Calculate Paleo-geographic Coordinates

Description:

Reconstruct the geographic locations from present day coordinates back to their paleo-positions. Each location will be assigned a plate id and moved back in time using the chosen reconstruction model.

Endpoint:

https://gws.gplates.org/reconstruct/reconstruct_points

Parameters:
  • points

    The present-day coordinates of locations in longitude and latitude separated by ','.

  • time

    The geological age in million years(Ma) to which the coordinates will be reconstructed. The valid input value depends on the chosen reconstruction model.

  • model

    The reconstruction model name.

Models:
  • "default" -- The valid time range is between 0 and 440.
Return:

Paleo-coordinates in GeoJson format.

Example:

The URL below reconstructs two locations((lon:95,lat:54)(lon:142,lat:-33)) back to 140 million years ago using the "default" reconstrution model.

Reconstruct Feature Collection

Description:

Reconstruct feature collection in GeoJSON format back in time. Each feature will be assigned a plate id and moved back in time using the given reconstruction model. Reconstructed features will be returned in GeoJSON format.

Endpoint:

https://gws.gplates.org/reconstruct/reconstruct_feature_collection

Parameters:
  • feature_collection:

    The feature collection in GeoJSON format.

  • geologicage:

    The geological age in million years(Ma) to which the feature collection will be reconstructed. The valid input value depends on the chosen reconstruction model.

  • model:

    The reconstruction model name.

Models:
  • "default" -- The valid time range is between between 0 and 440.
Return:
  • Feature collection in GeoJson format.
Example:

https://gws.gplates.org/reconstruct/reconstruct_feature_collection/?feature_collection={"type":"FeatureCollection","features":[{"type":"Feature","geometry":{"type":"Polygon","coordinates":[[[23,-20],[-9,35],[14,44],[23,-20]]]},"properties":{}}]}&geologicage=140&model=SETON2012
