Metadata helps you do your job. Looking for a geospatial dataset? Search engines, such as the national Geodata catalog at data.gov, read metadata.
Did you find a dataset but you are not clear about what it represents? Read the descriptions, definitions and process steps in the metadata.
Do you offer data for download and get repeated questions from users? Write the answer once—in the metadata.
As a GIS professional, you can store a lot of knowledge in your head, but what happens in your absence? Undocumented data lose their value. A new user cannot trust datasets that are not fully described. Someone may not find the earlier dataset or not be confident in a found file, and waste time and money in duplication of effort. Writing and editing metadata may seem time consuming, but metadata pays off for you and other GIS users.
See these Federal Geographic Data Committee (FGDC) publications for more information about the use and value of metadata:
