What is metadata

Why do we need standards?

  • Standards are created to

    • Save time

    • Save money

    • Ensure quality

    • Ensure completeness


What is metadata

The importance of metadata

Poor documentation often leads to loss of critical information

Who’s mom?

Where was this taken?

How old is this photo?


What is metadata

The importance of metadata standards in libraries

Libraries have been using metadata for many years to describe, manage, and help locate publications and other items

What is metadata

Why a metadata standard for geospatial data?

  • To ensure all relevant information is documented

Height

Latitude & Longitude

Projection

Datum

Processing steps


What is metadata

Why should you (or your staff) write good metadata?

  • Your data is meaningless without it

  • So you won’t FORGET how you collected and processed YOUR OWN DATA

  • So information won’t be lost when an employee leaves

  • So the data can be used again in the future


What is metadata

What is geospatial data?

1990 Census

Miami 19.0 27.5 10.5

New Orleans 16.3 21.3 11.4

Portland 7.4 10.0 5.8

  • Any data with a spatial component including:

    • Maps

    • Charts

    • In situ data (data collected at a specific site or station)


What is metadata

Why other people should share their metadata with you

  • So you can find their data

    • So you don’t have to go out and collect it yourself

  • So you can tell if you want their data

  • So you can tell how to use their data


What is metadata

Benefits of sharing metadata

  • It enables individuals using data produced by anybody else (is that population data set related to 1960 or 2000?)

  • It prevents individuals from stealing your data (all sources are acknowledged)

  • It makes your data visible so others can see what you’re doing

  • It encourages others to share their data


What is metadata

Uses of metadata in information systems

As input to analysis tools

Map from USGS

SST data from NOAA

Buoy data from NBDC
