Earlier this week Google announced a new feature for its Maps Data API (check out our Maps Data API Profile) that will have a significant impact on how developers upload, and subsequently access, geospatial data in the cloud: data can now be uploaded to Google's infrastructure in either KML or CSV format.
Navionics announced a new web mapping API in Java to bring its navigation charts and other content to developers. The Navionics API is free, and is not to be incorporated in a fee-based website at this point. Of the three tiers for pricing, silver, gold and platinum, the API does not access the top of the line product. Languages supported are English, French, German, Italian and Spanish. A sign up is required to access the API's technical information.
RentRent.org has announced the creation of an API that searches local Craigslist entries for rental properties including apartments and houses. This gives developers the ability to integrate rental searches with mapping applications and APIs (our RentRent API profile has details). [Note that RentRent.org is not associated with Craigslist.org.]
