GradeBuddy is best used as a supplement to your own notes, not as a substitute.-Situation - the location of a place relative to human activities -Cognitive images - locational attributes imagined by individuals based on their own experiences, memory and knowledge -Distance oAbsolute - measurement in terms of kilometers or miles oRelative - is measured in terms of cost, time or effort to get from A to B oCognitive - distance in the eye of the beholder, based on points of view and perception oTobler's First Law of Geography -"Everything is related to everything else, but near things are more related that distant things"-Points to friction of distance concept - the inhibiting effect of distance on humanactivity - it costs time and money to traverse distance (a frictional point)oDistance - Decay -The closer things are, the greater interaction, the further away, less frequent interaction -Technology is disrupting traditional distance decay effects -Can also be understood as a cognitive concept -Space oAbsolute, relative, Cognitive -Absolute - often measured in terms of geometry. Space is not dynamic or fluid, but understood through mathematical relationships-Relative - a socio-economic or cultural space that links people through common ties No definitive boundaryEX. South in the US -Cognitive - measured in terms of emotions, values, and
