Based on this announcement from Google if you haven’t taken a close look at the Google Maps Data API yet you may want to consider doing so now with the addition of spatial and attribute search capabilities to the API. Search Feeds, similar to Feature Feed URL’s, take the form:
Spatial queries can accept either a bounding box or a radius (from a lat/long center point) to use as the input geography for performing a searching. Matched features within a defined area can also be sorted by distance from the input lat/long. In the code below a bounding box is used as the input search geography.
Attribute searches can be implemented against a feature’s structured key/value pairs. An array of key/value pairs are passed in to the query as seen below where we are searching for all features in a map containing the attributes pool: true and price:budget.
I don’t see mention of the capability of combining spatial and attribute queries but I would assume that you only need to include the appropriate parameters for each.
This is a nice addition to the Maps Data API and will make it a much more attractive platform for web mapping applications. Obviously it doesn’t provide advanced search capabilities, but for simple applications it is an attractive solution.
