GPHY384 Lecture 1Intro 1/14/16 +In GPHY284 learned about the power of maps, now about the power of thinking spatially +5W’s of Geography 1. What is where? 2. When is it there? Geologic data doesn’t change much, vegetation changes a little bit more often, and Cadastral data (land ownership) changes a lot! SpatioTemporal Modeling model changes through space and time \ 3. Why is it there? / How is it there? 4. Who cares? Why are we being paid to map it? 5. Why do I care? +Not a software training class: want to learn to solve realworld problems +Example: GIS can be used to manage a drought monitor using spatiotemporal information because it changes so rapidly +Use datasets to create maps to map drought use smoke area and severity of fire data sets (keep scale in mind) +5 different measurement scales beyond qualitative and quantitative: 1. Nominal categorical/qualitative land use (range or urban) 2. Ordinal ranked order low high 3. Interval relative location on a linear scale, no point of origin temperature, years 4. Ratio relative on a linear scale with a fixed point of origin elevation (sealevel) 5. Cyclic direction + Snow Water Equivity (SWE) will estimate how much water there will be in the spring based on snow melt +GIS Geographic Information Sciences How to collect, manage, process, and analyze geospatial data to communicate info about realworld problems Need to be able to think critically
