Week 10-Protect

The map below shows the points into and out of the Cheyenne Mountain Heliport 500 ft buffer. Knowing the location of these points is important because it will allow surveillance of who enters and exits the vulnerable infrastructure.

This week's subject was based on homeland security. This week I learned that GIS can be used to locate areas that are vulnerable to terrorist attacks. In the map above, I used ArcMap to form a 3mile buffer around NORAD and a 500 ft buffer around the Cheyenne Mountain Heliport. NORAD and the heliport are considered "critical infrastructure" and are high risk for terrorist attacks. These maps were fairly straightforward and easy to create. I had quite a bit of trouble on the other two deliverables. I had trouble keeping file names organized. I was also confused on which files to use, especially in ArcScene.

Week 8 Washington DC Crimes

Below is a basemap of the Washington DC area. It shows the major hignways, the crime dispersal, and police station. The chart tells how many and what type of crimes were committed in the area.

The map below shows distances from police stations and the crimes committed around them. I noticed that there is a cluster of crimes in the southern part of the state. These crimes happened more than 2 miles away from a police station. I would recommend a new station be placed in this area.

The map below shows where concentrations are higher for different crimes in DC. The areas with higher densities of crimes are a darker color.

The maps below show the density of auto thefts in DC. The chart shows the number of total crimes that happened during each hour of the day. Auto thefts have a higher density during the evening hours. All other crimes have a higher density during evening hours, as shown in the chart.
