Adresswerte

Adresswerte are the individual components that make up a postal address used in information systems, mapping, and data processing. Common address values include street name, house number, postal code, city or locality, state or province, and country. In many countries, these values are standardized according to national addressing schemes or international standards such as the Open Geocoding Protocol (OGC) and the International Organization for Standardization (ISO) 19160.

In geographic information systems (GIS) and spatial databases, address values are stored as attributes of spatial features. They can be linked to geometry, which allows for address routing, geocoding, and reverse geocoding. Accurate address values are essential for navigation, emergency services, mail delivery, and demographic analysis.

Standards for address values differ by country. For example, the United States uses the Address Management System (AMS) and the Federal Geographic Database Committee standards, whereas in Germany the "Kartenstandards" and the "German Address Data Model" provide detailed guidelines. Internationally, the Data Quality International (DQI) guidelines are often applied to ensure consistency and interoperability.

Software applications such as GIS platforms, web maps, and logistics systems often provide address validation services. These services compare entered address values against authoritative datasets to detect missing or incorrect components, thereby improving data quality and user experience.

In summary, Adresswerte are the fundamental data elements that represent a physical location in address terms. Their consistency, validation, and proper integration into spatial data models underpin many modern location-based services and informatics solutions.
