Neighbourhood and crime

What type of maps, boundaries and data do you think need to be added to the presentation? What type of analysis have you seen these components used for? Digital maps have been found as the quickest ones for visualizing a crime scenario. Through this map, certain important things like locations of crime events, arrests, etc. can be ascertained or be displayed. Community characteristic has been another form of data that need to be displayed on maps. Separate identifier could be used for slums, market-places, schools and colleges, parks, red light area, etc.

The crime pattern can also be found to be useful in interpreting some relation between a community characteristic and form of crime. Other mapping data could be roads and bus routes, housing societies and possible relationships between the neighbourhood and crime.  The presentation showed a number of examples of law enforcement using GIS data. List another example of how this technology can be used in law enforcement. GIS has been quite useful in identifying potential suspects so that the investigators could figure out any lead especially in those cases when no breakthrough could be made with given list of evident.

In case of serial offence, GIS helps in the investigation through the display of home addresses, work addresses and places often frequented by the victim or the suspects and which places could possibly be the strong link between the crime, suspect and the victim. Behavior pattern of an individual can also be marked right from early childhood like individuals with repeated offences of peeping tom incidents and indecent exposure can be a possible rapists in a given case or cases in future.

Question 3: The presentation showed a number of homeland security and natural disaster examples. Describe at least one additional usage of the software in improving homeland security and emergency preparedness. GIS support has its application for all the disaster prevention phases but the most important concern has been but the use of the same in physical planning in prevention as well as mitigation phases. Threat and the calculation of its magnitude of natural phenomena through GIS is meant for ascertaining the risk for any area.

Calculation of damage and its extent is also important as GIS can make an assessment like what was before and what is now left and then how much is the loss.
