, Implementation Components
1. Geospatial Data Development: Building data for
multiple uses
2. Metadata -- Describing geospatial data
3. Geospatial Data Catalogue -- Making data
discoverable
4. Geospatial Data Visualization: Web Mapping
5. Geospatial Data Access and Delivery – Open
access to data
6. Outreach and Capacity Building

data for multiple uses
• In the times of traditional ‘mapping’,
collection and distribution of geographic
information used to be highly centralized, or
controlled by powerful government
monopolies.
• This pattern was established since the
beginning of the history of mapping, and
lasted for centuries, until very recent times
3
, Organization Approach
• common spatial data are often defined through
community and/or national agreements on content,
known as framework" or "fundamental" data in
various national SDIs
• Existing data content may be enhanced, adjusted, or
even simplified to match a national or global
framework specification
