USGS Geoscience Data Catalog

Metadata are data about data. We provide geospatial metadata, information about geospatial data such as images of the earth, maps and the geographical features that maps represent. Geospatial metadata are structured in a consistent way so that once you get used to the format, like cards in a library catalog, it becomes easy to find out what you need to know.

People who produce geospatial data are concerned about how to document the data resulting from their studies. But people who manage a collection of metadata have a number of different concerns that often aren't discussed in metadata-training materials, and extend beyond the relatively simple matter of making a collection accessible through the Clearinghouse. If you're managing a collection of metadata, you might be interested in these reports:

• Diagram showing how metadata are processed
• How the metadata records are maintained in this catalog
• Improving access to metadata using keywords from controlled vocabularies
• Using scripts to fix common metadata problems thoughout a collection
• Modifications to Isite code to support enhanced logging
• Use of this catalog to download metadata records
  • by real people using the web
  • by search-engine robots using the web
  • search terms people used to find records yesterday

using this catalog (USGS Geoscience data):

• Browse by geographic location
• Browse by publication series
