Address Geocoding

Definition

Address geocoding converts textual addresses (e.g., “1600 Pennsylvania Ave”) into geographic coordinates (latitude/longitude). It uses reference datasets (e.g., street networks) and algorithms to interpolate positions, often with varying accuracy based on data quality.

Application

Essential for logistics (e.g., delivery routing), emergency services (E911 systems), and demographic analysis. Real estate platforms geocode listings for proximity searches. Public health agencies map disease outbreaks by patient addresses. Reverse geocoding (coordinates to address) aids fieldwork navigation. Tools like Google Maps API or Esri’s Geocoding Service automate the process.

FAQ

1. What factors affect geocoding accuracy?

Address formatting, reference data completeness, and interpolation methods.

2. How is geocoding used in marketing?

To target customers by location or analyze sales territories.

3. What’s the difference between geocoding and geotagging?

Geocoding converts addresses to coordinates; geotagging embeds location metadata into files.

4. Can geocoding handle non-standard addresses?

Advanced parsers can, but errors may occur.
