for why maps found in Geofacets-GSL Millennium Edition could not be georeferenced:
- If a map is hand-drawn with errors introduced, which is common to maps generated prior to the mid-1990's 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
Yes. You can integrate Geofacets-GSL Millennium Edition content with your own proprietary data and maps by downloading and importing our maps into external software programs. Download GeoTIFF files to integrate into a GIS program, KMZ files to integrate into Google Earth, and JPEG files to integrate into PowerPoint or similar presentation software.
Please note that not all maps are available as a GeoTIFF file or KMZ file.
Geofacets-GSL Millennium Edition users 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 may be accessed via the Detail Window.
Maps are available at a variety of scales, depending on the publication and maps the author chose to convey geospatial information.
Maps are extracted as is from the articles. The extracted maps will only have a key/legend if the original map contained one. Depending on map format, you may need to view the original image tab in the Detail Window or the original publication.
Georeferenced maps may be downloaded in GeoTIFF or KMZ raster image format. No content is available as vector data at this time.
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.
At present, the Geofacets-GSL Millennium Edition content base contains only English language publications.
Many publications in Geofacets-GSL Millennium Edition 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-GSL Millennium Edition depends on the geographic area of interest and the research publications that exist in that area.
No. Only articles with maps are included in Geofacets-GSL Millennium Edition.
