Spatial and Temporal Analysis: San Antonio Burglaries Neo Geo Spatial Detectives

SCOPE: San Antonio city limits (412 square miles) Burglaries of vehicles and habitations Neo Geo Spatial Detectives

Objective: Through the analysis of hot spots within “journey to crime”, determine any spatial, temporal or economic patterns in relation to burglaries committed within San Antonio’s city limits. Identify and locate any detractors of crime. Predict areas likely to experience spatial displacement as a result of increased policing in current hot spots. Neo Geo Spatial Detectives

Conclusion: Determine correlation between the distances from a criminals dwelling and the type of crime committed by the individual Determine areas of deficiency within patrol districts and help illustrate any common trends in San Antonio Identify any temporal patterns that may emerge from month to month Compare our findings to recent “Journey to Crime” studies, in order to determine any similarities Generate an Offender Residence Probability Surface Neo Geo Spatial Detectives
