What is Metadata Definition: A collection of data Generally datasets can be defined as: o Spatial – a collection of logically related features arranged in a prescribed manner such as GIS map layers, water features, etc o Tabular – a file, spreadsheet, data in a table o Many tabular datasets are inherently “spatial”, e.g. water-quality samples associated with stream collection sites Elements in a dataset can include: o Values, measures, points, coordinates, conditions, qualities, frequencies, or attributes that are a result of an observational study

What is Metadata provide When you provide data to someone else, what types of information would you want to include with the data? receive When you receive a dataset from an external source, what types of details do you want to know about the data?

What is Metadata Providing data: o Why were the data created? o What limitations, if any, do the data have? o What does the data mean? o How should the data be cited if it is re-used in a new study? Receiving data: o What are the data gaps? o What processes were used for creating the data? o Are there any fees associated with the data? o In what scale were the data created? o What do the values in the tables mean? o What software do I need in order to read the data? o What projection are the data in? o Can I give these data to someone else?

What is Metadata Metadata is: Data ‘reporting’ WHO created the data? WHAT is the content of the data? WHEN were the data created? WHERE is it geographically? HOW were the data developed? WHY were the data developed? Photo by Michelle Chang. All Rights Reserved
