Abstract

A method for generating one or more maps of a survey area. The method includes receiving earth observation data, georeferencing the earth observation data with seismic data, extracting one or more attributes from the earth observation data and displaying the extracted attributes.

Claims

1. A method for generating one or more maps of a survey area, comprising:

receiving earth observation data;

georeferencing the earth observation data with seismic data;

extracting one or more attributes from the earth observation data; and

displaying the extracted attributes.

2. The method of claim 1, wherein displaying the extracted attributes comprises plotting the extracted attributes on the maps.

3. The method of claim 1, further comprising calibrating the extracted attributes with seismic quality control data.

4. The method of claim 1, wherein the attributes comprise a digital terrain model.

5. The method of claim 4, wherein the attributes further comprise land use information.

6. The method of claim 4, wherein the digital terrain model provides a topography and surface gradient of the survey area.

7. The method of claim 4, wherein the digital terrain model is extracted from the earth observation data obtained from at least one of visible, near and mid infrared light.

8. The method of claim 5, wherein the land use information are extracted from the earth observation data obtained from at least one of visible, near and mid infrared light.

9. The method of claim 5, wherein the land use information comprise information regarding at least one of infrastructure, vegetation, rivers and mountains.

10. The method of claim 5, wherein the land use information and the digital terrain model are indicative of safety and accessibility of the survey area for seismic data acquisition.

11. The method of claim 1, wherein the attributes comprise information regarding rocks, each with a diameter greater than about 20 cm.

12. The method of claim 11, wherein the information regarding rocks are extracted from the earth observation data obtained from short wave infrared light.

13. The method of claim 11, wherein the information regarding rocks is indicative of locations within the survey area that are conducive to vibrator coupling and point loading problems.

14. The method of claim 1, wherein the attributes comprise information regarding soft ground.

15. The method of claim 14, wherein the information regarding soft ground comprises information regarding at least one of drainage patterns, wadis, sand dunes, sabkha, gypsum marshlands, and caliche horizons.

16. The method of claim 14, wherein the information regarding soft ground is extracted from the earth observation data obtained from short wave infrared light.

17. The method of claim 14, wherein the information regarding soft ground is extracted from the earth observation data obtained from thermal infrared light.

18. The method of claim 1, wherein calibrating the extracted attributes comprises correlating the extracted attributes with at least one of force and distortion information of the source signals and at least one of characteristic surface wave velocity, attenuation, resonance, magnitude and spectral characteristic of the receiver signals.

19. The method of claim 1, wherein the maps comprise a visible light image map illustrating land use information within the survey area.

20. The method of claim 1, wherein the maps comprise a roughness map illustrating information regarding rocks with a diameter exceeding 20 cm.

21. The method of claim 1, wherein the maps comprise a surface lithology map illustrating soft ground information within the survey area.

22. A method for planning a survey, comprising:

receiving earth observation data;

georeferencing the earth observation data with seismic data;

extracting one or more attributes from the earth observation data;

displaying the extracted attributes; and

using the maps to identify locations within the survey area that are prone to ground coupling problems for source and receivers.

23. The method of claim 22, wherein displaying the extracted attributes comprises plotting the extracted attributes on the maps.

24. The method of claim 22, further comprising calibrating the extracted attributes with seismic quality control data.

25. The method of claim 22, further comprising using the maps to identify unsafe and inaccessible locations within the survey area.
