Open Data in the Geospatial Context

Presentation given in the Open Source block on Thursday afternoon.

Abstract

The term "Open Data" touches a broad range of aspects concerning data access, ownership, copyright, licensing and policy but not well defined. This presentation will clarify all major aspects concerning Open Data. Without a clear definition there is a lot of potential for misunderstanding depending on who is using it in which context. At the same time Open Data has become a core term used in data policies which also calls of a much clearer definition. Increasingly businesses are looking into how Open Data can be leveraged to create added value. To bring clarity into this situation the Open Source Geospatial Foundation (OSGeo) maintains a white paper on Open Data in the geospatial context. It contains a clear definition of the terms, puts them into context and offers an additional set of criteria to more precisely define the scope of Open Data. It can be split into three major types:

  1. Factual data collections where values should not be modified (e.g. temperature measurement, speed control data).
  2. Authoritative data which is part of a legal framework and system.
  3. Community processed data which is created and maintained in an open and transparent consensus process.

Finally the presentation will give examples of commercial uses of all three types of Open Data.
