Mapstraction is a programming library that provides a common interface for numerous javascript mapping libraries to enable switching from one to another as smoothly as possible. Developers can code their web applications once, and then easily switch the mapping provider based on project needs, terms and conditions, and new functionality.

Users can switch maps as desired based on personal taste and quality of maps in their local area. Various tools built on top of Mapstraction allow users to easily integrate maps into their own sites, and configure them with different controls, styles, and provider.
