Quadrant Addressing or Quaddressing provides an intuitive and consistent way to make relative spatial references to an original, two dimensional artifact (primarily for documents such as a printed text, photographs, etc.) regardless of its size or shape, or whether the artifact is physical or digital. Quaddressing relies on imprecision to aid human judgement instead of relying on highly precise measurements of varying units across different types of documents, thereby greatly increasing the ease and efficiency of both recording and interpretation across all documents for both human actors and code.
