A geographical representation delineating the boundaries of Baltimore, Maryland, is often enhanced with postal code designations. These alphanumeric identifiers are overlaid onto the city’s cartography to provide precise location-based information. An example would be a map showing the distinct areas of Federal Hill (21230), Fells Point (21231), and Roland Park (21210), each clearly demarcated by its respective code.
The integration of postal codes with spatial data provides numerous advantages. Businesses utilize these maps for targeted marketing, logistical planning, and service area definition. Government agencies rely on them for resource allocation, emergency response, and demographic analysis. Historically, these maps have evolved from simple street layouts to complex digital renderings incorporating real-time data updates and geographic information system (GIS) capabilities. Access to this visual data allows for efficient decision making and improved operational effectiveness.
