Mapstraction is a cool library for those who are doing applications that need support for more than one mapping providers. Im doing an application which needs to switch between Google, Mapquest and Map24 and it was kind of cumbersome to incorporate all the features in each of these providers. There were cases when the same feature is not available in all the three providers and thats when I hit upon Mapstraction.
The good thing about mapstraction is that in addition to abstracting the interfaces, it also provides some gaps that are not implemented by specific providers.
