When we first announced the Google Maps Data API in May, we were excited to provide developers with free scalable hosting of geographic content. The idea was simple: to create an awesome maps mashup, you focus on creating a great user experience and Google will provide scalable hosting and bandwidth. Moreover, your data should be accessible from any platform (like desktop, iPhone, or Android) using your language of choice (including JavaScript, Python, Java, or Objective-C).




Today we're launching several exciting new features based on all the great feedback we've gotten from developers. First, we're adding geospatial and attribute search to your maps. To see these features in action, play around with this College Finder demo (you can download and modify the source code here). I created a Google My Map consisting of approximately 3000 U.S. 4-year colleges, and wrote a JavaScript app to search over this map (with no need to run my own server or database!).










Using the new search features, you can easily request "all colleges within 5km of San Francisco" and apply attribute filters like "[Type:public]". You can also sort the results by proximity to a point (in this case, the center of the map). The results are updated whenever the map is dragged or zoomed, or when the search criteria change.




In addition to search, many developers have requested the ability to enable API access to a public map without requiring users to be signed into a Google account. We've also enabled this today: you can indicate (using the API) that you would like a map to be accessible by others via the API. You can also programmatically control access to the maps you own, by making them public/private or adding specific collaborators. Our official docs will be updated soon but, in the meantime, check our forum for updates about this.



To get started writing your next awesome geo app, you can download and modify our sample code, or refer to our documentation. We look forward to seeing all the great collaborative mashups, store locators, and mobile apps you'll come up with.



If you have questions or feedback, or would like to tell us about your new creation, please visit our developer forum, tweet about #mapsdata, or file a feature request. We have some other great features on the way, so stay tuned and keep mapping!

We're really excited to announce two upcoming hackathons for our Google Geo APIs. The first will be held in New York City on November 20th followed by a second one in Mountain View on December 15th. This will be a great learning opportunity for any developer interested or currently involved in building Geo-enabled applications using our APIs. Come join us for a great session where you'll be able to hack away on your own projects alongside our engineers who'll be readily available to provide support.

Below is a list of the various Google Geo APIs you'll learn about:



Registration for these events are completely free, and space is limited. Reserve your spot now using the following links below!



Bring your laptops, your brains, and we'll see you soon!

Calling all Bay Area coders! We've just finalized another hackathon for late September! On September 24th, 2009, from 1:30 to 8, Google will host a hackathon for our Geo APIs in our San Francisco office. At the hackathon, Google engineers will give one or two API overview presentations and then will be on hand to answer all your geo related questions. You can work on suggested codelabs, or just bring your own project and we'll lend you a hand.



The hackathon will cover the following APIs:




Space is limited, so register now! And remember, this will be a code-heavy event, so bring your laptop and come ready to code!

September 3rd, 2009, from 11 to 6, Google is hosting a hackathon for our Google Geo APIs in our Seattle offices. At the hackathon, you can code on our Google Geo APIs, with the guidance of Google Engineers. We'll provide you with suggested codelabs, or you can just work on your own projects.

You can work on the following APIs: The Google Maps API for JavaScript V2and V3, the Google Maps API for Flash, the Google Earth API, KML, and the Google Maps Data API.

So bring your laptops, and your brains, and be prepared to code.

Space is limited, so register now!


From simple GPS tracks to rich KML documents to collaborative maps, the geo developer community has continually redefined and enriched the geoweb, giving rise to better canvases for geographic participatory culture. Notably, the Google Maps API and other tools have led to the creation of more dynamic and interactive content, putting new demands on the ways in which geodata is stored, accessed, indexed and rendered. To address these challenges, today we've released the Google Maps Data API in Labs, a Google Data API for viewing, storing and updating geodata on the web.

The Google Maps Data API is built on the following principles:


  • Storage should scale simply with usage. You shouldn't have to worry about maintaining a data store to build a cool Google Maps mashup. Focus on building the client, and we'll provide hosting and bandwidth for free.

  • Geodata should be accessible across platforms and devices. With many client libraries and clients, accessing stored geodata should be possible from anywhere, whether it's on the web, a mobile phone, a 3D application, or even a command line.

  • Realtime geodata requires realtime indexing. For a lot of geographic content, freshness is important. Geodata from the Google Maps Data API can be instantly indexed and made searchable in Google Maps.

  • Rendering geodata is better and faster with the right tools. Through JavaScript, Flash, 3D, static images and more, we'll continue to provide better ways to render your content to meet platform and latency demands.



Much like KML, the Google Maps Data API is based on a data model of maps (collections) and features (placemarks, lines and shapes). Since it uses this familiar model, this new API makes it easy to build geo applications for specific activities like planning and sharing trips, collaboratively mapping hiking trails, or saving a list of favorite restaurants. Also, for any map that is associated with a Google Account, that map is immediately available to view and edit in Google My Maps. Some examples of applications which already use the Google Maps Data API:


  • My Maps Editor for Android allows users to create and edit personalized maps from an Android mobile phone. Integration with the phone's location and camera makes it easy to document a trip with photos and text on a map.

  • ConnectorLocal is a service that informs users about the places where they live, work and visit by gathering trusted hyperlocal information from many sources. Using the Google Maps Data API, ConnectorLocal makes it easy for users to import and export their geodata in and out of Google Maps, and also improves their ability to have data indexed in Google Maps for searching.

  • My Tracks enables Android mobile phone users to record GPS tracks and view live statistics while jogging, biking, or participating in other outdoor activities. Stored with Google Maps Data API, these tracks can be accessed, edited and shared using the My Maps feature in Google Maps.

  • Platial, a social mapping service for people and places, uses the Google Maps API to host geodata for community maps on both Platial and Frappr.



If you're a developer, we encourage you to get started with the Google Maps Data API immediately with our HTTP protocol guide. Additionally, the team at We-Create (the company behind ConnectorLocal) has released their Webready library for PHP developers, built on top of the Zend Framework.

Of course, this release in Labs is only the beginning -- in the future, we'll continue to add new functions and libraries to make the API even better. In the meantime, we hope you'll get an early start in developing new applications and pushing the boundaries of the API. Be sure to stop by our group to ask questions, give us feedback, and let us know what you've made!
