Distribution of geographical information (GI) data is inherently linked to storage of the data and similar rules apply. There are two aspects to data distribution:
- Sending the data to another user (internally or a third party)
- Receiving data from a user as a resource
Important aspects to consider when distributing or receiving GI data are:
- Format
- Media
- Ownership and copyright
- Metadata
Media
Geographic information data files are often large in size and therefore careful consideration is needed when distributing the data.
Hard copy media
When considering the size of files involved, data distributed in this form of media are generally via CD or DVD.
Electronic data transfer
The future of GI distribution is through network and the internet data transfer.
This principle has already been commenced through the set up of GI Gateway and the IGGI node. Currently, the gateway only provides a resource directory of metadata, detailing available datasets and how to obtain this information. However, the future plans could well include access for authorised users to be able to download the relevant data.
The IGGI node is a connecting point within GI Gateway at which several government bodies come through to increase awareness of and access to their geospatial information.
Other important developments to be aware of are the Infrastructure for Spatial Information in Europe (INSPIRE) and the Public Sector Information (PSI) Directive. INSPIRE is a European project designed to provide better access to important data for community policy-making and implementation across all levels. The Information Directive defines the access to information gathered by public sector organisations (including educational institutions) by third party individuals and companies.
Ownership and copyright
As both a data distributor and a data receiver there are important aspects of the law that need to be considered.
As a distributor you need to consider under what terms and conditions do you want (or are required for) the data to be supplied to and used by third parties. For example, what accreditation will you receive for the data? Can the data be used for commercial gain?
As a receiver of data, similar rules apply. For example, what can the data be used for and how must you acknowledge the creators of that data?
