Abstract

A method for generating one or more maps of a survey area. In one implementation, the method may include receiving earth observation data, decomposing the earth observation data into pixels, georeferencing the earth observation data in pixel form with the curvature of the earth'"'"'s surface, integrating the earth observation data in pixel form with seismic data, extracting one or more attributes from the integrated data and displaying the extracted attributes on one or more survey maps.

Claims

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

receiving satellite imagery data-of the survey area;

decomposing, via a system computer, the satellite imagery data into pixels, wherein at least one pixel represents a plurality of image values from the satellite imagery data;

integrating the satellite imagery data in pixel form with seismic data;

extracting one or more attributes from the integrated satellite imagery data; and

displaying the extracted attributes on one or more survey maps on a display device.

2. The method of claim 1, further comprising georeferencing the satellite imagery data in pixel form with the curvature of the earth'"'"'s surface prior to integrating the satellite imagery data in pixel form with seismic data.
