Module 5 produced two crime analysis maps for the Washington D.C. area. The first map displayed the comparison of crime rates to police station locations and, also the percentages of crime that any one station was responsible for handling. Based on these factors, two new police stations have been recommended to reduce work load on those high volume stations and to reduce the amount of crime in that given area (since it was in the higher crime percentage radius). Overall, this map showed that D.C.'s highest occurrence of crime occurs in its central Northwestern corridor but the presence of police stations does lower the crime rate within a half mile radius of the station's location.
The second map looks at crime densities in relation to population densities in D.C. city blocks. It uses kernel density analysis with a radius of 1500 kilometers for homicides, burglaries, and sex abuse offenses. This map highlighted patterns for these three particular offenses.
Major tools used to create these maps involved the buffer, spatial join, and the display XY tools. The exercise also revisited creation of an address locator and usage of the field calculator which were taught in the Intro course. The kernel density tool and graph creation were new procedures and were utilized to visually present data in a succinct manner.
