GIS UNIT
BPD’s GIS Unit provides innovative solutions that solve spatial problems and support better informed decisions about Baltimore’s crime.
GIS Analytics
Police Calls Density Map
The aim of this map is to identify areas that produce high density of police calls, be it crime, arrests,
calls for service,
etc.
The sample map here identifies areas in the Central District which produced the maximun overdose
calls.
Change Detection
This map type compares two time periods to identify whether crime has been increasing or decreasing.
The example map depicts crimes changes in November compared to October.
Green indicates a decrease in crime, while purple indicates an increase.
Robberies Trends: Areas to Watch
A powerpoint presentation of the study of robberies in Baltimore City. The study conducted the robberies that happened in 2018 and lists out the areas of high probability.
Street Segments
This style of map depicts the amount of crimes (or any other kind of data) that occurred in each hundred
block at any given time.
The example depicts firearm incidents per hundred block to identify areas that
are affected most by gun violence.
Point Maps
These maps display individual events as points on a map.
The example shown here displays homicides
and shootings that have occurred within 500 feet of a major thoroughfare in order to identify effective patrol
routes.
Space Time Cube
This tool can aggregate your data into space-time bins which are displayed
as 3D blocks stacked on top of each other
representing a location and time frame. These bins can then be
used to visualize statistically significant areas over time by measuring them as
either "hot spots" (ex. statistically significant high crime area) or
"cold spots" (ex. statistically significant low crime area) over time.
