Google will be retiring Latitude soon, along with Latitude's API. But they say on their blog that Location History will still be stored and users will be able to access their history on Google Maps' Location History Dashboard. Do you know if there will be any API for receiving that location history, as there was for Google Latitude?
I've discovered that I can dynamically load my location history for any date using the following url:
https://maps.google.com/locationhistory/b/0/kml?startTime=1373666400000&endTime=1373752800000
by changing timestamps in "startTime" and "endTime" parameters. Unfortunately it's in .kml and no granularity data is included. Come on, Google - Latitude has some devoted users who relay on it on daily basis, don't kill it :(
