This document provides instructions for cleaning raw crime data and mapping it using Google Fusion Tables. The steps include cleaning the data by deleting unnecessary columns and categories, formatting the location data and adding an icon column with codes corresponding to each crime type. The cleaned data is then uploaded to a new Google Fusion Table which is styled and shared publicly. An embeddable link is generated to display an interactive map visualizing the crime data.

6. Creating a crime map from raw data:
Cleaning the data:
Delete columns E (Disposition) and F (inc-no).
Rename column C “Type of call”.
Double click to expand columns C and D.
Click Column C, go to Data, and sort A-Z. (Make sure that my list has
header row is clicked)
Keep the following categories: Auto Burglary, DUI, Fraud, Grand Theft
Auto, Garage Burglary, Hit and Run, Homicide, Residential Burglary,
Robbery, Shots Fired, Vandalism. Delete the rest.

7. Making it work for Fusion Tables (This is where it gets a bit confusing …)
In E2 paste in: =D2&" Alhambra, CA"
(Note: Make sure there is a space in front of Alhambra)
Cell should now read location with Alhambra, CA. Drag to bottom of column.
Select entire column E and copy. Go to edit and click “paste special” and
choose value. Paste in the same column.
Delete D column.
On Column D (Location) Do find Find “/” and replace ALL with “&”. (Note: this is
necessary for Google maps to read intersections.)
Create new E column, titled “Icon”. (Note: The order of columns should now
read: A= Date, B=Time, C=Location, D=Type of Call, E=Icon)

8. There are two ways to fill in the info needed for the icon column. Depending on
how much data there is, using a single code might be easier.
Copy in the following code to E column and then drag to bottom:
=IF(D2="AUTO BURG RPT","blu_blank",IF(D2="GRAND THEFT
RPT","orange_blank",IF(D2="HIT AND RUN","purple_blank",IF(D2="RESID
BURG RPT","wht_blank",IF(D2="RESIDENTIAL
BUR","wht_blank",IF(D2="VANDALISM","ylw_blank",IF(D2="VANDALISM
RPT","ylw_blank",IF(D2="FRAUD","grn_blank",IF(D2="GARAGE BURG
RPT","wht_blank",IF(D2="ROBBERY","ltblu_blank",IF(D2="ROBBERY
RPT","ltblu_blank",IF(D2="SHOTS
FIRED","pink_blank",IF(D2="HOMICIDE","placement_circle_highlight",))))))))
)))
To select your own icons, Google “google fusion tables icons”.
Select first link, click Visualize, then Map.
Select desired icons, copy code for icon or icon name.
Paste the code into the Icon column.
Drag down to cover all corresponding categories in D column.
Repeat using different icons for each crime.

9. Creating Google fusion table from the cleaned data:
Open Google Docs in gmail.
Click “Create” button and “Table”
Upload .csv file, hit next (2x)
Table name: write month of crimes.
Attribute Data: write “Alhambra Police Department” and finish.
Next page will be the data, location should be in yellow if it is geocoded, if it
isn’t. click “edit” “location” and make sure type says “location”.
Go to Visualize and select Map.
Click “Configure info window” and unclick “icon”.
Click “Configure map styles” and select Column, and in drop menu select
“icon”.
Go to Share, and select “Public”.
Click “Get embeddable link”. Change zoom to “z=13”.
Copy the link. Now ready to embed finished Google Fusion table!!!!
