Geographers have all studied representation, through cartography, statistics, and textual description. A portfolio is a representation of your professional capability – a more multimedia and multi-dimensional representation than a résumé.
§ Multimedia, because it can include more than words on paper – photographs, maps, websites, brief aural examples can be included (easier if the portfolio is electronic) or referenced.
§ Multidimensional, because it addresses not only skills and accomplishments, but how you have gained those skills and accomplishments and what impact your actions have had on people and organizations.
