OSM-PH topic outline for lightning talks, quickies, workshop, and conferences.

Introduction

Overview

OpenStreetMap (www.openstreetmap.org) is a worldwide project which aims to create and share geospatial information to anyone who wants them. The project was started because most maps you think of as free actually have legal or technical restrictions on their use, holding back people from using them in creative, productive or unexpected ways.

More and more people are contributing and using the data in various ways. Local government units and other government agencies are encouraged to use and update the data so that the public may benefit from the shared information particularly for disaster risk reduction.
