Features:
1. We plot crime locations with our patented* 3 dimensional
stacked symbols in Google Earth®, with streets and satellite image in the background.
2. The plot is based on your jurisdiction's crime data. We can plot up to three
hundred thousand (300,000) records.
3.
Each location is plotted with a stack of symbols. The number of
symbols in a stack corresponds to the number of crime incidents at that location. This
provides a three dimensional view, such that the height of the symbols is
proportional to the number of crime incidents.
4. The symbols within a stack have different letters and colors,
representing different crime types. For example, a yellow
"A" symbol represents auto theft; a green "B" symbol
represents burglary; and so on.
5.
By looking at the heights and colors of the symbols, you have an overview of how
many, what type and where are the crimes.
6. When you click a plotted symbol, it displays the contents of a record
from your data. You can filter out contents related to privacy, such as name,
date of birth, telephone number, etc. from being displayed, if it is for public
view.
7. It has the built-in capability of displaying
a scanned image of the crime incident report. This allows
you to refer to the original data easily. More...
8. It has the built-in capability of attaching a memo to a plotted symbol.
Since each plotted symbol is associated with a crime record, it allows you
to add related information to a crime record. For example, if the crime incident
is an on-going investigation, you can continue to add comments and notes to the
crime record. More...
9. It has the built-in capability of attaching an image to a plotted symbol.
Since each plotted symbol is associated with a crime record, it allows you
to add a picture of the crime scene, or a scanned court report, etc. to a crime record. More...
10. It has the ability to add HTML tags, using Google Earth's built-in functions.
The reason you can do this is that when the contents of a record is displayed in Google Earth,
it is displayed in a browser. A browser has many capabilities, including the
capability of using HTML tags. You can use HTML tags, such as <a>, <a
href>, <img src>, etc. to add additional links and files to associate
with a plotted symbol. Since each plotted symbol is associated with a crime
record, hence you can add additional links and files to each crime record. These
links and files include web pages, executable programs, images, sounds, videos, etc. These links
and files may be in the internet or in your local computer. For example, you may
add links to other criminal records, court records, gun registration records,
etc.
The built-in capabilities
of displaying a scanned image of the crime incident report, attaching a memo, and attaching an image, as
mentioned in items 7, 8 and 9, are just special applications of adding
HTML tags. You can add almost an unlimited number of tags to link to
almost an unlimited number of resources.

Figure 1: Crime Locations From Washington, DC's 2007 Data
This figure shows how a typical plot of crime locations looks like in
Google Earth®.
Each location is plotted with a stack of symbols. The number of
symbols in a stack corresponds to the number of crime incidents at that location. This
provides a three dimensional view, such that the height of the symbols is
proportional to the number of crime incidents.
The symbols within a stack have different letters and colors,
representing different crime types. For example, a yellow "B" symbol represents
burglary.
Figure 1 is based on Washington DC's 2007 crime
incident data*. The data have about 35,000 records
and 8,000 crime locations. Figure 1 shows some of the crime
locations to the north and east of the Monument.
*Data Source: http://data.octo.dc.gov/Main_DataCatalog_Go.aspx?category=6&view=All

Figure 2: Top 10 Crime Locations From Washington, DC's 2007 Data
This figure is similar to Figure 1, except that (a) it shows the top 10 crime locations
in Google Earth® and (b) it views from a higher altitude.*.
*Data Source: http://data.octo.dc.gov/Main_DataCatalog_Go.aspx?category=6&view=All
|
Figure 3: Showing Different Symbols For
Different Crime Types
 This
figure shows that when you zoo-in, the symbols within a stack become
farther apart, enabling you to see the letters and colors of the symbols.
For example, a yellow "B" symbol represents burglary.
A legend about the symbols can be found in
the left hand side under "Places" in Google Earth®.
|
Figure 4: Displaying Contents Of A Record, When Clicking A Plotted
Symbol
When you click a plotted
symbol, it displays the field names and field contents of a record, as
shown in this figure. You may choose which fields to be displayed.
This enables you to examine detail individual
records while having an overview of all crime locations at the same time.
|
Figure 5: Displaying Crime Report Image After Clicking A Plotted
Symbol
When you click a plotted
symbol, it displays a hyperlink called "Report Image ...".
When you click this hyperlink, it displays the scanned crime report image, as shown
here.
This enables you to examine the original data
of an individual crime while having an overview of all crime locations at the
same time.

