Abstract

A device comprises a processor; and a memory device including instructions that, when executed by the processor, cause the processor to: obtain, from a server, a plate model, wherein the plate model includes a plurality of geodynamic units (GDUs) representing a plurality of different geological regions; receive a user-defined geospatial data of a desired geological region; perform an intersection operation between the user-defined geospatial data and the plurality of GDUs of the plate model, to assign user-defined geospatial data a GDU identifier; obtain, from a server, Euler rotation poles based on a user-specified geological age, each Euler rotation pole being associated with a GDS via the GDU identifier; and reconstruct the user-defined geospatial data to the geological age using the Euler rotation pole and thereby obtain a reconstructed paleogeographic position of the user-defined geospatial data.

First claim

What is claimed is:

1. A device comprising:
a processor; and
a memory device connected to the processor, the memory device including instructions that, when executed by the processor, cause the processor to:
obtain, from at least one server accessed over a network, a plate model, wherein the plate model includes one or more geodynamic units (GDUs), each GDU including a GDU identifier, each GDU representing a different geological region;
receive a user-defined geospatial data of a desired geological region;
perform an intersection operation between the user-defined geospatial data and the plurality of GDUs of the plate model, the intersection operation assigning one of the GDU identifiers to the user-defined geospatial data;
obtain, from at least one of the servers, one or more Euler rotation poles, each Euler rotation pole based on a user-specified geological age, each Euler rotation pole being associated with one of the GDUs via the GDU identifier of the associated GDU; and
reconstruct the user-defined geospatial data to the user-specified geological age using the Euler rotation pole for the user-specified geological age at the assigned GDU identifier, the reconstruction a reconstructed paleogeographic position of the user-defined geospatial data at the user-specified geological age.

2. The device of claim 1 , wherein the instructions further cause the processor to:
provide the reconstructed geometry to facilitate exploration of a desired natural resource.

3. The device of claim 1 , wherein the instructions further cause the processor to:
display the reconstructed paleogeographic position of the user-defined geospatial data for the user-specified geological age.

4. The device of claim 1 , wherein the instructions further cause the processor to:
store the reconstructed paleogeographic position of the user-defined geospatial data for the user-specified geological age as a geographic information system (GIS) file.

5. The device of claim 1 , wherein the instructions further cause the processor to:
validate the user-defined geospatial data to determine whether the user-defined geospatial data is correctly defined, to determine whether a reference coordinate system used for user-defined geospatial data is correct, or to ensure that latitude and longitude values in the user-defined geospatial data are valid.

6. The device of claim 5 , wherein the instructions further cause the processor to:
store the validated user-defined geospatial data and the GDUs obtained from the plate model in the memory device.

7. The device of claim 1 , wherein the instructions further cause the processor to:
correct geometrical errors in the reconstructed geometry due to the +/−180° longitude dateline or Earth's North/South poles (+/−90 latitude).

8. A method, comprising:
obtaining, from at least one server accessed over a network, a plate model, wherein the plate model includes one or more geodynamic units (GDUs), each GDU including a GDU identifier, each GDU representing a different geological region:
receiving a user-defined geospatial data of a desired geological region;
performing an intersection operation between the user-defined geospatial data and the plurality of GDUs of the plate model, the intersection operation assigning one of the GDU identifiers to the user-defined geospatial data;
obtaining, from at least one of the servers, one or more Euler rotation poles, each Euler rotation pole based on a user-specified geological age, each Euler rotation pole being associated with one of the GDUs via the GDU identifier of the associated GDU; and
reconstructing the user-defined geospatial data to the user-specified geological age using the Euler rotation pole for the user-specified geological age at the assigned GDU identifier, the reconstruction a reconstructed paleogeographic position of the user-defined geospatial data at the user-specified geological age.

9. The method of claim 8 , further comprising:
providing the reconstructed geometry to facilitate exploration of a desired natural resource.

10. The method of claim 8 , further comprising:
displaying the reconstructed paleogeographic position of the user-defined geospatial data for the user-specified geological age.

11. The method of claim 8 , further comprising:
storing the reconstructed paleogeographic position of the user-defined geospatial data for the user-specified geological age as a geographic information system (GIS) file.

12. The method of claim 8 , further comprising:
validating the user-defined geospatial data to determine whether the user-defined geospatial data is correctly defined, to determine whether a reference coordinate system used for user-defined geospatial data is correct, or to ensure that latitude and longitude values in the user-defined geospatial data are valid.

13. The method of claim 12 , further comprising:
storing the validated user-defined geospatial data and the GDUs obtained from the plate model.

14. The method of claim 8 , further comprising:
correcting geometrical errors in the reconstructed geometry due to the +/−180° longitude dateline or Earth's North/South poles (+/−90 latitude).

15. A non-transitory computer-readable medium including instructions stored therein that, when executed by at least one computing device, cause the at least one computing device to:
obtain, from at least one server accessed over a network, a plate model, wherein the plate model includes one or more geodynamic units (GDUs), each GDU including a GDU identifier, each GDU representing a different geological region;
