1. A method to enhance core analysis planning for core samples of subsurface material, the method comprising: positioning a plurality of electronic, two-dimensional, rectangular depictions of structure of one or more real, three-dimensional, cylindrical core samples of subsurface material in a side-by-side arrangement on a display, each of the one or more core samples having a first end and a second end, the second end of each of the one or more core samples associated with an original location within a corebore downhole relative to an original location within the corebore of the first end of the respective one of the one or more core samples, each core sample encased in a cylindrical container thereby to define an encased core, the plurality of depictions of structure of the one or more encased cores thereby to define a plurality of pilot images, each of the plurality of pilot images having a first end of the pilot image associated with the first end of the respective core sample depicted in the respective pilot image and a second end of the pilot image associated with the second end of the respective core sample depicted in the respective pilot image, the respective first end of each of the pilot images aligned along an imaginary line near an upper end of an electronic user interface; determining each of one or more portions of each of the plurality of pilot images as one of a plurality of planned sample types; and virtually marking each of the plurality of pilot images based on the determination.