*The second set of plots is the same as the first set except that it displays
limited contents from the data. For example, you may use the first set for
internal use and the second set for public use. In the first set, you may
specify all fields from data to be displayed when user clicks a plotted symbol.
In the second set, you may specify only limited fields, such as date, time,
crime type, etc. to be displayed when a user clicks a plotted symbol. You may
upload the second set to your web site for public access.

How It Works:
1. In order to plot crime locations in Google Earth®,
your data must contain location information. Location information may be latitudes and
longitudes; addresses; main street names and cross street names;
distances and directions from nearest intersections; etc. If the
location information are not in latitudes and longitudes, we will geocode them.
That is, we will convert the location information into latitudes and longitudes.
We will use either your latitudes and longitudes, or the converted latitudes and
longitudes (based on your other location information) to identify the locations
in Google Earth®.
2. To start working for you, we will ask you to email some or all your data
to us. This is to make sure that your data have the proper location information.
(We accept data with almost any data structure and coding definitions.) Save you data in one of the following file formats:
- Access (MDB)
- ASCII or Text (TXT), with tab or
comma as delimiter
- Comma Separated Values (CSV)
- dBASE (DBF)
- Excel (XLS)
- XML
3. If you are not sure what data, or your data cannot be saved in one of the
formats listed in 2, please send some of
the daily crime incident reports that you release to the public, in whatever
format. We will be happy to look at them to determine if they have the proper
location information and or format.
4. If your data do not have the proper location information, we will discuss
with you to see if there is alternative. If there is no alternative, we will not be able to take your order.
5. If your data have the proper location information, we will ask you to send
us all your data and payment/purchase order.
6. We will create the crime
locations plot for you, similar to the ones shown in Screen Shots above. We will save the
plot in a KMZ file and
will send it to you.
7. Upon receiving the KMZ file, you can save it
anywhere in your computer. When you double click the KMZ file, it will display
the crime location plots as shown in the Screen Shots above, if you have
installed Google Earth® on your computer. You may use the KMZ file for any purpose, including
emailing to others, uploading and posting in your web
site, etc. If you post the KMZ file in your web site, when a visitor clicks the
KMZ file link in your web site, the visitor will see the same display as shown
in Screen Shots above, if the visitor has installed Google Earth® in his/her
computer (see
How To Display In Web Site below).
8. You may consider ordering two sets of KMZ file.
The first set is for internal use. The second set is for public use and/or for
posting in your web site. Both sets are plotted from the same data and displaying
the same symbols at the same locations. The differences are as follows:
a) The internal-use set:
- When you click a plotted symbol, it displays
everything from your data.
- When you click a plotted symbol, it displays a link to a scanned image of the crime incident report. When
you click this link, you can see the original report form. More...
- When you click a plotted symbol, it displays a link to a memo file. When you
click this link, you can see the attached memo. More...
- When you click a plotted symbol, it displays a link to an image file. When you
click this link, you can see the attached image file. More...
- As a result, you can use this set for policing, crime analysis and crime data
management.
b) The public-use set:
- When one clicks a plotted symbol, it displays only limited information from your data. (You can specify which information to
display.)
- When one clicks a plotted symbol, it displays a link to a scanned image of the crime incident report. When one clicks this link, it will
say unavailable.
- When one clicks a plotted symbol, it displays a link to a memo file. When one
clicks this link, it will say unavailable.
- When one clicks a plotted symbol, it displays a link to an image file. When
one clicks this link, it will say unavailable.
- As a result, you can use this set for public
awareness.
The price for the second set is 30% of the first set.
8. Delivery of product will be about one week, after we have
received your data and payment/purchase order. 2-day delivery and next-day
delivery are available with additional cost.

How To Display In Web Site:
1. Using your data, we plot the crime locations and save them in a KMZ file
(see How It Works).
2. Upload the KMZ file to the sever in your web site, then create a
link in a web page to link to this KMZ file.
3. Ask the webmaster to set the web site's MIME type for KMZ file, such as
setting the httpd.conf file to:
application/vnd.google-earth.kmz
.kmz
For Apache, add this line to the
httpd.conf file:
AddType application/vnd.google-earth.kmz .kmz
For more information, see http://code.google.com/apis/kml/documentation/kml_tut.html
or http://earth.google.com/support/bin/answer.py?answer=25094&topic=13334
4. That is it! When a person in the Internet goes to the web page and clicks the link, it will
display the stacked symbol crime location plots, similar to those as shown in
figures 1 to 4 under "Screen Shots."
