Abstract: A loupe apparatus includes a support, a post coupled to the support, and a lens holder rotatably coupled to the post. The lens holder is rotatable around an axis of the post. The lens holder includes an arm, an extension coupled to the arm with a ball and socket joint, and a lens coupled to the extension.

Abstract: A loupe apparatus includes a support including a nose bridge and a support arm, a post coupled to the support, a first lens holder rotatably coupled to the post, and a lens attachment detachable coupled to the support arm of the support. The lens holder is rotatable around an axis of the post. The lens holder includes a holder arm, an extension coupled to the holder arm, and a lens coupled to the extension. The lens attachment including a second post and a second lens holder rotatably coupled to the second post. The second lens holder including a second lens.

Abstract: A method including obtaining a first image of a geographical location and a physical object located therein. Pixels in the first image are assigned to corresponding points in a Cartesian coordinate system defined specifically for the first image. The resulting virtual map includes a virtual representation of the physical object, a set of Cartesian coordinates assigned to a set of pixels in the pixels, and a set of Cartesian rotation angles assigned to the set of pixels. A first transform is calculated that scales the Cartesian coordinate system to a physical scale of the geographical location. A data structure stored in a data repository is formed by applying the first transform to the virtual map. The data structure includes the set of pixels, a set of scaled Cartesian coordinates, the set of Cartesian rotation angles, and a physical scale virtual representation of the physical object.
