What is metadata in a GIS?
Metadata is information about data. Similar to a library catalog record, metadata records document the who, what, when, where, how, and why of a data resource. Geospatial metadata describes maps, Geographic Information Systems (GIS) files, imagery, and other location-based data resources.
Why is metadata important in GIS projects?
Metadata makes spatial information more useful to all types of users by making it easier to document and locate data sets. Because spatial data is the fuel of a GIS, it is important to know if the data will meet user needs. Data users need metadata to locate appropriate data sets.
