This
laboratory focused on the use of GIS in assessing the spatial distribution and
types of crimes that occurred in Washington DC in August 2009. A table (*.csv
file) was downloaded that contained the type and the geographic coordinates of
crimes that occurred during the month. The data was exported to a shapefile such that
the crimes could be graphically displayed spatially. The Spatial Analyst Kernal Density was used
to quantify the concentration of particular crimes in the city. The density layer was then categorically
symbolized using the Natural Breaks classification scheme into five intervals.
