A visual representation of postal code boundaries within the city of Boston is a geographically indexed chart showing the spatial extent of each area. For example, such a chart illustrates the boundaries of 02115 (Back Bay), delineating it from adjacent areas such as 02215 (Kenmore Square). These charts are valuable tools for understanding local demographics, logistics, and service area definitions.
Such a visual aid is critical for various purposes, including targeted marketing campaigns, efficient delivery route planning, and precise geographic analysis of urban areas. Historically, these maps have evolved from simple paper documents to complex digital interactive systems, reflecting advancements in cartography and data management. They allow organizations to understand spatial distributions of data and resources.
