The GBIF Data Portal
INTRODUCTION
The GBIF Data Portal is at present the main tool to access the data available in
the GBIF distributed network. This presentation is a guided tour over its
different features, starting at the most basic ones and ending with the most
advanced.
Recently added features as the ‘data sharing with
countries of origin’ table or the capacity to make
searches using ‘altitude/depth’ criteria are
highlighted.
This lecture is presented by Tim Robertson, Systems
Architect at the GBIF Secretariat in Copenhagen,
Denmark.

FUTURE
1. Widening accessibility of the data:
• Mirror sites
• Regional mirrors
• Simplified portal package
2. Improving mapping support:
• Alternative base layers in the portal
• Dynamic zoom from cell density to individual localities
• Support for Open GIS Consortium web services
3. Improving the use of metadata:
• Better metadata characterising each dataset for different uses
• New registration interfaces
• Control of indexing schedules
4. Scaling the database (to a billion records and beyond)
5. Translation into more languages
The GBIF Data Portal
CONCLUSIONS
• Portal already available on the internet, open and accessible to everyone.
• Developed in Java. It is Open Source software, that can be adapted to other
purposes.
• Copies (mirror sites) running in different parts of the world.
• Different ways to consult the data: taxonomic, geographical, origin.
• Different ways to access the data: tables, maps, Google EarthTM downloads...
• There is also machine-driven ways to access the data: web (REST) services,
OGC services, etc.
• In the future:
• More distributed and customised.
• Improved map support.
• Improved use of metadata.
• Scaling (108 records).
• Translation.
