Geocoding
Definition
Geocoding is the process of converting text-based address or location descriptions into geographic coordinates (latitude and longitude). This foundational GIS operation enables spatial analysis, visualization, and navigation.
Application
Marketers map customer locations. Health officials analyze disease spread by region. Logistics teams route deliveries. GIS systems translate addresses into mappable coordinates using reference datasets and address locators.
FAQ
What is required for geocoding?

Why is it essential?
It links non-spatial data to maps, enabling visualization and spatial querying.
Where is it used?
E-commerce, disaster mapping, real estate, health analytics, and public safety.
What affects geocoding accuracy?
