Online Crime Maps

What is is an online mapping and analysis service provided by Public Engines, Inc., headquartered in Salt Lake City, Utah. It combines the value of police data with the ease-of-use of Google-based mapping and an analytics module so that members of the public can view police data in a high-impact map or summary descriptive format. Members of the public may also sign up to receive free email alerts based on user-defined parameters (e.g., geography, crime types, frequency, etc.).

What type of UCLA Police Department (UCPD) data is used in

The service utilizes report data from the UCPD Records Management System (RMS). RMS is a highly specialized application that allows for the coordinated communication, assignment, and tracking of Police Department reports.

What specific types of data from RMS are used in

Report data is utilized for, including the following data fields: report numberdate and time occurred, location, and nature of crime.

Is there a description for the RMS data fields included in

Yes. This includes:

  • Report Number: Electronically generated by the Police Department’s RMS system, this number catalogues all police reports. The report number consists of six numbers. In the following example report number, 14-0123, 14 = year and 0123 = sequential report number beginning with 0001 on January 1 of each year.
  • Date & Time Occurred: This is the date and time that the incident first occurred. In the following example, 25 Feb 2014 @ 13:10:27, the incident occurred on February 25, 2014, at 1:10:27 PM (Note: The time is expressed in 24-hour format.).
  • Location: This is the 100th block address and intersection information. translates address data into block level data. This means that if an incident occurs at 123 Main Street, it will show up as 100 Block Main Street in the application. Block ranges are used to provide confidentiality for victims. The location of the icon on the map is approximate based on the block range for any given street; it does not represent the actual location of the crime. Some location fields may be populated with “address could not be mapped” if the data was not geo-processed accurately. The following table provides several examples to demonstrate the block translation process:

Street Number

Block Translation

0 – 99

0 Block

100 – 199

100 Block

1000 – 1099

1000 Block

12000 – 12099

12000 Block

  • Nature of Crime: This is the type of report filed. If multiple crimes occurred, only the most serious crime will be listed, according to FBI Uniform Crime Reporting (UCR) hierarchy rules. Additional information can be found at

*Effective January 1, 2013, rape is defined as, “Penetration, no matter how slight, of the vagina or anus with any body part or object, or oral penetration by a sex organ of another person, without the consent of the victim.”

I called UCPD to report a crime or request assistance for an issue not occurring at my location, but the icon on the map reflects the location from which my call was placed (my residence) and not the location of where I reported the crime to have occurred. Why doesn't the map reflect the location of where the event actually occurred?

The application receives location information from the Department’s Records Management System (RMS). Data from the RMS system is based on information provided by the reporting person. Some crimes, such as identity theft, are classified as occurring at the victim’s residence even though the actual identity theft may not have occurred there. All location information is geo-processed to the 100th block or to the nearest intersection.

In some instances, the location of the report on may not represent the actual location of the crime. Some courtesy reports may plot near a hospital or police station where the victim filed the report. Generally, the location of the crime will be updated in the RMS system if/when it becomes available. Crime data is updated every morning.

How can I use the data from in support of community safety goals?

Data from can be reviewed and used to improve community safety. data is appropriate to consider and discuss as part of coordinated crime prevention initiatives. Members of the community are encouraged to continue partnering and problem-solving with UCPD while using data toward shared police-community goals.

Is every RMS report included in

Not every RMS report is included in Some reports are not displayed due to victim confidentiality or if disclosure may jeopardize an ongoing police investigation.

How often is data updated in data is updated automatically once per day and contains the most recent six months days of data online.
