Document Summary
Space = areal extent or the extent (amount) of area on the earth"s surface: absolute space any area. Objective, physically real, with measureable extent and definable boundaries. Key for map-making (used for generating maps of the world), description. Mathematical projections used to transform 3d sphere into 2d map (things need to be adjusted to maintain value of absolute space) e. g. mcmaster campus - 50 acres (measureable, size); main st west, Relative positioning & importance: topological map. Subway map not accurate, placed in a way that is relative to one another, what matters is where the next stop is: sketch maps: scale, distance & positioning are guesstimates. Location: refers to a particular position in space: absolute (mathematical) location: latitude & longitude co- ordinates using an arbitrary mathematical grid: 80 w, 43 n. Latitude & longitude: lines allow us to identify any position in precise terms (topographic maps: relative (perceived) location: a short drive from downtown, or adjacent to cootes.
