Crime in New Delhi will now be mapped in real-time and a “predictive policing” mechanism developed by the ISRO will help the cops identify gangs besides building a database on the kind of crimes that happen in any particular area.
Called Crime Mapping, Analytics and Predictive System (CMAPS), the technology will help a Delhi Police official analyse data and patterns of crime in the city and help in better optimisation of available resources.

Cops will now be armed with Personal Digital Assistant (PDA), a device that will keep them connected to a central processor, which stores records of more than two lakh criminals.
Officials visiting a crime scene will get all vital information at the scene itself and will be able to report the same without having the need to visit the police station.

Police said that the system will be able to convert distress call into a digital message with the location of the caller being flashed through global positioning system.
Even gangs operating in specific areas can be identified in real time. The data stored by the system will be able to point out the frequency of what kind of crime is more in which area of the city.

For example, if mugging is a common problem in any area, cops will be able to strategise and plan security measures based on the data. “The specific prediction can also lead to arrest of criminals,” the senior official said.
A similar system is used in some developed countries of the world. Also called ‘Geographic Profiling’ or Geographic Information System (GIS), such a method helps in narrowing down the location of the criminal based on the kind of crime being committed.
For example, a high frequency of chain snatching in an area points to the fact that the chain snatchers are operating from a base in and around the area itself.
The system can not only be effectively used to solve cases of serial murder or rape but also arson, bombing, robbery, and even terrorism.
Besides Delhi cities like Mumbai, Goa, Chennai, Kolkata, Hyderabad, Bangalore and Trivandrum use a form of the GIS, the system is still in a rudimentary stage. As of now crime mapping is a periodical process conducted manually by gathering electronic data at an interval of 15 days. A version of the CMAPS is already being used for standalone systems. It will soon be upgraded to a web application.
