Update: Amazon’s Map API and other LBS News

Amazon's Map API first announced in September is now (as of Tuesday) part of the fully functional Amazon Mobile SDK for building on its Kindle Fire devices.

What does it do?

  • Interactive Maps. You can embed a Map View in your app for customers to pan, zoom and fling around the world. You have the option to display a user’s current location, switch between standard maps and satellite view, and more.
  • Custom Overlays. You can display the locations of businesses, landmarks and other points of interest with your own customized markers and pins.

Among the current users of Amazon Maps: Hipmunk, Evernote, Trulia and Zillow.

Word came Monday that Amazon is now offering a developer API for map apps for many of its Kindle Fire tablets. The big news is (1) that such an API exists and (2) it's not from Google but rather Nokia (Engadget). Data layers are rather limited and the focus seems to be on Google Maps developers; "Google Migration Path" is a link at the top of the page. The app sales are akin to Apple's: developer gets 70%, Amazon 30%.

Foursquare is holding a second hackathon.

On November 3, we’ll open up our NYC & SF offices for an all-day Connected Apps hackathon. And like last year, we’re inviting developers all around the world to band together and hack up some awesome connected apps. We’ll have great prizes (last year one of the winning teams had their hack running on a giant screen in Times Square and even rang the closing bell for NASDAQ! Oh, and there’s a new title belt!), swag, and (naturally) global glory for the best foursquare hacks, no matter where in the world they come from.

A new study by SIgnal using tech from Spirient shows that while GPS chips may be comprarable, once you put them in a phone, sensitivity can be severely impacted.

Based on the performance criteria that were used to conduct the analysis, the report indicates that the performance of today’s A-GNSS chipset platforms is largely comparable. Further, the study found that the introduction of multi-GNSS capabilities (A-GPS and GLONASS) can significantly improve the overall performance of the platform versus A-GPS alone with respect to its ability to obtain an accurate fix in a timely manner.

However, a key finding in the report is that the overall performance consistency of A-GNSS platforms does not extend to their commercial implementations in leading smartphone models. In addition to the significant inherent location performance differences in the smartphones that were tested, the results indicate that in at least one instance, the introduction of a commercially-obtained protective case reduced the A-GPS receive sensitivity by a factor of more than 6 (8.2 dB).
