Display Field: Name

Type: Feature Layer

Geometry Type: esriGeometryPoint

Description: These points represent police station facilities selected for service area modeling using Network Analyst in ArcGIS Pro. Only stations located within or near statistically significant arson hotspot clusters were included, ensuring realistic emergency coverage analysis. Each facility acts as a source location for the creation of 2-, 5-, and 10-minute travel-time polygons representing police response accessibility. This dataset supports emergency planning and hotspot-based risk mitigation for arson in Chicago.Temporal Scope: January 1 – December 31, 2020.
