Macrostrat has emerged as the go-to resource for digital geological map and geologic column data.

There are two main reasons for this:

  1. Macrostrat currently contains voluminous geologic map and column data that cannot be accessed in aggregate anywhere else.
    • Over 300 different geologic maps, containing more than 2.5 million rock unit polygons covering the world, have been integrated into a single, unified, queryable environment in Macrostrat.
    • Additionally, more than 35,000 rock units from over 1,500 regional columns covering all of North America and limited other regions are publicly available.
  2. Macrostrat has a public "REST" application programming interface (API) that makes the full complement of data available in Findable, Accessible, Interoperable, and Reusable (FAIR) fashion with a CC-BY license.

Many third-party applications and users take advantage of Macrostrat data services:

  • Mancos
  • StraboSpot
  • Flyover Country
  • MinDat
  • The iNaturalist web and mobile applications
  • A California Academy of Sciences interactive museum kiosk
  • Local geological surveys and individual scientists.

Usage

Macrostrat’s data services have become impactful community resources for geologic information:

  • Our geologic map server has served more than 2 billion tile requests since logging began in 2018 (~10 per second)
  • Over the last 28 days, our other data APIs have served 3.8 million requests (~2 per second).
  • Conservatively, these amount to 100,000 requests for information each day.
