Unit 10: Analyze Data for Homeland Security







This week I was asked to analyze data that was created during the previous weeks assignment. This was a very difficult assignment complicated further by frequent server crashes, program time outs and long tedious hours of analyzing. The first road block I came to was the time out and ultimately closing of ArcMap after trying to save edits to the GNIS layer. Not only did this absorb 3-4 hours of time it was very frustrating. The next problem I encountered was creating a buffer for this point. After using the buffer tool ArcMap would create a buffer but the layer would not display on the map even after using the "zoom to layer" function. I pressed on simply by displaying the buffers for the airports and then focused on the nearest airport to the NORAD point. I was then able to produce the map of the ingress and egress routes in the second deliverable without much problem although I was unsure if I was meant to display the routes for just this location or multiple sites. The next problem I encountered was creating surveillance points. When I loaded the coordinates of COUA_DEM_UTM13 the shapefile produced no coordinates. After working on the project for nearly 14 hours I did my best to assemble a map and turn in at least a partial final deliverable.

Unit 8: Crime Analysis


As shown above, crime is not deterred at all by the 1,000 foot drug free zone. In fact, juvenile crime is at it's highest around schools according to data. Additionally there were no schools without a crime committed within 1,000 feet of the school. Thomson Elementary school was the highest incidence reported with 169 criminal reports.
