Challenges and Best practices when working with location based data

This is a presentation I gave at a maps conference regarding the challenges when working with Location based data.

It is very interesting on how Location based data affects so many aspects of our lives today. In this presentation I talk about how we map locations to tiles for our maps and then every add or log that we receive is mapped to a certain tile at a specific time-period and how this helps us aggregating the data received.

It also talks about how we optimized hadoop to give us huge savings.
