GGRA30H3 Lecture 11: Lecture 11
Document Summary
Ways you can measure the density of different phenomena"s. When talking about geographic data we are trying to figure out intrinsically where the phenomena is happing --> use the concept of density (or intensity) When there was cholera breakout the normal was no one dying from the disease to it going to countless number of people dying --> density changes, not only physical. The size of the regions having a uniformly dense data is unlikely. Clicker question #1: using kernel density, if i increase the size of the kernel, will the density a. Clicker question #2: using kernel density, if i increase the size of the kernel, will the resulting raster surface: a. smoother b. remain the same c. more variable. Clicker question #2 (answer): the answer is a, you are creating more commonality between the two kernel cells, causing it to smooth out ==> refer lecture slide picture of map.
