Is content other than maps available in Geofacets?

Yes. The value of Geofacets lies not only in access to the maps included in Economic Geology, but also in access to the contextual information for the map made available in a full-text, read-only PDF of the associated journal article.

Why are some of the maps not georeferenced?

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-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

Can I integrate my own maps and data with Geofacets content?

Yes. You can integrate Geofacets content with your own proprietary data and maps by downloading and importing our maps from your search results into your GIS software.

Will I be able to get a PDF of a journal article that does not contain any maps?

No. Only journal articles with maps are included in Geofacets.
