As we continue our recovery and cleanup efforts, please visit the Emergency website for the latest information on openings and closings in Miami-Dade County.
Metadata is essentially “data about data”. It provides vital information on the, how, what, when, where, and why about the data to users and maintainers of the data. It provides the data limitations, scales, reference, contact, correctness, attributes, processes, and how the data was created to name a few. It is meant to inform and protect against incorrect and inaccurate data usage during mapping and analysis process, which can be costly to any organization.
Miami-Dade County’s (MDC) metadata standards follows the Federal Geographic Data Committee (FGDC), Content Standard for Digital Geospatial Metadata (CSDGM), one among several other metadata styles and profiles supported by Esri ArcGIS Geographic Information System (GIS) software. Nonetheless, Miami-Dade County plans to migrate to a newly adopted International Organization for Standardization (ISO) when the new templates is made available in Esri software. Esri tools will be used to convert metadata from FGDC to ISO format.
The GIS Central Data Repository (GCDR), also referred to as “Production”, consists of hundreds of GIS layers, and metadata is enforced by the County’s Data and Metadata Administrator. This process facilitates the goal of achieving 100% metadata documentation for production layers. Public layers metadata can be accessed via the County's GIS Self Services site.
With that said, the County developed basic GIS Metadata standards and procedures to aid our GIS users with the collection, creation and maintenance of metadata. GIS metadata training and assistance were provided through workshops or on a one-on-one basis, as needed. To aid users with the reengineering of ArcGIS metadata style, the County applied for, and was awarded a 2012 FGDC Metadata Trainer and Outreach Assistance grant. This grant allowed staff to extend metadata training and outreach assistance beyond MDC employees that included local municipalities, regional areas, GIS partners, and it allowed sharing of the materials developed through the grant. In addition, the county published GIS Metadata to GIS Inventory portal through another grant, to aid in GIS data discovery and sharing initiatives.
