Have an assigment due at 12:00 PM. It is to create two maps to the specifications I’ve uploaded. I can supply the files necessary as well.
J426MAPPING & ANALYSIS FOR PUBLIC SAFETY (SPRING 2013)
Assignment 7: Density and Hot Spot Analysis
Due at 11:59 p.m. Monday, April 22
IMPORTANT NOTE: This assignment will require the use of the CrimeStat program. If you want
to use this outside of BS 1000, you will need to download and install the program. The link to do
so is follows:

For this assignment, you will be creating maps showing the generalized distribution of crimes
using crime density maps and will be using the CrimeStat program to do hot spot analysis. All of
the data files you will be using for this assignment can be found in various subfolders of the
J426Files folder on your flash drive.
Save the map files you create to the folder MapFiles on your flash drive. Save the data files you
create to the folder DataFiles on your flash drive.
The general instructions provided at the start of Assignment 2 also apply to this assignment:
The maps should be finished products, well-designed, with all of the elements associated with a
complete finished map. These include:
Title(s)
Scale(s)
North arrow(s)
Legend(s) where needed (with reasonable headings, as appropriate)
Your name, as creator of the map
Neatline(s)
In grading these maps, points will be awarded for quality of presentation or will be deducted for
lack thereof.
In providing instructions for the maps you are to be creating, the focus will be on the primary
subjects of the maps. The choice of additional layers to be used as reference geography will not
be addressed in detail. A number of files that might be used for reference geography are
included in the J426Files\Basemap folder.
When creating the crime density maps, remember to make your final crime density layers
permanent, saving these to the DataFiles folder. Failure to do so will result in your losing your
work. Also, remove those crime density layers that you do not want to keep from your map
before saving the map.

Map 1
For this map, you will be creating two crime density maps, one for robberies and one for
aggravated assaults, for 2002.
Data for this Map:
You will use the table UCR2002.dbf with the Uniform Crime Report crimes for 2002. This
table has the x- and y-coordinates for the crimes.
You will have to select out the individual types of crimes to create new layers or files for
the robberies and aggravated assaults.
The maps you create must have the following characteristics:
You will create two crime density maps. The first showing the generalized patterns for
the robberies and the second for the aggravated assaults.
Be sure to specify search radii that emphasize the broader, generalized patterns of the
crimes, not small clusters.
Use the same radius for the both maps (robberies and aggravated assaults).
Display these side-by-side on the finished map.
Remember: the inclusion of some reference geography (not necessarily a reference map) will
help the viewer better understand locations within the map.
Map 2
For this map, you will be creating two hot spot maps (using CrimeStat), one for robberies in
2002 and one for robberies in 2003.
Data needed for this map:
For the 2002 robberies, you will use the same data you used for Map 1.
For the 2003 robberies, use the file Robberies2003.dbf.
Required Maps:
Create two hot spot maps for the robberies in each of the two years.
You may use your discretion regarding the method of hot spot analysis and the
parameters for the analysis.
But be sure to use the same method and the same parameters for both years.
Display these maps side-by-side on the finished map.
Include the robbery points for each year on the respective hot spot map, making sure
that the points are very small so they do not obscure the hot spots.
