Countries States Cities Database
This project is a comprehensive geographic location dataset and reference library providing standardized data for countries, states, and cities. It serves as a source of truth for regional hierarchies, ISO codes, coordinates, and timezone information, available as both a relational SQL database and a document-based JSON library.
The project includes a custom dataset export tool that functions as a filtering engine. This allows for the generation of tailored geographic files in JSON, CSV, and GeoJSON formats by selecting only the specific regions or fields required.
The dataset covers global address validation and the implementation of cascading dropdown menus for user profiles and shipping addresses. It supports the deployment of location data across multiple relational and document database platforms, as well as integration via SDKs and APIs to retrieve city, state, and country metadata.
