    Identifying and classifying historic, forgotten or undocumented pathways in Forest Park

    There is a tendency for many people to look at the lush Forest Park and see the park as an example of a primeval forest, a true wilderness. However the City of Portland’s Forest Park has been imprinted by many generations of people using it for purposes ranging from survival subsistence/living quarters and industrial resource extraction to recreation and contemplation.

  • The Sense of Place

    What is the sense of place?

    It is a combination of characteristics that makes a place special and unique. Sense of place involves the human experience in a landscape, the local knowledge and folklore. Sense of place also grows from identifying oneself in relation to a particular piece of land on the surface of planet Earth.

  • The Octant Projection

    In the early 1500's Leonardo da Vinci (or an assistant under his direction) created the "octant map," a mappa mundi which splits the globe into eight sections or petals. Each petal is called a Reuleaux triangle--created by joining three equal-length circular arcs into an equilateral triangle. Each cluster of 4 petals covers one hemisphere of the earth.

    In terms of cartographic qualities, this projection is neither conformal or equal area†. More so than most projections (Mercator, Peters, Miller Cylindrical, Hobo, etc.), the shape is visually appealing.
