BackgroundBackground three decades of GIS and spatial

data capture technology

an eclectic range of academic disciplines using GIS as a research and teaching tool

considerable cost and time invested in spatial data creation

*2006 spatial data audit at 4 universities: +500 dataset files, 100s of orphan datasets

Requires a spatial data managementspatial data management, discoverydiscovery and sharing solutionsharing solution delivered through portal technology and metadata metadata.

So what is So what is METADATAMETADATA?The word appears to be of Greek and Latin origin……

but metadatametadata represents something completely different……

Other benefits: data protectionOther benefits: data protection


protects investments of time and cost dedicated to dataset creation and development;

maintains an inventory of datasets to reduce time required to re-assess existing datasets for new and future applications;

ensures integrity of existing and new datasets using metadata as a tracking mechanism to monitor changes and edits to datasets;

reduces and minimises the disruptive effects of staff taking annual leave or departing for new careers;

eliminates or reduces the risk of redundancy in dataset collection;

saves against accidental deletion of dataset files.

Defines and describes metadata entities and elements and, classify and group relevant metadata elements with entities.

Assigns structure and conditions (obligations, data type, domain).

Why publish metadata on the GoGeo portal?Why publish metadata on the GoGeo portal?

a repository for you to store and manage your metadata thus savings in cost and time;

use metadata to announce your data and applications;

advertise (and sell?) your spatial datasets to other interested parties in academia and in the private and public sectors;

metadata in the portal can be referenced and cited for project proposals;

could be configured as an internal resource to access and share datasets.

* Cambridge, Edinburgh, Kingston, Leeds, Leicester, Sheffield and Southampton universities have created and published +200 metadata records on GoGeo portal (global and private).
