00:00:04,500 --> 00:00:06,930
Let me comment on the
merits of heatmaps

2
00:00:06,930 --> 00:00:10,710
as a way of representing data
in the context of representing

3
00:00:10,710 --> 00:00:12,660
crime activity.

4
00:00:12,660 --> 00:00:14,350
Criminal activity-related
data often

5
00:00:14,350 --> 00:00:17,200
has both components
of time and location.

6
00:00:17,200 --> 00:00:20,880
Sometimes, all that is
required is a line chart,

7
00:00:20,880 --> 00:00:23,180
but heatmaps can
visualize data that

8
00:00:23,180 --> 00:00:25,190
will be too big for a table.

9
00:00:25,190 --> 00:00:28,070
Plotting data on maps
is much more effective

10
00:00:28,070 --> 00:00:33,900
than a table for location based
data, and is eye catching.

11
00:00:33,900 --> 00:00:36,560
What is the edge of
predictive policing?

12
00:00:36,560 --> 00:00:39,970
Many police forces are
exploiting their databases

13
00:00:39,970 --> 00:00:44,020
to focus finite resources
on problem areas.

14
00:00:44,020 --> 00:00:47,720
Not only do analytics
help improve policework,

15
00:00:47,720 --> 00:00:50,940
the outputs are also
good communication tools

16
00:00:50,940 --> 00:00:53,590
to decision makers in
government, and the wider

17
00:00:53,590 --> 00:00:54,690
public.

18
00:00:54,690 --> 00:00:58,210
The application of
analytics to data like this

19
00:00:58,210 --> 00:01:01,180
is new and growing,
with companies

20
00:01:01,180 --> 00:01:06,790
like PredPol and Palantir
leading the effort.
